Time Narration
00:01 Welcome to the spoken tutorial on “Designing circuit schematic in Kicad”
00:08 Let us now see the steps involved in PCB designing
00:12 First step is to create schematic for the desired circuit.
00:16 Second step is to generate netlist.
00:19 Third step is to map components with corresponding footprints.
00:22 And fourth step is to create board layout for the circuit.
00:27 In this tutorial we will learn first step, that is,
00:32 Creating a schematic for the desired circuit.


00:35 We are using Ubuntu 12.04 as the operating system.
00:40 With KiCad version 2011 hyphen 05 hyphen 25 for this tutorial.
00:49 Basic knowledge of electronic circuits is a pre-requisite for this tutorial.
00:56 We will use Astable multivibrator as an example circuit for this tutorial.
01:04 To start KiCad,
01:05 Go to top left corner of ubuntu desktop screen.
01:08 Click on first icon i.e the Dash home.
01:12 In the search bar type 'KiCad', and press Enter.
01:19 KiCad main window will appear on the screen.
01:22 Note that in Ubuntu 12.04, the menu bar of KiCad appears on the top panel of Ubuntu desktop.
01:30 To start a new project, click on File and then click on New.
01:35 Give a name to your project. For example, project1.
01:42 Note that project is getting saved with .pro extension
01:47 Let me resize this window for better view
01:52 Notice where your project is getting saved and change the directory if needed.
01:58 Click on Save.
02:01 Circuit schematics are made in KiCad using EESchema.
02:06 Let me show you how to start EESchema in KiCad.
02:10 The first tab in the top panel of KiCad main window is called as EESchema or schematic editor
02:19 Clicking on EESchema tab opens the schematic editor.
02:23 An Info dialog box will appear saying it cannot find the schematic.
02:28 Click on Ok.
02:32 We will create circuit schematics here.
02:35 Go to right panel of EESchema window.
02:38 click on Place a component button.
02:42 Now click on the blank EESchema window.
02:46 The component selection window will open up.
02:49 Now we will place 555 timer IC schematic in the EESchema window.
02:56 In the Name field of component selection window, type 555 and click on Ok.
03:05 It will show the search result as LM555N.
03:11 Select this result and click on OK.
03:14 The component’s schematic will appear on the EESchema window.
03:19 It would be tied to your cursor.
03:22 Place the component at the center of the screen by a single click.
03:27 To zoom in and out for better view use the scroll button of your mouse.
03:35 Keep Cursor on Component which you want to zoom in and zoom out.
03:39 You can also use F1 and F2 keys to zoom in and zoom out, respectively.
03:46 You may or may not see the VCC and GND i.e. the ground terminal on the 555 IC.
03:56 If you do not see it, go to the left panel of EESchema window.
04:00 Click on the Show hidden pins button.
04:04 Now we will place a resistor in the EESchema window.
04:09 The Place a component option was previously selected by us.
04:13 Hence, simply click on EESchema and you will see the component selection window.
04:21 In the name field, type r and click on OK.
04:26 Resistor schematic will appear on EESchema which will be tied to cursor.
04:32 Place the resistor somewhere on the EESchema by a single click
04:37 We need two more resistors.
04:39 We can get the two resistors using the Place a component button.
04:42 But since we already have a resistor, let us see how to copy a component.
04:48 To copy a component, right click on the component and choose Copy Component.
05:01 A copy of the component will be tied to your cursor.
05:05 Place this resistor somewhere on EESchema by a single click.
05:11 This can also be done more quickly using the keyboard shortcut c.
05:16 For this, keep the cursor on the component and then press c.
05:22 Again it will be tied to your cursor.
05:27 Click once to place it.
05:30 A list of shortcuts can be obtained by pressing Shift and ? (question mark) key.
05:36 Here is the list of keyboard shortcuts.
05:40 Close this window.
05:43 Click on EESchema window to open the component selection window.
05:49 Next we need two capacitors, electrolytic and ceramic.
05:53 Type cp1 to add electrolytic capacitor and click OK.
06:00 Type c to add ceramic capacitor and click OK.
06:06 We also need a Light Emitting Diode, know as LED.
06:10 In component selection window type led and click on OK.
06:17 Now we need a power supply i.e.Vcc and Ground terminals.


06:22 On the right panel of EESchema, click on Place a power port button.
06:29 Click once on the EESchema to open the component selection window.
06:34 Click on List All button and you will see a list of various power notations.
06:40 Choose +5V (plus 5 volt) and click on OK.
06:48 Place the component by single click on the EESchema window
06:52 Similarly, to get the ground terminal,
06:54 choose ground from the list and click on OK
07:01 Let me choose the ground terminal
07:08 We also need a connector to connect the external power supply
07:14 Click on the EESchema to open the component selection window.
07:19 Click on List All button and you will see a list.
07:24 Choose conn option and click on OK.
07:31 Scroll down and choose CONN_2 from the list and click on OK.


07:41 A two terminal connector will appear. It will be tied to your mouse pointer
07:48 Click once to place it.
07:56 Now we will arrange the components, by moving them to appropriate places.
08:01 We will use the shortcut key m for moving the components.
08:04 To move a component, keep the mouse pointer on a component, say resistor, and then press m.
08:15 We will place this resistor to the right of IC 555 by a single click on the EESchema.
08:28 We will use the keyboard shortcut key r for rotating the LED and aligning it vertically.
08:40 Now we will see how to interconnect or wire the components as per the circuit diagram.
08:45 Let us start with the interconnection of components.
08:48 On right panel of EESchema, Click on Place a wire button.
08:56 We will now interconnect two resistors.
08:58 We will connect wire by clicking on either nodes of both the resistors.
09:11 Now we will connect the 7th pin of IC 555 to the wire connecting the two resistor.
09:18 Click on the 7th pin of IC 555 and then on the wire connecting the two resistors.
09:30 Notice that this will automatically form a junction which appears as a node.
09:35 I have already interconnected the components and saved it.
09:39 I will now open and use this already made schematic to save time.
09:44 I will go to file menu & click on open.
09:53 A Confirmation window opens. Click on Yes.
10:04 I will choose project1.sch from the desired directory.
10:18 Let me resize this window first .
10:22 and then I will click on open.
10:29 I will click on open.
10:33 Here is the schematic created earlier.
10:36 We would now see how to annotate components.
10:39 Annotation gives unique identification to each component.
10:43 Annotating will replace the question marks on the components with unique numbers.
10:50 On top panel of EESchema, Click on “Annotate schematic” button.
10:58 This will open the Annotate Schematic window.
11:02 In this window, keep the default configuration.
11:05 Click on the Annotation Button.
11:09 This will warn you that it will annotate only the un-annotate components.
11:13 Click on OK.
11:15 Click on the Close button on the Annotate schematic window.
11:20 Notice that the question marks on the components are replaced with unique numbers.
11:30 Click on File
11:37 and choose Save whole schematic project to save this schematic.
11:43 Click on File and choose Quit.
11:48 This will close the EESchema window.
11:50 Now go to KiCad main window.


11:53 Click on File and choose Quit
11:56 This completes the objective of this tutorial of creating circuit schematic in KiCad.
12:01 Let us summarize what we learnt in this tutorial
