Time Narration
00:01 Dear friends, Welcome to the Spoken Tutorial on “Designing circuit schematic in Kicad”.
00:08 Let us 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 the 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- Go to the top left corner of ubuntu desktop screen.
01:08 Click on the first icon i.e the Dashhome.
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 the 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 the 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 zoom 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 your 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, known 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 the 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-annotated 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 the 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.
12:05 In this tutorial, we learnt-
12:07 To use EESchema in KiCad for creating circuit schematic.
