WEBVTT 00:00.240 --> 00:03.950 Let's us know an LCD screen to our secret. 00:04.010 --> 00:12.080 So the screen will be super useful so we can display some text directly from the Arduino, so density 00:12.090 --> 00:14.220 we are going to use a 16 by two. 00:14.250 --> 00:17.820 OK, and well, I'm going to put it there on tin can. 00:17.820 --> 00:24.930 And then you will see that I'm going to directly plug it here on the bread board when I do the real 00:24.930 --> 00:25.350 secret. 00:25.350 --> 00:30.780 But for the just for the simulation and to show you the connections for the beans, there's going to 00:30.780 --> 00:32.760 be easier like this funnel. 00:33.180 --> 00:38.370 So you have many connectors here and let's go step by step one by one. 00:38.400 --> 00:44.040 First, you have a GNT, so ground you're going to connect to the ground line. 00:44.310 --> 00:46.210 Let's make sure that is ground light. 00:46.230 --> 00:46.530 OK. 00:47.290 --> 00:48.810 It's actually pretty, ladies. 00:50.310 --> 00:57.720 So ground is going to be black and then you have this ESI and this is you connect to. 00:58.780 --> 01:01.540 The this is your line here. 01:01.630 --> 01:09.940 Five volt line, then we have V0, V0 is going to be used to calibrate the luminosity of the screen, 01:10.240 --> 01:12.550 OK, using a potential meter. 01:12.970 --> 01:15.840 So basically here we need to also add a potent emitter. 01:16.990 --> 01:19.300 So I'm going to put it put on soumettre here. 01:20.230 --> 01:24.040 And so the potential, do you have three legs? 01:24.340 --> 01:29.350 You want to put one of the leg, for example, the left one connected to the ground. 01:30.750 --> 01:34.020 Blackwell and then the opposite one connected to. 01:35.710 --> 01:36.310 My vote. 01:37.350 --> 01:41.970 We've all read the wire and then you're going to connect this V0 here. 01:43.220 --> 01:46.570 To the middle pin of the potential middle. 01:48.770 --> 01:50.810 And but it OK. 01:52.160 --> 02:00.440 The next thing is the art has been and, well, this one, you're going to plug it in to a digital pin. 02:00.650 --> 02:06.080 But because we will not have enough digital print, I'm going to plug it into an analog pin instead. 02:06.440 --> 02:15.380 So I'm going to plug it to a phone because, well, you can use actually analog pins as digital pins. 02:15.830 --> 02:22.610 So if you ever run out of digital pins, just use an analog instead and into just use it as a digital 02:22.610 --> 02:31.940 pin, and it's changed color green and then R.W other where he was going to be connected to the ground 02:33.230 --> 02:37.260 with a black wire and for enable. 02:37.880 --> 02:44.720 He is going to a five the same reason as for a spin. 02:45.050 --> 02:47.330 Let's use a different color, for example, purple. 02:47.930 --> 02:54.010 We're going to use this as a digital pin because we won't have enough digital pins here on the secret 02:54.020 --> 02:55.010 for all the components. 02:55.610 --> 02:59.780 Then you have the zero, one, two and three. 03:00.320 --> 03:04.040 You're not going to put anything for those things here. 03:04.280 --> 03:09.920 And then before default, we're going to plug it to the digital pin number two. 03:11.150 --> 03:14.390 So let's use another color for the yellow. 03:15.870 --> 03:20.010 OK, DeFi is the next one two digital pin number three. 03:21.860 --> 03:22.970 Let's use. 03:24.790 --> 03:37.780 Grass and then six to digital in full, so we just follow, we think, the seven to. 03:39.780 --> 03:41.690 Digital been five, all right. 03:41.820 --> 03:42.680 Use a range. 03:43.800 --> 03:44.460 OK. 03:44.910 --> 03:47.120 And then we have energy, so we have to. 03:48.540 --> 03:53.400 The first one is going to be connected to five volt, but with a variety store. 03:54.210 --> 03:57.790 So that's going to be the energy of the LCD screen. 03:57.820 --> 03:58.070 OK. 03:58.140 --> 04:03.660 Because when you use actually and it is here, you can see we use arises also. 04:03.750 --> 04:05.310 That's the same reason here. 04:05.580 --> 04:15.300 I'm going to add every store here to 120 on, and I'm just going to connect it between. 04:16.600 --> 04:23.860 Yet this reaction on the LCD, we read wire and then connected to the. 04:25.690 --> 04:32.590 He line the five volt line, and then we have that one connected to the ground. 04:34.240 --> 04:34.700 All right. 04:36.400 --> 04:43.180 One thing to make sure that you don't do is so don't connect anything to those beings here. 04:43.540 --> 04:45.130 Digital been zero and one. 04:45.520 --> 04:46.060 Why is that? 04:46.060 --> 04:48.100 You can see we have Alex and Tina. 04:48.520 --> 04:51.970 So those pins are also actually used for cellular communication. 04:52.210 --> 04:55.870 So when later on, we use cell communication with the USB cable? 04:56.110 --> 05:00.430 If you have anything plugged here, you're going to have some weird behavior. 05:00.460 --> 05:05.380 OK, so you're going to have some arrows on the same communication and maybe also on the components 05:05.380 --> 05:08.470 that you use on those pins to leave those pins and. 05:09.790 --> 05:16.120 And here is the secret with the LCD screen, so this can look a bit messy, but well, actually, if 05:16.120 --> 05:20.530 you just follow all the steps that I did on Tinker, you should not have any problem. 05:20.740 --> 05:26.030 So I have blinked as you see the screen directly on one of the line here. 05:26.050 --> 05:32.280 So each should each pin each leg of the LCD on a different line. 05:32.290 --> 05:32.620 OK? 05:32.800 --> 05:35.770 This is not connected on the blue. 05:35.770 --> 05:36.730 All of the red line. 05:36.740 --> 05:37.810 This is connected here. 05:38.500 --> 05:45.580 Separated lines on the right book and then you can see each connection here. 05:45.880 --> 05:47.590 So I have the first one. 05:48.730 --> 05:50.530 Maybe you will have lots of different names. 05:50.920 --> 05:53.650 OK, on the on the LCD. 05:53.650 --> 05:59.260 So you have, for example, as we did at the end, I have eight and Kate. 05:59.530 --> 06:04.240 So the name can be different, but the other is going to be the same as what I did before. 06:04.570 --> 06:06.640 So the first one is connected to the ground here. 06:07.780 --> 06:12.910 The second one she does right away is connected to this, you see. 06:13.450 --> 06:15.430 And then the third one is V0. 06:15.430 --> 06:18.100 So v0 is he connected? 06:18.520 --> 06:25.510 So this blue connected to the output been off the potential meter and the potential meter also has. 06:25.870 --> 06:32.740 So for the two extreme legs, a black way out to the ground and the right wire to this issue. 06:33.310 --> 06:35.680 After that, we have the. 06:37.050 --> 06:48.480 R s R s, which is going to take you to a fall and then we have the RW RW connected to the ground here 06:48.510 --> 06:55.470 with this black wire, the E for Enable connected to A5. 06:56.430 --> 06:59.850 And then we have nothing for zero until three. 07:00.420 --> 07:08.210 And then you can see D4 device connected to digital pin number two and then D5 to digital P three. 07:08.850 --> 07:15.390 The six two digital twin full and the seven two digital pin number five. 07:15.960 --> 07:23.220 At the end, we have so for the A here, which is basically the positive side of the energy of the screen. 07:23.550 --> 07:33.780 I have one 220 Ohm Restall connected from here to a different line, and then this red wire connected 07:33.780 --> 07:41.910 to the plus lanky and the bright block and the last connection here is a black way up to the ground. 07:42.540 --> 07:42.960 All right. 07:43.590 --> 07:45.690 And that's it for the LCD screen.
