WEBVTT 00:00.180 --> 00:03.510 And let's add the photoresistor essential to our secret. 00:04.010 --> 00:10.830 I'm going to start from the previous Sigrid's, which contains I asso infrared remote control that I'm 00:10.830 --> 00:12.240 going to duplicate. 00:15.170 --> 00:20.030 OK, and let's name it photo array, the store. 00:22.080 --> 00:27.390 All right, so that is the last thing we are going to add to our circuit so you can search here on the 00:27.390 --> 00:33.120 right in the least photo array store, you would find this should look like this. 00:33.480 --> 00:34.410 They can take it. 00:34.710 --> 00:40.800 And you can see we just have two things he tinker, can I have terminal one? 00:40.810 --> 00:41.400 Terminal two. 00:42.000 --> 00:50.460 So what I'm going to do simply I'm going to take this photoresistor and put it on so each leg of the 00:50.460 --> 00:53.340 photo result on a different line. 00:53.370 --> 01:00.240 OK, on the breadboard so far, I photoresistor all just like for a still actually there is no plus 01:00.240 --> 01:01.550 or minus side. 01:01.560 --> 01:04.740 OK, the direction of the component here doesn't matter. 01:05.010 --> 01:09.420 So what we are going to do first connect to the ground and to connect to the ground, we are going to 01:09.420 --> 01:20.160 take one leg of the photoresistor and first, but also restore and we take this and this will be a 10 01:21.210 --> 01:21.820 resistance. 01:21.840 --> 01:24.590 So just like the one we used for the push-Button. 01:26.350 --> 01:33.640 So this is brown, black and orange with a full bench crystal, and I'm going to put this here. 01:35.020 --> 01:43.390 So I can one leg of the photoresistor to the stool and then the other side to the ground, which is 01:43.400 --> 01:52.200 deadline and back and then the other side of the photoresistor, I'm going to connect it to five volt 01:52.960 --> 01:53.490 with Ray. 01:54.330 --> 02:01.110 So as you can see, the setup is really quite similar to the setup of the pledge, but we have one leg 02:01.110 --> 02:06.540 connected to Five-fold and the other one connected to the ground via a 10 kilometer storm. 02:06.630 --> 02:09.930 And now how are we going to get some data from this sensor? 02:09.960 --> 02:17.100 Well, we need to connect one piece of the arena to one leg of the photoresistor. 02:18.180 --> 02:19.500 What kind of do we need? 02:19.500 --> 02:26.040 We need an analog pin because we are going to read an analog value from the photoresistor. 02:26.310 --> 02:31.650 Actually, photoresistor is quite similar to a potential where the difference is that potentiator. 02:31.890 --> 02:38.730 Well, you are going to manually move the button here to change the value you read with analog pins 02:39.420 --> 02:39.680 here. 02:39.690 --> 02:42.810 The value would change depending on the luminosity of the room. 02:43.080 --> 02:49.830 So what I'm going to do, I'm going to take here once I'm going to take the leg, which is connected 02:49.830 --> 02:58.380 with the resistance on this line, going to take a wire to wire here and then go to. 03:00.130 --> 03:07.630 Analog being, let's say, analog being number zero eight zero, let's change the color. 03:09.190 --> 03:09.670 To. 03:10.790 --> 03:16.280 Arrange OK, looks good, you can a that looks good. 03:17.390 --> 03:25.110 So here I got a pin, so a zero connected to that pin of the photoresistor. 03:25.610 --> 03:34.100 So to recap, one of the pin here connected to five-fold the other pin with one wire going to a zero 03:34.340 --> 03:37.870 and then irresistable connected to Iran and that's it. 03:38.960 --> 03:42.520 And I'm just going to show you how you can interact with these sensor. 03:42.800 --> 03:44.180 So it's the same thing. 03:44.190 --> 03:48.620 Every other sensor, you just click on it and you can see you can set the luminosity here. 03:49.940 --> 03:55.130 So here you will get the max value, here you will get the lowest value. 03:55.460 --> 03:58.870 OK, so that's how you can fake the luminosity that. 03:59.930 --> 04:02.170 And here is the real how to set up. 04:02.210 --> 04:09.130 So, again, I have disconnected the first and then you can see the photoresistor is right here. 04:09.410 --> 04:13.650 And actually for this setup, I have just used one wire. 04:13.720 --> 04:14.840 OK, why is that? 04:14.850 --> 04:22.400 Because I have plugged directly one leg of the photoresistor to five volt line, as you can see here. 04:22.430 --> 04:29.690 So the right one, then another leg to one line of the breadboard and then from this line of the breadboard. 04:29.700 --> 04:36.260 So I have my wire here connected to a pin, number eight zero of them. 04:37.040 --> 04:45.410 And then I have one tenkile on resistor connected again from this line to directly the ground to here 04:45.410 --> 04:51.490 by directly plugging the components to five volt and directly plugging the register to the ground. 04:51.500 --> 04:53.120 I can save two wires. 04:53.570 --> 04:54.040 Right. 04:54.890 --> 04:56.930 And well, that's pretty much it for the circuit.
