WEBVTT 00:00.240 --> 00:06.750 The breadboard is a super useful tool to prototype any secrets with your Arduino without a breadboard, 00:06.900 --> 00:12.500 you would have to sodor all components in a secret so they can connect between each other. 00:12.720 --> 00:19.650 And then again, for each modification you make on the circuit, as you can guess, this would quickly 00:19.650 --> 00:22.040 be messy and unreliable. 00:22.350 --> 00:28.170 The breadboard allows you to connect all your components with your Arduino and between each other in 00:28.170 --> 00:30.150 an easy and practical way. 00:30.540 --> 00:34.580 Then modifying the circuit can be as short as a few seconds. 00:35.160 --> 00:37.560 So how does a bride both work? 00:38.020 --> 00:44.670 Let's have a look with the Tinker CAD simulation here and then I will show you the real physical Brainbow. 00:44.940 --> 00:52.220 So on, Dinko, you simply go on the component on the right here and you can start to search for Bridel. 00:52.890 --> 00:55.740 You have so you have different kinds of breadboard. 00:55.980 --> 01:01.950 Basically, they are all the same, can have a small one and breadboard. 01:01.980 --> 01:09.190 So this is the standard one standard size and this is half the size of a normal Brainbow. 01:09.780 --> 01:16.050 So as you can see, there are many holes here where you can connect wires and components. 01:16.470 --> 01:22.470 And what you need to know is that underneath the surface there are some metallic wires between some 01:22.470 --> 01:27.300 of the holes of the board which make them electrically connected. 01:28.580 --> 01:35.480 So the most important thing to learn here is how those bones are connected between each other and you 01:35.480 --> 01:39.320 will see it's actually quite simple and we're the dingo get simulation we get. 01:39.470 --> 01:42.630 And there is good and simple overview to understand that. 01:42.650 --> 01:47.990 So first of all, you can see that here you have two lines. 01:47.990 --> 01:51.540 So you have a plus and minus line or it can be red or blue. 01:51.920 --> 01:54.560 OK, you have the same on the small breadboard. 01:55.650 --> 02:02.680 And those two lines will be used for so the plus are the right one would be used for power supply and 02:02.740 --> 02:07.170 minus all the blue dark one will be used for the ground. 02:07.320 --> 02:13.560 So the ground of the secret is basically a common point between all of your components. 02:13.800 --> 02:15.300 And that's very important. 02:15.300 --> 02:19.580 So you can have a reference point for any voltage in your circuit. 02:19.980 --> 02:26.820 So as you can see here, I'm going to zoom a little bit when I choose one of the dots here. 02:27.450 --> 02:31.670 You can see all the dots here connected in the Green Line. 02:31.800 --> 02:32.980 So are the same. 02:33.300 --> 02:40.510 That's so if I connect something here, if I connect something here, that's the same. 02:40.770 --> 02:46.890 OK, so everything you connect on this line will be connected to all of the other components on this 02:46.890 --> 02:47.130 line. 02:47.460 --> 02:50.780 And the same happens for this line here. 02:51.060 --> 02:55.680 But as you can see, the first and the second line are independent. 02:56.130 --> 03:04.010 So one line foreground, one line for power supply and you have the same here, power supply and ground 03:04.140 --> 03:10.290 and on the small breadboard, that's the same ground power supply here and ground supply here. 03:11.150 --> 03:19.130 And then you have many different lines of dots, and as you can see here, the dots are connected vertically 03:19.130 --> 03:19.410 here. 03:20.360 --> 03:28.100 So on a normal breadboard, you have about 60 something different lines where you can connect components. 03:28.370 --> 03:33.920 So if you're going to get the components here on that point, that would be the same as here. 03:33.950 --> 03:38.300 So if you connect to components on that point, they would be connected together. 03:39.020 --> 03:43.460 If you connect one component here and one component here, they are separate. 03:44.560 --> 03:51.050 And you can see we have all these parts here and all these parts on the top is exactly the same. 03:51.070 --> 03:55.680 OK, but this as you can see here, we have five connected dots. 03:55.800 --> 03:58.920 OK, those are five different connected dots. 03:59.440 --> 04:04.910 And we've all of those dots here, you would be able to create any secret you want. 04:05.440 --> 04:13.270 So the most important thing to remember is you have a ground line, a power supply line, and then many 04:13.270 --> 04:17.200 different lines that you can use for your components. 04:17.440 --> 04:24.280 If you have any doubt, just go to the tinker card and use a breadboard from the components and you 04:24.280 --> 04:28.060 will see it's very easy to check what is connected to what. 04:29.530 --> 04:34.870 So here is my physical breadboard, so maybe you have something similar. 04:35.170 --> 04:38.820 So this is the exact same thing as I showed you on Temko. 04:38.830 --> 04:40.210 Can you have here? 04:40.220 --> 04:42.300 So we have two lines. 04:42.310 --> 04:45.240 We have the plus line and the minus line. 04:45.610 --> 04:49.690 So all the dots in this line are connected together. 04:50.110 --> 04:53.360 All the dots in the minus line are connected together. 04:53.620 --> 04:56.800 You have the exact same on the top you need to. 04:57.340 --> 05:03.880 And then we have many different lines here that you will use to connect your components. 05:03.880 --> 05:11.650 So, for example, on line here, 45, all of the five dots that you see here are connected together 05:12.400 --> 05:13.930 and well, that's pretty much it.
