WEBVTT 00:00.180 --> 00:07.320 And this is the solution to a previous activity where you need to set the brightness of the energy directly 00:07.320 --> 00:08.570 from the potential emitter. 00:09.090 --> 00:18.630 So let's begin by the beginning and let's first create a defined for the energy bill and for the potential. 00:19.440 --> 00:25.010 So everything is still being driven and then define what an shmita. 00:28.470 --> 00:34.110 Which is number eight to all right in the center. 00:34.170 --> 00:35.920 So what do we need to set up? 00:36.530 --> 00:41.350 We need to set up the area for sure demoed because this is a digital thing. 00:42.140 --> 00:46.470 So and we need to set it as an output. 00:47.730 --> 00:53.940 OK, so that wait, no, know, not the potential amount of pain is an analog input means that we don't 00:53.940 --> 00:55.160 need to use B mode. 00:55.170 --> 00:57.570 It's already input B also. 00:57.570 --> 00:59.030 We don't need to yell here. 00:59.070 --> 01:03.030 So we are not going to and should I say also that's it for a setup function. 01:03.840 --> 01:05.190 We have our Thain's. 01:06.110 --> 01:12.050 Everything is set up now in the loop, we can start the main program, so what we are going to do, 01:12.320 --> 01:19.250 we are going to read the value from the pot on Shimano and provide this value to the entity that with 01:19.550 --> 01:24.980 this modification here where we need to scale down the value from the analog rate. 01:25.430 --> 01:29.360 So what I'm going to do first is to create a viable integer viable. 01:29.680 --> 01:31.040 OK, but on Schmitter. 01:33.370 --> 01:42.960 Value, which will store the value from the analog read function, so analog read and we provide the 01:42.960 --> 01:44.180 production with a peno. 01:45.590 --> 01:50.420 All right, so when we do that, this will return a value between zero and one thousand twenty three, 01:50.990 --> 01:53.510 which we store into that value. 01:54.640 --> 02:00.220 And I'm going to create that's another variable which will be added brightness. 02:01.470 --> 02:04.170 And this will be what I'm Schmitter. 02:05.550 --> 02:10.980 Value divided by four, I compute this. 02:11.000 --> 02:17.410 OK, so this will basically scale this down to zero and 255 to approximately. 02:17.510 --> 02:22.500 OK, we don't need to be super precise here that we divide the value by four. 02:22.530 --> 02:24.720 And then what we do is analog. 02:26.470 --> 02:30.530 Right before, right, we need to provide two parameters. 02:30.550 --> 02:32.380 First is the bin. 02:33.840 --> 02:35.130 And then the value. 02:35.160 --> 02:37.350 So the value is any brightness. 02:43.290 --> 02:48.450 And said, well, we don't really need to delay, we can just do that at full speed. 02:48.480 --> 02:49.860 OK, that's not really a problem. 02:50.400 --> 02:54.450 So to recap, first we define the beans as always. 02:54.450 --> 02:58.060 We set up the mode for the LDP as an output pin. 02:58.120 --> 03:01.230 OK, we read the value from the pot on Schmitter. 03:01.240 --> 03:06.570 We cannot agree to function these returns a value between zero and one thousand twenty three. 03:06.990 --> 03:14.260 We still add value and then we create another valuable to store the new value for the which is the punishment 03:14.280 --> 03:16.320 of a divided by four. 03:16.610 --> 03:20.580 So we take down the value and then we analog write. 03:20.580 --> 03:28.790 We can write on the digital bin for the entity and provide a policy in and duty cycle of the period. 03:28.870 --> 03:33.050 Um, is the any brightness between zero and two hundred twenty five. 03:33.720 --> 03:39.510 So again, make sure I agreed to read an analog input being an analog. 03:39.520 --> 03:39.960 Right. 03:39.990 --> 03:44.930 This is to write on a digital bin with the living functionality of it. 03:44.940 --> 03:46.950 Don't make the confusion between them. 03:47.760 --> 03:53.510 All right, so let's just compile a code to see if it's just working activity. 03:57.830 --> 04:03.380 It's done complaining, so we don't have any error, if you have an error here, then you fix the problem 04:03.380 --> 04:04.970 and you try to combine again. 04:05.270 --> 04:08.050 And no, that's the code. 04:09.800 --> 04:17.090 Right, the court is applauded and as you can see, so the energy is boiled on here because simply the 04:17.090 --> 04:21.820 put on trimethyl is at some point between the minimum and maximum and the minimum. 04:22.220 --> 04:25.340 So we have this energy here with this brightness. 04:25.340 --> 04:32.660 And no, I'm going to move the matter here back to the minimum and you can see the energy just fade 04:32.660 --> 04:33.020 out. 04:34.160 --> 04:35.150 I'm going to turn. 04:36.390 --> 04:42.480 Increase the value and you can see the aid now is becoming more and more bright and more intensity, 04:42.670 --> 04:52.800 and then I turn it back low intensity so I can just that the brightness I want directly from the bottom 04:52.890 --> 04:53.100 of it. 04:53.310 --> 04:55.650 And as you can see, it's currently walking. 05:01.130 --> 05:07.550 And you can see here also the results on tinkered with the simulation, so I have just the exact same 05:07.550 --> 05:11.810 code we used for the activity and studied the simulation. 05:11.840 --> 05:15.380 Now, here's the potential, a look at the energy here. 05:15.410 --> 05:17.210 So the conundrum is at the minimum. 05:17.250 --> 05:25.750 Now I'm going to turn it all the way up and you can see the energy, the in and the energy laid out. 05:27.020 --> 05:30.510 So it's working just as with the real secrets and. 05:30.510 --> 05:31.640 Well, congratulations. 05:31.640 --> 05:33.380 That is the end of the activity.
