WEBVTT 00:00.210 --> 00:08.130 Let's start by adding to our secrets, so then you would be able to use it with digital pens set up 00:08.130 --> 00:14.520 as input means, I'm going to show you exactly what to do in Tinker Card and then you can follow the 00:14.520 --> 00:17.160 exact same step that you do a real secret. 00:17.170 --> 00:18.480 And I will show you the results. 00:18.510 --> 00:24.770 Also, with the real secrets that we are not going to start an empty project here, we're going to use 00:24.810 --> 00:26.480 what we already had before. 00:26.490 --> 00:31.250 OK, so every time we add a new component, we are going to do it in an iterative way. 00:31.620 --> 00:35.400 So we have all the components that we have added before, plus the new one. 00:36.150 --> 00:40.700 So here what you can do here, we have our LG Sigrid's. 00:41.040 --> 00:46.920 You can click on these settings here and click on Duplicate. 00:49.850 --> 00:55.670 Now, we are not going to modify directly any secrets, we create a new one, OK, which is a copy of 00:55.670 --> 01:00.930 aready, let's name it Bush Button, OK? 01:00.980 --> 01:04.740 And we are going to get the budget done right here in this secret. 01:05.080 --> 01:11.440 So the first thing we can see is that we already have the connection between the ground of the original 01:11.450 --> 01:12.810 and the ground here. 01:13.220 --> 01:16.010 This line that we set up as the ground of the preborn. 01:17.720 --> 01:24.090 But I'm going to add the power button here on the right, and you can see here on the list of components, 01:24.090 --> 01:26.030 we already have Berbatov here. 01:26.310 --> 01:30.420 But as a to if you don't have it, you can directly search for it. 01:31.350 --> 01:37.620 I take my push button, I put it there, and then we will also need a racist or. 01:38.930 --> 01:48.550 OK, taking register and these register will be a 10 kiloton raised kilo here and then here. 01:48.980 --> 01:53.120 And as you can see, we have brown, black and orange. 01:54.320 --> 02:01.460 I'm going to make it rotate like this, all right, and that's all the components we need, plus the 02:01.460 --> 02:05.770 different wires, OK, but the wires, we are going directly to create it from the bone. 02:06.410 --> 02:08.810 That's all the components we need for the circuit. 02:10.180 --> 02:18.340 What we're going to do is take the then and place it here between the two sets of lines here on the 02:18.340 --> 02:18.970 BRADBOURN. 02:20.450 --> 02:25.810 So you have one leg here, one leg, see another one here and another one here. 02:28.430 --> 02:36.350 We are going first to connect this push button to the ground and to do that, we are not going to directly 02:36.350 --> 02:39.200 connect to the ground, but we are going to register. 02:39.750 --> 02:43.510 OK, I'm going to explain just after why we had to register here. 02:44.240 --> 02:53.540 So on this link here, you can connect one register and then connect the other leg of the register here 02:53.540 --> 02:54.430 to another line. 02:54.860 --> 02:59.750 And then I'm going to take this and connect to the ground. 02:59.760 --> 03:01.810 So make sure this is the ground line, OK? 03:01.910 --> 03:02.390 Yes. 03:02.390 --> 03:03.440 This is the ground nine. 03:05.020 --> 03:11.830 I'm going to put this in black, because this is the common ground and that's the first connection we 03:11.830 --> 03:18.820 need to know the Syrian connection is we need to connect this leg, OK, on the other side of the button 03:19.240 --> 03:22.870 to the five-fold supply of the Ardino. 03:22.880 --> 03:25.990 So we can see here we have a five world supply. 03:26.890 --> 03:35.500 And instead of just putting a wire like that to fibrotic would do this, OK, but instead I'm going 03:35.500 --> 03:37.960 to connect the five five-fold air. 03:41.340 --> 03:42.450 The plus. 03:43.410 --> 03:43.880 Line. 03:43.920 --> 03:48.040 OK, so I'm going to carry it and we'll the color, right? 03:48.060 --> 03:51.560 OK, Red is the convention for power supply. 03:51.840 --> 03:56.630 So I'm going to use the right only for power supply and not for anything else. 03:57.150 --> 04:02.850 And I recommend you do the same black and red ground and power supply. 04:03.540 --> 04:10.020 The five volt here goes directly to this line, which means that now all this line. 04:11.300 --> 04:16.670 Is connected to Facebook, and you will see in the following of these girls, we actually need to connect 04:16.670 --> 04:19.260 multiple components to the power supply. 04:19.520 --> 04:21.260 So this line will be dirigiste. 04:22.130 --> 04:31.310 So what we can do and we need to take one dot from this line, any dots and connect it to the line of 04:31.310 --> 04:38.260 the five to make sure that you don't connect it to the ground, but to the line of fire and. 04:38.270 --> 04:38.890 But it good. 04:38.900 --> 04:39.880 All right. 04:40.760 --> 04:46.760 OK, so you can see by using the different colors, red and black, we can easily make the difference 04:46.760 --> 04:48.640 between ground and five-fold. 04:48.950 --> 04:53.000 So in the future we will make much less mistakes. 04:53.240 --> 04:53.630 All right. 04:53.640 --> 04:58.960 So we have this been connected to ground we've with on this been connected to by vote. 04:59.270 --> 05:07.130 Now I'm going to take the pin, which is on the other side here of the button on this side, which also 05:07.130 --> 05:10.060 corresponds to the side of the ground. 05:10.730 --> 05:12.970 And I'm going to take one dot. 05:12.980 --> 05:17.780 So let's say this one and I'm going to connect it now to. 05:19.070 --> 05:20.230 Digital bin. 05:21.280 --> 05:22.180 No. 05:22.450 --> 05:27.610 Two, like in the square like these. 05:28.760 --> 05:30.420 OK, that's better. 05:34.220 --> 05:41.930 So with this being number two, we are going to be able to read the state of the push button and right 05:41.930 --> 05:43.670 now the secret is now finished. 05:43.670 --> 05:45.690 And just why did I? 05:45.710 --> 05:49.160 D register here connected to the ground? 05:49.910 --> 05:52.760 Because this is actually not mandatory. 05:53.150 --> 05:58.570 This register will act as what we call a pulldown register. 05:58.850 --> 06:00.530 What is a pulldown register? 06:00.670 --> 06:05.870 Well, well, you just have a curtain here and you have so ground and power supply. 06:05.870 --> 06:09.980 And then you read the state from that in the state of the button. 06:10.000 --> 06:16.850 So the voltage that is applied to the button may be floating, which means that it can be anywhere from 06:16.850 --> 06:24.800 zero to five volt and the voltage will continuously change by adding this register here connected to 06:24.800 --> 06:25.350 the ground. 06:25.670 --> 06:32.200 What we do is we force the default state of the button to be low. 06:32.210 --> 06:37.700 So to be zero volt and you could do the same thing with a pull up register. 06:37.780 --> 06:43.370 So instead of creating a register, go to the ground, you will connect it to the power supply. 06:43.370 --> 06:50.480 And then instead of using this line for the digital thing, you would use the other one and thus will 06:50.480 --> 06:55.410 describe the default state for the push button will be high five. 06:55.530 --> 06:55.790 OK. 06:56.120 --> 07:05.150 OK, so here by doing this, so we pull down resistor to zero volt when we read the stage for the push 07:05.150 --> 07:05.600 button. 07:05.900 --> 07:12.290 When the button is not pressed, we will read the state level and when the button is priced, we need 07:12.290 --> 07:19.460 to rate the state high and we don't need to worry about the voltage here floating between two numbers. 07:20.740 --> 07:27.360 All right, and this is the real hardware circuit, so make sure that you just connect the world to 07:27.370 --> 07:33.160 at least one of the two parts of the U.S. cable here just from completely. 07:33.550 --> 07:35.800 And then so we have. 07:36.760 --> 07:38.000 When do we have a secret? 07:38.500 --> 07:43.810 We have our pushbutton here, which I've collected, just like in the Tinker Get simulation game between 07:43.810 --> 07:46.970 the two parts, between the two sections of the BRADBOURN. 07:47.380 --> 07:53.740 Then I have my in my down register, which is a tentative register. 07:54.130 --> 08:02.050 But as you can see here, instead of connecting the register between this leg of the button and another 08:02.440 --> 08:09.010 line and then adding a black wire, I just directly connected the restore between the ground and this 08:09.010 --> 08:09.790 leg of the register. 08:09.820 --> 08:13.410 OK, because this is very near. 08:13.870 --> 08:15.430 I can save the wire there. 08:16.120 --> 08:26.680 Then I have added here this wire, OK, between Kinsela Five-fold, King of the Arduino and this line. 08:26.710 --> 08:34.100 OK, so I have the ground to the ground and the five volt lines are not all this line here in red. 08:34.520 --> 08:43.090 It's connected to Five-fold and I have the small wire around wire between this line and this being able 08:43.100 --> 08:43.600 to button. 08:43.870 --> 08:46.570 And finally here on this. 08:47.580 --> 08:50.290 Side, OK, which is the same side as the ground side. 08:51.000 --> 08:52.290 I have another way out. 08:52.320 --> 08:54.270 So I chose Green as well. 08:54.660 --> 08:58.110 Another wire that is connected between this bin and. 08:59.450 --> 09:01.620 He had been number two of the. 09:03.930 --> 09:10.230 All right, I know you have your attorney here and the president here and the two lines of the plus 09:10.230 --> 09:15.720 and minus line are connected respectively to the Bible and to the grand.
