WEBVTT 00:00.300 --> 00:07.050 Let's now add the LCD display screen to our second and first, I'm going to do this with the simulation 00:07.050 --> 00:13.950 and think again, as always, and then show you how to do this with the final Secrett on the real hardway. 00:14.490 --> 00:19.110 So we're going to start from the ultrasonic sensor here. 00:19.110 --> 00:20.550 I'm going to duplicate this. 00:24.130 --> 00:26.450 So here we already have three. 00:26.620 --> 00:34.930 It is that we going to keep we have the push button, the button and the infrared sensor, so we are 00:34.930 --> 00:40.890 going to leave those components here and we are going to add the LCD so you can take LCD here. 00:41.410 --> 00:49.300 And this is the LCD 16 time to get a click here and I can plug it. 00:50.260 --> 00:53.380 Actually, I can just put it there. 00:54.250 --> 00:56.100 Let's put it let's put it here, OK? 00:58.520 --> 01:05.180 So here on The Real Secrets, this we will have a bunch of different Holsey, different things, we 01:05.180 --> 01:08.360 are going to connect them in along like this on the circuit. 01:08.750 --> 01:15.800 But for the simulation, it would be easier just to put it on the side and then just to plug it directly. 01:16.160 --> 01:20.390 And the pins we are with the brain. 01:21.170 --> 01:22.540 So we have a few. 01:22.550 --> 01:26.450 As you can see, you have a few different pins here and that's quite a lot. 01:26.450 --> 01:29.820 But let's just cut them one by one. 01:30.320 --> 01:32.990 So let's go from left to right. 01:33.020 --> 01:35.690 OK, first you have Genndy. 01:36.080 --> 01:38.750 So Genndy, that's quite obvious. 01:38.750 --> 01:42.480 We're going to plug it to Genndy, so I'm going to plug it on the line here. 01:42.890 --> 01:47.200 Let's put it like, OK, make sure it's connected to the Jindalee. 01:47.930 --> 01:53.960 The second one, this is is connected to five balls in. 01:54.170 --> 01:54.570 Right. 01:54.620 --> 02:05.240 OK, we have first one ground five volt and then v0 v0 is that you can see for the contrast and we are 02:05.240 --> 02:10.870 going to need to tune the contrast here with the potential metal. 02:11.420 --> 02:14.330 So what I'm going to do is I'm going to remove that wire here. 02:14.690 --> 02:19.100 So now the Button Schmitter will not be connected anymore to an analog pin. 02:19.430 --> 02:25.400 We are going to connect the potential return to the pin v0. 02:25.940 --> 02:27.550 That's pretty blue again. 02:29.190 --> 02:35.780 So to the pin this on the LCD display screen and I'm going to show you later why we need that potential. 02:36.690 --> 02:37.680 So the button should matter. 02:37.710 --> 02:44.640 You still have one leg which is connected to ground, the other leg on the opposite side connected to 02:44.910 --> 02:49.660 Five-fold and in the middle pin connected to the zero. 02:50.370 --> 02:57.050 Then we have our S. So we're going to plug this to a digital beam. 02:57.180 --> 03:03.060 But actually, I'm going to plug it not to a digital piñon, going to plug it to an analog pin. 03:03.690 --> 03:06.720 And let's see a five. 03:09.950 --> 03:16.130 OK, because later on, I'm going to use many of the digital pins for the rest of the pins here and 03:16.130 --> 03:17.270 for other components. 03:17.450 --> 03:24.620 So when I was talking about analog pins, I told you that there can be very useful if you run out of 03:24.620 --> 03:25.400 digital pins. 03:25.440 --> 03:27.720 OK, so that's a case here. 03:27.770 --> 03:29.510 OK, that's an example I'm showing you. 03:29.780 --> 03:31.470 We're going to use all those pins here. 03:31.520 --> 03:35.960 I don't want to use PIN number 13 because this is the pin for the built in LG. 03:36.380 --> 03:39.680 And I also want to keep the pin number zero and one three. 03:39.980 --> 03:42.200 So I'm simply going to put. 03:43.470 --> 03:47.990 This has been to a five and just use a five as a digital. 03:48.770 --> 03:52.610 Now the RW, you are going to plug it to ground also. 03:53.120 --> 03:56.400 So let's put it here like. 03:57.430 --> 03:58.000 This. 04:02.070 --> 04:12.930 That's OK, so other value to ground and then e we go to another digital thing and actually I'm going 04:12.930 --> 04:15.060 to use a. 04:15.690 --> 04:17.030 So let's put it here. 04:17.370 --> 04:19.650 I'm going to use an analog. 04:21.450 --> 04:23.250 Let's use A for. 04:26.650 --> 04:29.230 It's politics, it's the ink. 04:29.740 --> 04:37.840 OK, so Genndy to e you have all the things that are collected for this and then we are not going to 04:37.840 --> 04:42.220 connect D.C. We are going to create one, two and three. 04:42.220 --> 04:43.810 We are going to start at four. 04:44.230 --> 04:48.960 OK, and the thing for the defore, we are going to connect it here. 04:48.970 --> 04:54.100 I'm going to use the digital pin number six. 04:56.250 --> 05:02.370 Yep, let's use six, let's put a different color it to was a. 05:03.950 --> 05:07.370 Is this OK, this wire is for the president and I'm going to. 05:08.560 --> 05:09.130 This. 05:11.490 --> 05:16.890 So it can start to look quite messy, but if you use different colors, that should be fine and just 05:16.950 --> 05:19.680 like one way at a time and you shouldn't have any problem. 05:22.730 --> 05:28.580 So did before in PIN number six and then five will be on PIN number seven. 05:30.170 --> 05:36.390 OK, let's get green and then be six on PIN number eight. 05:39.880 --> 05:50.920 The Brown, for example, DBE seven would be on PIN number nine, and it's changed to color also orange, 05:52.300 --> 05:52.900 yellow. 05:55.080 --> 06:00.300 All right, so you can to we have many of the digital pins that are occupied now and then you have two 06:00.300 --> 06:02.240 more pins here, you can see. 06:03.050 --> 06:14.660 And so this first one, we are going to connect it to five volts, but with a racist or so per store, 06:15.330 --> 06:17.130 I'm going to register here. 06:17.760 --> 06:19.940 I'm going to put it outside of the circuit. 06:19.950 --> 06:21.570 Actually, that's not a problem. 06:22.260 --> 06:22.800 Let's. 06:24.290 --> 06:33.830 It's like this, and this will be a two hundred and twenty point case, so right, right and wrong. 06:34.910 --> 06:41.150 And this goes to that and this goes to the. 06:42.750 --> 06:45.270 This line, OK, let's make this. 06:46.750 --> 06:47.620 That'd be nice. 06:48.040 --> 06:48.700 OK. 06:49.870 --> 06:52.210 And let's put this in red. 06:55.070 --> 07:01.520 OK, so this is an entity that basically will power on the screen. 07:01.550 --> 07:03.740 OK, so we have light on the screen. 07:03.740 --> 07:05.530 We can see what's written on the screen. 07:05.900 --> 07:11.900 So basically you need to plug one leg of the entity, OK, to here to Five-fold because it's always 07:11.900 --> 07:16.700 going to be on using a 220 on resistor and the last. 07:18.730 --> 07:23.080 Then we are going to play it to the ground, so it's. 07:24.240 --> 07:27.780 This and play it to with black. 07:29.670 --> 07:37.950 All right, and that's it for the LCD screen, so you have and can see three more connections to ground, 07:37.950 --> 07:41.670 two more connections to D.C. and then you use different digital pins. 07:42.000 --> 07:44.910 And also I use analog pins as digital pins. 07:45.570 --> 07:54.060 So quick recap first, from left to right, Genndy goes to ground and this is he goes to Five-fold v0 07:54.330 --> 07:56.880 goes to the spin of the data from the product. 07:58.470 --> 08:10.140 Up is goes to in a five hour W goes to the ground, it goes to a four and then zero one, two, three 08:10.140 --> 08:10.950 not connected. 08:11.580 --> 08:19.050 And you are going to connect the deep four to pin number six, the five to pin number seven, the six 08:19.050 --> 08:24.160 to pin number eight decision to pin number nine and then you have an NDA. 08:24.160 --> 08:33.720 So the first on the left first thing is going to Five-fold with a 220 on register and the last one is 08:33.720 --> 08:34.700 going to the ground. 08:34.770 --> 08:35.280 Also. 08:36.320 --> 08:36.800 All right. 08:38.110 --> 08:39.840 The secret is not complete. 08:41.240 --> 08:47.600 All right, and this is the real how to a secret, so you can see now I have plugged the LCD screen 08:47.840 --> 08:51.560 online, so make sure you don't play it on a minus or a plus nine. 08:51.630 --> 08:58.790 OK, make sure you connect it directly on the breadboard with each pin connected to a different line 08:58.790 --> 08:59.230 of the red. 08:59.720 --> 09:03.600 OK, so you can see I've put it there, OK, just near the bottom. 09:04.190 --> 09:13.490 So we have well of course I have also disconnected original first you can see here the thing is that 09:13.490 --> 09:20.990 the name using the pin may be different from the name you see on the simulation, but the other is exactly 09:20.990 --> 09:21.520 the same. 09:22.010 --> 09:29.780 So you have first VSS that you're going to connect to the ground with this black wire, then you have. 09:31.060 --> 09:39.110 This is this idea that you going to fight, what with this small right way and then you have zero pin. 09:39.140 --> 09:45.690 So you can see here put on Schmitter before that being was connected to an analog pin right there. 09:46.000 --> 09:52.570 But now I have removed this connection and cut the connection from the data being of the potentiator 09:52.960 --> 09:55.740 to the V0 being here. 09:56.500 --> 10:02.830 Then I have the power as being as being the we're going to a five. 10:04.730 --> 10:15.690 The next one is RW, RW going to the ground and then we have it going to a four right there. 10:16.670 --> 10:19.480 So that's the first range of things. 10:19.760 --> 10:26.510 Now we have these are all Daewon, these three, two, three that are free and defore. 10:26.510 --> 10:28.850 So DeFore is going to be number six. 10:29.430 --> 10:38.090 OK, you can see here and then deep five, PIN number seven, the PIN number eight and the seven pin 10:38.090 --> 10:39.770 number nine. 10:40.250 --> 10:50.600 OK, so the pins here correctly connected and then we have a K, a K which are for the energy of this 10:50.900 --> 10:51.610 display screen. 10:52.010 --> 11:01.850 So the first one A I have, but as you can see that 220 cm Restall from the pin to the five volt line 11:02.090 --> 11:07.490 and then the last pin is connected to the ground with another black wire. 11:08.240 --> 11:15.560 OK, so if you just make sure you connect one thing at a time and you make sure it's correctly connected, 11:15.920 --> 11:17.570 you should not have any problem. 11:17.690 --> 11:22.910 And now your hardware setup is down and you can start to work with the LCD screen.
