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. |
12:11 | Annotation of circuit schematic. |
12:15 | Try the following Assignment- |
12:17 | Place component 'Inductor' on EESchema using component selection window. |
12:24 | Explore shortcut keys 'a', 'x' and 'y'. |
