WEBVTT 00:00.270 --> 00:07.050 In this activity, we are actually going to start from the code, from the previous activity, so I 00:07.050 --> 00:14.250 have here created a new file and I just took the entire code from the previous HDD, which already works. 00:14.460 --> 00:20.010 And the goal of this activity is to practice with functions, arrays and folders. 00:20.520 --> 00:23.230 So we are going to improve that program. 00:23.380 --> 00:28.550 OK, we're going to keep the exact same functionality, but improve that program. 00:29.160 --> 00:31.770 So what are you going to do here? 00:32.040 --> 00:39.500 Well, first, you can see we have three entities and we handle you can see here we do promote multimode 00:39.750 --> 00:40.130 digital. 00:40.140 --> 00:41.160 Right, right. 00:41.490 --> 00:41.910 Right. 00:42.450 --> 00:45.630 So this is quite a lot of repetition in the code. 00:46.050 --> 00:53.850 So what you do is you will create an array to contain the things for the entities. 00:54.180 --> 01:01.800 And then let's say here for all the modes you are going to instead of writing code three times, you 01:01.800 --> 01:07.760 are going to create a follow up, go through all the pins and set all the pins to. 01:09.090 --> 01:16.580 The same goes for the initialization return of all it is you are going to create here a or. 01:17.870 --> 01:25.340 And then as a second step, what you are going to do is put this into a function, so to set the mood 01:25.340 --> 01:34.940 for the things and then this into another function, to turn off all the attendees and then this cue 01:35.060 --> 01:37.250 this block of code. 01:39.120 --> 01:46.680 Where you toggle the state, you are also going to put it inside a function that DNA will have one, 01:47.130 --> 01:54.490 two and three functions, so the void setup and the void loop functions will be much more later. 01:55.290 --> 01:58.680 And just going to give you a few tips to get started. 01:59.130 --> 02:00.890 So let's actually create the array. 02:00.900 --> 02:03.870 So just continue here in the global scope. 02:04.320 --> 02:06.020 The first you need to give a type. 02:06.360 --> 02:08.910 And what is the type of this? 02:08.910 --> 02:16.990 Well, the type of this, the type of the pins here is actually not exactly inert, but instead bite. 02:17.550 --> 02:18.480 OK, what is Bayt? 02:18.870 --> 02:20.520 Is it the first time we use bite? 02:20.880 --> 02:27.990 You have heard previously that, for example, I said integer is stored on two bytes and along is stored 02:27.990 --> 02:37.140 on four bytes case or that is simply that I type which contains wrong numbers from zero to two hundred 02:37.380 --> 02:38.420 and fifty five. 02:39.030 --> 02:42.330 If you remember from what we did with the analog right. 02:42.330 --> 02:43.980 Function with repeatably when. 02:43.980 --> 02:48.000 Well that's exactly disarranged a bit a brain function. 02:48.000 --> 02:54.840 Actually the parameter that you sent to it in the right was about nothing really complicated about is 02:54.850 --> 02:59.130 simply an integer but smaller just on one byte. 02:59.140 --> 03:01.060 So zero to two hundred fifty five. 03:01.590 --> 03:07.890 So the name for the array will be in the right it. 03:08.040 --> 03:10.830 So you can choose this name and then you need to give. 03:12.010 --> 03:18.910 The site is the site would be three, but actually instead of help getting the site, we can maybe create. 03:20.350 --> 03:25.990 Another defining entity in the right. 03:27.250 --> 03:28.050 It's a. 03:29.450 --> 03:30.740 This is quite explicit. 03:32.990 --> 03:35.000 It's been a recital three. 03:35.020 --> 03:37.090 And then we simply do this. 03:39.000 --> 03:39.840 Right here. 03:41.130 --> 03:46.740 All right, so this is better because if we want, for example, to add a new entity, we simply add 03:46.740 --> 03:53.640 a new entity, we simply increase by one year and let's initialize the area that we are simply going 03:53.880 --> 03:55.950 to give into the three brackets. 03:57.070 --> 03:58.270 And the one being. 03:59.280 --> 04:01.020 And then energy to pin. 04:02.070 --> 04:04.880 And then at three know. 04:07.750 --> 04:18.070 And use a semicolon and as you can see here, we have a quite long line, OK, and it's quite recommended 04:18.070 --> 04:21.050 when you program to keep lines quite short. 04:21.230 --> 04:27.970 OK, so here in my program, I have found 18 and to make it more readable, what I can do is simply 04:27.970 --> 04:35.530 after the equals sign here, I'm going to press enter and this price tag puts a few times doesn't really 04:35.530 --> 04:35.970 matter. 04:36.310 --> 04:43.820 And just put this on a new line if you have this, but equal sign and then something on the new line. 04:43.840 --> 04:45.990 Well, this is the following of the statements. 04:45.990 --> 04:49.660 So is just like it was one line, but it's much more reliable. 04:49.680 --> 04:53.840 OK, have the time, array the size and then you see the values here. 04:54.460 --> 04:54.810 All right. 04:54.820 --> 05:02.260 So you have the array and then you can use this right to actually that's the pin mode that the digital 05:02.260 --> 05:05.920 right initialize the any and the function. 05:05.960 --> 05:09.850 So here just going to give you the name of the function. 05:09.880 --> 05:15.430 So this would be a void function mode and you can name it, for example, said LTT. 05:16.610 --> 05:17.720 Incommode. 05:19.560 --> 05:22.070 And here you can, for example, it. 05:23.450 --> 05:26.480 Then of all these. 05:29.090 --> 05:35.180 OK, so you trade to function here on the top of the program after the initialization of the valuables 05:35.180 --> 05:41.420 and constant and insider function, use a follow up to go through all of the ends of the. 05:43.200 --> 05:49.410 And then for this, but you can use a function, let's say. 05:51.210 --> 05:54.780 Which name is Pogo, and it is. 05:57.150 --> 06:02.490 All right, so now you have enough information to work on and I will see you in the next listen for 06:02.490 --> 06:03.120 the solution.
