Create a new electronics design. Schematic.
00:05
After completing this video, you'll be able to
00:08
create a new electronics design.
00:10
Create a new schematic, connect symbols with nets and edit symbol values
00:16
in fusion.
00:17
We wanna begin by creating a new electronics design by
00:20
going to our file menu and selecting new electronics design.
00:24
The new electronics design is a container for our schematic and our PC B.
00:29
There are more elements of an electronics design such as the three DPC B.
00:34
But these are the two main items that we need in order to build and design our PC B.
00:39
We want to get started by saving this,
00:41
making sure that we have a correct project location
00:43
and I'm gonna call mine the PC B module.
00:47
Once we have this container saved, we're gonna select new schematic.
00:51
The schematic is gonna be our two D blueprint of all of
00:55
the different components that go into our design and how they're connected.
00:59
We'll take this two D schematic and we'll move
01:01
it into our two DPC B or printed circuit board
01:04
that will define the physical size and location of all
01:08
of the various components and how they're connected together.
01:10
But before we get into that, we need to talk a little bit about the user interface.
01:15
When you first come into a fusion electronics design,
01:18
the user interface is likely set to a stack.
01:21
Now,
01:21
this means that all of our tools are stacked above each other in the left hand side
01:26
and we can collapse and expand this as needed.
01:29
But it's generally easier for us to right click and convert this to tabs.
01:33
The tab interface gives us a lot more room to work in each of these menus.
01:37
Noting that we can only really see one at a time.
01:40
But for example, when we're placing components,
01:43
having a larger list of components is much easier for us to traverse.
01:46
Rather than looking at a shortened version in the stack setup.
01:50
On the right hand side,
01:51
the inspector and selection filters can be collapsed
01:54
to give us a little bit more working room
01:56
and we can expand them whenever we need
01:58
to access information about selected symbols or components.
02:02
Also, let's note that our view section has grid settings.
02:06
And by default, we're working on a 0.1 inch or 2.54 millimeter grid
02:11
inside this menu. We can also toggle on or off the grid settings.
02:14
If this helps you during your layout process.
02:17
For our video, we're going to turn this off using the default settings.
02:22
The last thing that we want to note is in our user preferences
02:25
inside of our user preferences.
02:26
For electronics, we can set the schematic to a dark theme.
02:30
And by default, we can see the PC B is set to dark,
02:33
but we can also switch that to a light theme
02:36
for our video.
02:37
We're gonna focus on using the default settings leaving this as a light theme.
02:41
But note if you're more comfortable working in a dark theme, you can switch yours
02:45
now that we have that basic introduction to the U I.
02:48
Let's talk about what we're designing.
02:50
We're gonna be building a simple device with a
02:52
voltage regulator to convert 12 volts to five volts.
02:56
We'll add an led to the design to make sure we know when it's powered up
02:60
and we'll be using two NPN transistors.
03:02
So that way we can have 12 volt inputs and
03:05
then we can have a five volt output registered.
03:08
So that way we can use a micro controller to read whether or not we've got a signal.
03:13
So this basic board is going to allow us
03:15
to explore the creation process of using through hole components
03:19
to get started. We first want to add our voltage regulator.
03:23
So we're gonna navigate to all libraries and focus just on IC Power Management.
03:28
This will reshuffle the list that we see inside of our place components, dialogue
03:34
only giving us the information that's inside of our IC Power Management Library.
03:39
We're gonna be using the LD 1117
03:43
and note the drop down arrow on the right hand side
03:45
tells us that there are multiple variants or package sizes available.
03:50
There is a surface mounted version in an SOT 22 3
03:54
and we also have a to 220
03:56
because we're building a through hole board.
03:58
We want to make sure that we do grab the through hole or to 220.
04:02
We're gonna drag this onto the screen and then we're
04:04
gonna place this in the upper left hand area.
04:08
Remember that this is our blueprint or schematic that's going to allow us
04:12
to define all of the components we need and how they connect together.
04:16
We're going to navigate back to all libraries.
04:18
And for the next component, we're simply going to use the filter option.
04:22
In this case, we want to look for an NPN transistor.
04:26
We're gonna note that we have multiple package options and we
04:29
want to make sure that we're using the to 92.
04:31
We're gonna drag this onto the screen
04:33
and we need two NPN transistors.
04:35
I'm gonna place one here and another one down into the right.
04:39
Making sure that everything is easy to access and that we don't
04:43
have everything too close together is an important step in this process,
04:46
making sure it's clean and easy to see.
04:50
The next thing that we want to add is going to be our led.
04:53
I'm gonna type in led.
04:55
And as we look through this list,
04:57
notice that some of these led s are coming from our led library.
05:00
While others are showing up in IC Power Management, for example,
05:04
we want to find led
05:06
and then in our drop down list, we want to take a look at the various package options.
05:11
Now, as we scroll through, if we don't see the correct package option,
05:14
we need to make sure that we move on and we find the correct led that we need.
05:19
In this case, I'm gonna change the filter
05:22
and I'm gonna turn off the all libraries looking just in the led library.
05:26
Now, as we look in the led library,
05:28
we're going to go to our drop down list and just
05:31
take a look at the package options that we have.
05:33
In
05:33
this case, we want to use a round five millimeter led and
05:37
we're going to drag this onto the screen
05:39
using our right mouse to rotate it 90 degrees
05:42
and we'll place it in the upper right hand corner.
05:46
Next, we want to add a few connectors.
05:48
The connectors are gonna be in our connector library
05:50
and we want to use what's called AJ ST connector.
05:54
And once we look through the JST list,
05:56
note that there are several here and navigating through the various options will
05:60
help you identify the different nomenclature
06:02
in the component descriptions and names.
06:04
Now, we're looking for a four pin connector.
06:07
So we're going to select the B four B version
06:09
noting that there are no other variants or other options.
06:13
So we'll drag this into the screen.
06:15
We're gonna place one of them on the right hand side and then we'll use the
06:18
middle mouse button to mirror this and place the other one on the left hand side
06:22
and select done or hit escape on the keyboard.
06:25
We still need to add a couple of resistors as well as power and ground symbols.
06:30
So for this, we'll clear out our filter, go back to all libraries
06:34
and we want to start by selecting V plus.
06:37
Now V plus is our voltage and we're gonna drag this onto the screen,
06:41
placing one above our left hand JST connector giving it the 12 V value.
06:47
And then we're gonna place a second one here right next to our voltage regulator,
06:52
we'll hit escape.
06:53
And the next thing we want to look for is ground.
06:56
We're gonna use GND.
06:57
We'll select the first ground from our tutorial library.
07:00
We'll drag it onto the screen and we'll place it here
07:03
giving it a value of GND.
07:06
Then we're gonna ground our voltage regulator.
07:08
We're gonna ground each one of the transistors and we also need to ground our led.
07:13
We'll place a ground symbol over here and our output connector.
07:18
The next thing we need are a couple of resistors.
07:20
Now, the resistors can be found a few different ways.
07:23
These are going to be in our tutorial library and
07:25
I'm gonna search for them by using R dash us
07:29
for R dash us. Notice on the right hand side, we have a couple of options.
07:33
There are two through hole resistors here and
07:36
we're gonna be picking the 7.2 millimeter pitch.
07:40
We're gonna drag this onto the screen.
07:42
We're gonna have a resistor for the input of the first NPN transistor.
07:46
The input for the second,
07:48
we're gonna have one for our led
07:51
and then we're going to use the right click to rotate our resistor.
07:55
We're going to place one above this NPN transistor leaving a little
07:59
bit of space and one above this one here as well.
08:01
Hitting escape to get off of our tool.
08:04
Now that we've got everything placed on the screen,
08:06
we can begin connecting them together with what's called a net
08:10
on their connect menu.
08:11
We'll select net or use R on the keyboard and we'll start by
08:14
selecting and placing a net between our JST connector and 12 volts.
08:19
We'll do the same thing over here for our voltage input to our voltage regulator.
08:23
And then we'll also connect our ground
08:26
as we take a look at some of these other components.
08:29
We're gonna go from PIN two on our JST.
08:32
We're gonna left click to have a jog in our net and then we're gonna left click again
08:37
to place it as our first resistor.
08:39
We're gonna do the same thing over here keeping everything fairly similar.
08:44
We left click and then we'll click here to end that one.
08:48
We're gonna connect the resistors to the top of our NPN transistors,
08:52
we'll connect our ground,
08:53
we'll go from our led to ground
08:55
and then we need to go from our voltage output on our voltage regulator
08:60
all the way over to our third resistor for our led.
09:03
And then we're going to have a couple of points where we come off of this,
09:07
of our five volts
09:08
will come down
09:09
and we'll take this five volts directly into this resistor
09:12
will come down and take it into this resistor.
09:15
And then we also need to take it out to pin one.
09:18
So just to the right, we'll go down
09:20
and we'll work our way over to pin one.
09:24
Also note that we need to pull voltage between the resistor and the NPN transistor
09:29
because we are using this as somewhat of a switch or switching between ground.
09:33
So when the voltage goes low, we know that we have a signal on the input side.
09:38
So we're gonna connect from here to pin three
09:41
and we need to do the same thing for this one here.
09:43
Now, everything so far has been fairly easy to connect and clean,
09:47
but now we need to jump a few wires.
09:49
What we're gonna do is we're gonna make our way straight across
09:53
left click and make our way down. We left click again and over to pin two,
09:58
we're going to hit escape. And now everything has been connected
10:02
oftentimes when we begin to lay out a schematic,
10:04
it can be very easy to get things in a situation where
10:07
we have a lot of points that are jumping over other nets.
10:11
You want to make sure as you look at your own schematic that the green dots
10:15
or intersection points are only where you need
10:17
your nets to be connected to other nets.
10:20
You can reposition these at any point in time, moving symbols
10:23
and moving nets around just to make things a little bit more clean and easy to read.
10:28
Now that we have everything laid out.
10:30
The last step in our process is to define the values for our resistors.
10:35
We can do this a couple of different ways.
10:37
But the main option that we're gonna take a look at is
10:39
under modify and selecting value or using V on the shortcut keys.
10:43
We're gonna select the first resistor and we're gonna give this a value of one K
10:49
we're gonna select OK.
10:50
And we'll do the same thing for R two giving this a value of one K.
10:55
The next one that we wanna select is R four and this one is gonna be 4.7 K.
11:00
We're gonna select R five. This will also be 4.7 K
11:05
and R three is gonna be 100 and 20 ohms.
11:09
This is gonna allow us to add and store those values on each of those components.
11:14
So that way when they're shown on a parts list or a bill of materials,
11:17
when we manufacture a board,
11:19
we'll know exactly which resistor gets which value.
11:22
Note that we can expand the inspector,
11:25
we're gonna hit escape to get off of a value tool and select resistor three.
11:29
Notice that when we select resistor three, it's shown as the name R three
11:34
and it shows its component and all the way in the bottom, it shows its value
11:38
inside of this value category. We could also make changes to its overall value.
11:42
If we wish. In
11:43
this case, we want to leave it at 100 and 20 ohms.
11:46
But the inspector is a great way to
11:48
also add additional detail such as changing the name
11:51
or some of the description or properties of various components.
11:55
Not all values can be changed and not all components
11:58
or symbols will have available options to change those values.
12:02
You can push or override some values if you wish.
12:05
But in most cases,
12:06
resistors and capacitors are going to be main
12:09
components that you are adding those values to
12:12
at this point. Let's make sure that we have saved our schematic.
12:15
We're going to call this one, our PC B
12:18
module schematic.
12:20
And once this is saved, we can go ahead and move on to our next step.

00:02
Create a new electronics design. Schematic.
00:05
After completing this video, you'll be able to
00:08
create a new electronics design.
00:10
Create a new schematic, connect symbols with nets and edit symbol values
00:16
in fusion.
00:17
We wanna begin by creating a new electronics design by
00:20
going to our file menu and selecting new electronics design.
00:24
The new electronics design is a container for our schematic and our PC B.
00:29

00:34
But these are the two main items that we need in order to build and design our PC B.
00:39
We want to get started by saving this,
00:41
making sure that we have a correct project location
00:43
and I'm gonna call mine the PC B module.
00:47
Once we have this container saved, we're gonna select new schematic.
00:51
The schematic is gonna be our two D blueprint of all of
00:55
the different components that go into our design and how they're connected.
00:59
We'll take this two D schematic and we'll move
01:01
it into our two DPC B or printed circuit board
01:04
that will define the physical size and location of all
01:08
of the various components and how they're connected together.
01:10
But before we get into that, we need to talk a little bit about the user interface.
01:15
When you first come into a fusion electronics design,
01:18
the user interface is likely set to a stack.
01:21
Now,
01:21
this means that all of our tools are stacked above each other in the left hand side
01:26
and we can collapse and expand this as needed.
01:29
But it's generally easier for us to right click and convert this to tabs.
01:33
The tab interface gives us a lot more room to work in each of these menus.
01:37
Noting that we can only really see one at a time.
01:40
But for example, when we're placing components,
01:43
having a larger list of components is much easier for us to traverse.
01:46
Rather than looking at a shortened version in the stack setup.
01:50
On the right hand side,
01:51
the inspector and selection filters can be collapsed
01:54
to give us a little bit more working room
01:56
and we can expand them whenever we need
01:58
to access information about selected symbols or components.
02:02
Also, let's note that our view section has grid settings.
02:06
And by default, we're working on a 0.1 inch or 2.54 millimeter grid
02:11
inside this menu. We can also toggle on or off the grid settings.
02:14
If this helps you during your layout process.
02:17
For our video, we're going to turn this off using the default settings.
02:22
The last thing that we want to note is in our user preferences
02:25
inside of our user preferences.
02:26
For electronics, we can set the schematic to a dark theme.
02:30
And by default, we can see the PC B is set to dark,
02:33
but we can also switch that to a light theme
02:36
for our video.
02:37
We're gonna focus on using the default settings leaving this as a light theme.
02:41
But note if you're more comfortable working in a dark theme, you can switch yours
02:45
now that we have that basic introduction to the U I.
02:48
Let's talk about what we're designing.
02:50
We're gonna be building a simple device with a
02:52
voltage regulator to convert 12 volts to five volts.
02:56
We'll add an led to the design to make sure we know when it's powered up
02:60
and we'll be using two NPN transistors.
03:02
So that way we can have 12 volt inputs and
03:05
then we can have a five volt output registered.
03:08
So that way we can use a micro controller to read whether or not we've got a signal.
03:13
So this basic board is going to allow us
03:15
to explore the creation process of using through hole components
03:19
to get started. We first want to add our voltage regulator.
03:23
So we're gonna navigate to all libraries and focus just on IC Power Management.
03:28
This will reshuffle the list that we see inside of our place components, dialogue
03:34
only giving us the information that's inside of our IC Power Management Library.
03:39
We're gonna be using the LD 1117
03:43
and note the drop down arrow on the right hand side
03:45
tells us that there are multiple variants or package sizes available.
03:50
There is a surface mounted version in an SOT 22 3
03:54
and we also have a to 220
03:56
because we're building a through hole board.
03:58
We want to make sure that we do grab the through hole or to 220.
04:02
We're gonna drag this onto the screen and then we're
04:04
gonna place this in the upper left hand area.
04:08
Remember that this is our blueprint or schematic that's going to allow us
04:12
to define all of the components we need and how they connect together.
04:16
We're going to navigate back to all libraries.
04:18
And for the next component, we're simply going to use the filter option.
04:22
In this case, we want to look for an NPN transistor.
04:26
We're gonna note that we have multiple package options and we
04:29
want to make sure that we're using the to 92.
04:31
We're gonna drag this onto the screen
04:33
and we need two NPN transistors.
04:35
I'm gonna place one here and another one down into the right.
04:39
Making sure that everything is easy to access and that we don't
04:43
have everything too close together is an important step in this process,
04:46
making sure it's clean and easy to see.
04:50
The next thing that we want to add is going to be our led.
04:53
I'm gonna type in led.
04:55
And as we look through this list,
04:57
notice that some of these led s are coming from our led library.
05:00
While others are showing up in IC Power Management, for example,
05:04
we want to find led
05:06
and then in our drop down list, we want to take a look at the various package options.
05:11
Now, as we scroll through, if we don't see the correct package option,
05:14
we need to make sure that we move on and we find the correct led that we need.
05:19
In this case, I'm gonna change the filter
05:22
and I'm gonna turn off the all libraries looking just in the led library.
05:26
Now, as we look in the led library,
05:28
we're going to go to our drop down list and just
05:31
take a look at the package options that we have.
05:33
In
05:33
this case, we want to use a round five millimeter led and
05:37
we're going to drag this onto the screen
05:39
using our right mouse to rotate it 90 degrees
05:42
and we'll place it in the upper right hand corner.
05:46
Next, we want to add a few connectors.
05:48
The connectors are gonna be in our connector library
05:50
and we want to use what's called AJ ST connector.
05:54
And once we look through the JST list,
05:56
note that there are several here and navigating through the various options will
05:60
help you identify the different nomenclature
06:02
in the component descriptions and names.
06:04
Now, we're looking for a four pin connector.
06:07
So we're going to select the B four B version
06:09
noting that there are no other variants or other options.
06:13
So we'll drag this into the screen.
06:15
We're gonna place one of them on the right hand side and then we'll use the
06:18
middle mouse button to mirror this and place the other one on the left hand side
06:22
and select done or hit escape on the keyboard.
06:25
We still need to add a couple of resistors as well as power and ground symbols.
06:30
So for this, we'll clear out our filter, go back to all libraries
06:34
and we want to start by selecting V plus.
06:37
Now V plus is our voltage and we're gonna drag this onto the screen,
06:41
placing one above our left hand JST connector giving it the 12 V value.
06:47
And then we're gonna place a second one here right next to our voltage regulator,
06:52
we'll hit escape.
06:53
And the next thing we want to look for is ground.
06:56
We're gonna use GND.
06:57
We'll select the first ground from our tutorial library.
07:00
We'll drag it onto the screen and we'll place it here
07:03
giving it a value of GND.
07:06
Then we're gonna ground our voltage regulator.
07:08
We're gonna ground each one of the transistors and we also need to ground our led.
07:13
We'll place a ground symbol over here and our output connector.
07:18
The next thing we need are a couple of resistors.
07:20
Now, the resistors can be found a few different ways.
07:23
These are going to be in our tutorial library and
07:25
I'm gonna search for them by using R dash us
07:29
for R dash us. Notice on the right hand side, we have a couple of options.
07:33
There are two through hole resistors here and
07:36
we're gonna be picking the 7.2 millimeter pitch.
07:40
We're gonna drag this onto the screen.
07:42
We're gonna have a resistor for the input of the first NPN transistor.
07:46
The input for the second,
07:48
we're gonna have one for our led
07:51
and then we're going to use the right click to rotate our resistor.
07:55
We're going to place one above this NPN transistor leaving a little
07:59
bit of space and one above this one here as well.
08:01
Hitting escape to get off of our tool.
08:04
Now that we've got everything placed on the screen,
08:06
we can begin connecting them together with what's called a net
08:10
on their connect menu.
08:11
We'll select net or use R on the keyboard and we'll start by
08:14
selecting and placing a net between our JST connector and 12 volts.
08:19
We'll do the same thing over here for our voltage input to our voltage regulator.
08:23
And then we'll also connect our ground
08:26
as we take a look at some of these other components.
08:29
We're gonna go from PIN two on our JST.
08:32
We're gonna left click to have a jog in our net and then we're gonna left click again
08:37
to place it as our first resistor.
08:39
We're gonna do the same thing over here keeping everything fairly similar.
08:44
We left click and then we'll click here to end that one.
08:48
We're gonna connect the resistors to the top of our NPN transistors,
08:52
we'll connect our ground,
08:53
we'll go from our led to ground
08:55
and then we need to go from our voltage output on our voltage regulator
08:60
all the way over to our third resistor for our led.
09:03
And then we're going to have a couple of points where we come off of this,
09:07
of our five volts
09:08
will come down
09:09
and we'll take this five volts directly into this resistor
09:12
will come down and take it into this resistor.
09:15
And then we also need to take it out to pin one.
09:18
So just to the right, we'll go down
09:20
and we'll work our way over to pin one.
09:24
Also note that we need to pull voltage between the resistor and the NPN transistor
09:29
because we are using this as somewhat of a switch or switching between ground.
09:33
So when the voltage goes low, we know that we have a signal on the input side.
09:38
So we're gonna connect from here to pin three
09:41
and we need to do the same thing for this one here.
09:43
Now, everything so far has been fairly easy to connect and clean,
09:47
but now we need to jump a few wires.
09:49
What we're gonna do is we're gonna make our way straight across
09:53
left click and make our way down. We left click again and over to pin two,
09:58
we're going to hit escape. And now everything has been connected
10:02
oftentimes when we begin to lay out a schematic,
10:04
it can be very easy to get things in a situation where
10:07
we have a lot of points that are jumping over other nets.
10:11
You want to make sure as you look at your own schematic that the green dots
10:15
or intersection points are only where you need
10:17
your nets to be connected to other nets.
10:20
You can reposition these at any point in time, moving symbols
10:23
and moving nets around just to make things a little bit more clean and easy to read.
10:28
Now that we have everything laid out.
10:30
The last step in our process is to define the values for our resistors.
10:35
We can do this a couple of different ways.
10:37
But the main option that we're gonna take a look at is
10:39
under modify and selecting value or using V on the shortcut keys.
10:43
We're gonna select the first resistor and we're gonna give this a value of one K
10:49
we're gonna select OK.
10:50
And we'll do the same thing for R two giving this a value of one K.
10:55
The next one that we wanna select is R four and this one is gonna be 4.7 K.
11:00
We're gonna select R five. This will also be 4.7 K
11:05
and R three is gonna be 100 and 20 ohms.
11:09
This is gonna allow us to add and store those values on each of those components.
11:14
So that way when they're shown on a parts list or a bill of materials,
11:17
when we manufacture a board,
11:19
we'll know exactly which resistor gets which value.
11:22
Note that we can expand the inspector,
11:25
we're gonna hit escape to get off of a value tool and select resistor three.
11:29
Notice that when we select resistor three, it's shown as the name R three
11:34
and it shows its component and all the way in the bottom, it shows its value
11:38
inside of this value category. We could also make changes to its overall value.
11:42
If we wish. In
11:43
this case, we want to leave it at 100 and 20 ohms.
11:46
But the inspector is a great way to
11:48
also add additional detail such as changing the name
11:51
or some of the description or properties of various components.
11:55
Not all values can be changed and not all components
11:58
or symbols will have available options to change those values.
12:02
You can push or override some values if you wish.
12:05
But in most cases,
12:06
resistors and capacitors are going to be main
12:09
components that you are adding those values to
12:12
at this point. Let's make sure that we have saved our schematic.
12:15
We're going to call this one, our PC B
12:18
module schematic.
12:20
And once this is saved, we can go ahead and move on to our next step.
