| 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 |
| 12:05 | In this tutorial we learnt, |
| 12:07 | To use EESchema in KiCad for creating circuit schematic |
| 12:11 | Annotation of circuit schematic. |
| 12:15 | Try the following Assignment, |
