WEBVTT 00:00.180 --> 00:06.900 In this activity, you are going to practice with the EPROM memory, but also with multitasking, a 00:06.900 --> 00:12.790 program with an entity, a potential monitor and reading data from the cellular communications. 00:12.790 --> 00:14.900 So quite a lot of things together. 00:15.420 --> 00:16.720 But what is your challenge here? 00:16.740 --> 00:19.290 Your challenge will be to make an. 00:21.190 --> 00:27.310 Fade in and fade out from the value you read from the potential. 00:29.600 --> 00:32.400 So that's actually something you already did before. 00:33.140 --> 00:39.560 So you are going to read the value from the bottom, which is an analog value from Narrabeen, and you're 00:39.560 --> 00:43.840 going to put this value with the analog right function in an eddy. 00:44.060 --> 00:52.790 So that's the on in then, OK, because you can only use between 10 and 11. 00:52.790 --> 00:54.080 So choose whatever you want. 00:54.350 --> 00:55.370 All right. 00:55.900 --> 00:57.860 So that's the first thing. 00:58.520 --> 01:03.840 But then you're going to add a cap for the intensity of the 80. 01:03.930 --> 01:08.270 OK, so you are going to set a maximum of max intensity. 01:09.600 --> 01:15.870 And this maximum, you are going to get it from the sale, so which means that you're going to open 01:15.870 --> 01:21.340 the sale mannitol and send some data and this will be the new max intensity. 01:21.630 --> 01:27.930 So, for example, you said the max intensity to one hundred fifty, which means that in the analog 01:27.960 --> 01:33.990 right function, you are only going to be able to send data from zero to one hundred fifty. 01:34.290 --> 01:37.160 And this is where we are going to use it from memory. 01:37.500 --> 01:40.680 You are going to save the max intensity. 01:41.660 --> 01:48.350 To people, so when you restart the program, you don't start with the default one instead of default 01:48.370 --> 01:51.670 one is two hundred fifty five, which is the maximum. 01:52.190 --> 01:58.760 But when you start the program, you are going to read from the apron, get the previous max intensity 01:59.090 --> 02:00.770 and set it as default. 02:01.340 --> 02:07.670 So whatever value you choose from, the sale will be kept for the next program execution. 02:08.120 --> 02:13.460 Again, one very important thing here is you are going to use one address on the one hand restaurant 02:13.540 --> 02:14.320 from memory. 02:14.840 --> 02:22.940 Pay attention to how and where you write on the April memory, OK, because if you write a program that 02:22.940 --> 02:27.860 is not behaving correctly and then you write too quickly into it from memory, the worst. 02:27.870 --> 02:32.690 So the worst that can happen is that you destroy an address of your memory. 02:33.230 --> 02:36.500 If you do that, you still have one thousand twenty three addresses. 02:36.980 --> 02:37.610 Well, that's fine. 02:37.740 --> 02:43.560 That is part of the learning experience, but that's also fine if you don't destroy any address. 02:43.910 --> 02:49.040 So if you have any doubt watched the beginning of the solution, first, what we're going to do is the 02:49.040 --> 02:49.610 solution. 02:49.790 --> 02:53.960 Just the first thing is to use the cellular read. 02:54.290 --> 02:59.530 And instead of writing to the from memory, I'm simply going to print what we have right. 02:59.780 --> 03:06.070 Just to make sure that we don't print too often, only when we have read something that is valid. 03:06.470 --> 03:12.420 And then once this is working, I'm going to remove the sale print and instead write to the AP from 03:12.440 --> 03:12.830 memory. 03:13.520 --> 03:13.910 All right. 03:13.920 --> 03:16.250 So you have enough information to get started. 03:16.460 --> 03:17.630 I will see you in the next. 03:17.680 --> 03:19.070 Listen for the solution.
