WEBVTT 00:00.210 --> 00:06.240 This is the solution of the previous activity where you need to complete this project to create a full 00:06.240 --> 00:07.840 multitask project. 00:07.930 --> 00:15.360 OK, by setting the analogy to write from the potential meter and by borrowing on the three when the 00:15.360 --> 00:16.770 button is pressed. 00:17.220 --> 00:20.070 OK, and what I'm going to do, because here it's activity nine. 00:20.070 --> 00:21.840 So I'm not going to write code on this. 00:21.840 --> 00:29.820 I'm going to write everything, copy everything, and then create a new project and then everything. 00:29.830 --> 00:39.450 So we start on the new project that I am going to compile and save as activity in. 00:41.370 --> 00:49.170 All right, so our first action, which is to change the delay for the blank, for any one, is already 00:49.500 --> 00:49.970 done. 00:50.520 --> 00:58.010 So not what we can do is to do this action, which is to set the energy brightness from the potential. 00:58.800 --> 01:10.650 So the we need to hear the fine energy to in is Ongpin number 11 so we can use the PWI in functionality 01:10.860 --> 01:11.310 on that. 01:11.310 --> 01:16.950 People also here and I'm simply going to rename it as the one thing. 01:17.680 --> 01:21.990 OK, I'm just going to add one little delay. 01:23.120 --> 01:23.810 Let's see. 01:25.110 --> 01:28.110 Anyone one, any one state. 01:30.650 --> 01:32.180 Linda, that is one. 01:33.820 --> 01:35.310 It just to make more sense. 01:37.830 --> 01:46.470 Because we have multiple entities in here and it is one thing, and you are at any one state and one 01:46.470 --> 01:50.100 state, you want also one here. 01:52.810 --> 01:53.830 In and. 01:55.090 --> 01:59.810 OK, let's just come by to see if I have any error, no. 02:01.210 --> 02:06.310 OK, so if you just have one entity, then it's OK not to put a number on it, but here because we have 02:06.310 --> 02:11.800 multiple ones, I just want to make sure that it will not be confusing later. 02:12.670 --> 02:15.430 So we find Eddie to be 11. 02:15.820 --> 02:18.950 This are having to initialize it here. 02:18.970 --> 02:23.740 So queen mode up in output. 02:26.120 --> 02:32.420 And then in the loop, we are going to sit brightness from the potential of this, so we need potentially 02:32.420 --> 02:34.430 to define. 02:37.140 --> 02:43.830 But extreme weather in which she's a tool, OK, we don't need to actually do spin mode because this 02:43.830 --> 02:45.330 is an analog input being. 02:46.660 --> 02:53.070 Right, and then in the loop, so what I'm going to do, I'm simply going to do the action here, OK, 02:53.440 --> 02:55.900 so we have action one. 02:58.760 --> 02:59.510 According to. 03:00.950 --> 03:09.320 And then action three, action three is simply to get the put on shareholder value put on Shimura. 03:10.870 --> 03:14.850 Value is equal to analog radio. 03:14.920 --> 03:17.620 OK, with the lunchmeat a cleaner. 03:20.960 --> 03:22.490 All right, now we can do. 03:24.530 --> 03:26.510 In intensity. 03:27.940 --> 03:29.400 Which will be put on Sumate. 03:31.270 --> 03:33.820 Value divided by four. 03:33.890 --> 03:40.960 OK, if you remember, the value we get from an is between zero and one thousand twenty three and the 03:40.960 --> 03:49.340 value we can give with the analog right function is between zero and two hundred fifty five. 03:49.360 --> 03:51.970 So we need to divide the value by four. 03:53.120 --> 03:58.430 So, Andrew, great to write on PIN number 11 with the W.M. function. 03:59.690 --> 04:03.770 And to deal with intensity. 04:05.740 --> 04:11.590 And that is the action three and here, this will not pose any problem because this is quite fast, 04:11.630 --> 04:16.500 OK, we use an override function, so this will not block the code for too long. 04:16.840 --> 04:19.770 Then we just do an operation and we are going to go, right, OK. 04:19.780 --> 04:22.570 We don't use any delay, though, because we don't use the delay. 04:23.020 --> 04:24.880 We don't need to use that structure. 04:25.240 --> 04:32.650 It does structure is only when you use delay and basically only when you want to wait a certain time 04:32.800 --> 04:35.080 before you do a different action. 04:35.320 --> 04:42.820 So here, if we wanted, for example, to update the energy intensity, but not every time we enter 04:42.820 --> 04:49.180 the loop, but instead, for example, every three hundred milliseconds, what we could do is use this 04:49.180 --> 04:49.800 structure. 04:50.200 --> 04:52.540 But because we want to do it as fast as possible. 04:52.570 --> 04:53.870 Well, that's not a problem. 04:54.580 --> 04:56.590 And now the action for. 04:59.490 --> 05:12.180 Which is simply too poor on the third when we raise the budget, so we need to find a way in which it's 05:12.180 --> 05:15.660 been a 10, I'm going to initialize it here. 05:17.270 --> 05:17.780 Mode. 05:18.650 --> 05:18.950 A. 05:20.620 --> 05:21.810 Three in. 05:25.620 --> 05:26.910 And we also need. 05:28.780 --> 05:29.500 Who define. 05:31.260 --> 05:31.920 Button. 05:33.110 --> 05:41.870 In which he has been number two, the digital pin number two, and also teen mode button pin. 05:43.580 --> 05:44.750 In what? 05:48.040 --> 05:55.390 We have initially been not in the loop, we can do the action, so now what we can do is check if. 05:56.320 --> 05:59.680 Digital read Butterbean. 06:01.810 --> 06:06.010 Is equal to I wish to equal saying. 06:07.810 --> 06:12.220 Then we enter this book of code and we put on so digital. 06:14.160 --> 06:14.720 Right. 06:15.900 --> 06:16.520 Ali. 06:17.680 --> 06:19.090 Three senior. 06:20.460 --> 06:25.950 We've high we report on the 83 and of course, don't forget the elsea. 06:28.440 --> 06:38.280 If the button is not pressed, we need to pull off digital, right, and the thing we need to pull it 06:38.330 --> 06:38.550 off. 06:40.050 --> 06:40.460 All right. 06:40.470 --> 06:41.070 And that's it. 06:41.100 --> 06:48.750 So as you can see, this also doesn't need a delay, OK, because we want to update this as fast as 06:48.750 --> 06:52.300 possible, as fast as we did the data, just as we did here. 06:52.860 --> 07:00.030 So if you wanted to update only every one hundred milliseconds and you would have used a structure like 07:00.030 --> 07:00.390 this. 07:00.840 --> 07:02.720 OK, but we disagree with you. 07:02.730 --> 07:05.800 What I want to show you is that create a multitask program. 07:06.180 --> 07:13.220 You simply need to do all the operations, OK, all the actions you want to function one by one. 07:13.620 --> 07:17.860 Just make sure that no action is blocking the execution. 07:17.880 --> 07:24.390 OK, because here we have four different actions no one is blocking will delay, which means that they 07:24.390 --> 07:27.480 are going to be executed very, very fast. 07:27.850 --> 07:34.080 So because they are executing very, very fast, then it's almost like they are executed at the same 07:34.080 --> 07:34.470 time. 07:34.680 --> 07:37.470 And this is where you have the multitask program. 07:38.480 --> 07:42.590 All right, and now let's applaud that programme to our Adreno. 07:43.940 --> 07:44.330 All right. 07:44.330 --> 07:50.180 And you can see here, so we have our first energy, which blinks every five hundred milliseconds, 07:50.420 --> 07:51.850 let's say, on monitor. 07:52.210 --> 07:53.690 And I can just change it. 07:53.690 --> 07:54.670 Let's say 200. 07:54.680 --> 07:56.060 It blinks much faster. 07:56.450 --> 07:57.860 Let's say three dozen. 07:57.860 --> 08:00.530 It blinks every three seconds. 08:01.960 --> 08:08.510 OK, and we have our second lady here, you can see is already power on it, but because this is from 08:08.510 --> 08:14.320 the bottom shmita, I can increase and decrease the value, as you can see from the bottom me, that 08:15.580 --> 08:20.050 this is happening at the same time as the first lady blink. 08:20.410 --> 08:28.810 And what I can do is from the bottom, I can also power on the third and this and I can do everything 08:28.810 --> 08:29.450 at the same thing. 08:29.520 --> 08:30.310 OK, yeah. 08:30.310 --> 08:37.000 And moving the production meter, I put on the push button, I press the button at the same time you 08:37.000 --> 08:39.490 can see the first lady is still blinking. 08:40.120 --> 08:43.170 So everything is happening at the same time. 08:45.520 --> 08:47.690 All right, so that's the end of this activity. 08:48.190 --> 08:53.710 Now, you should have a better understanding on how to use the time functionalities so you can avoid 08:53.710 --> 09:00.040 using delay in the volume function and you can create as many actions as you want. 09:00.080 --> 09:06.130 OK, you just need to put all the actions in the order you want and then they are going to be executed 09:06.130 --> 09:10.790 so fast, which means that you have created a multitask program. 09:11.170 --> 09:12.090 Congratulations. 09:12.100 --> 09:14.440 That's the great progress you have just made.
