WEBVTT 00:00.270 --> 00:00.600 All right. 00:00.600 --> 00:03.810 And now let's use the remote library. 00:03.810 --> 00:06.120 But this time, the version three. 00:06.300 --> 00:11.460 So why did I start with version 2.6.1, and then I'm going to use version three. 00:11.460 --> 00:13.590 Well, actually, for two reasons. 00:13.710 --> 00:19.170 First, most of the examples in code you will find on the Internet are using the version two. 00:19.260 --> 00:24.840 And so if you find a different code that is on version two, you know how it works. 00:24.840 --> 00:29.190 And the second version also is because what you are going to see that on Tinker code. 00:29.280 --> 00:32.240 Well, Tinker Cat only uses the version two. 00:32.250 --> 00:36.050 And the thing is, we can't update the libraries on Tinker. 00:36.450 --> 00:40.050 So on the original idea, we are going to do that. 00:40.080 --> 00:43.740 We can change the library, we can change the version, we can change everything. 00:43.740 --> 00:49.800 We have the complete control on Tinker that you don't have the control of which library in which version 00:49.800 --> 00:51.360 of the library is installed. 00:51.360 --> 00:53.980 So Tinker, you can only use that code. 00:54.000 --> 01:00.270 So now what I'm going to do, I'm going to so copy all the code and create a new file here. 01:01.770 --> 01:08.580 Let's paste the code and this is where we are going to use the version three of the library and to be 01:08.580 --> 01:13.230 able to use the version three, I'm going to go to tools, manage libraries. 01:16.040 --> 01:21.110 Or you can see here it updates the list and then I'm going to go to air remote. 01:23.520 --> 01:24.810 And find the library. 01:24.810 --> 01:27.210 So we have version 2.6.1. 01:27.210 --> 01:28.620 So we are going to. 01:28.650 --> 01:31.980 So what you can do is click on update or choose the version here. 01:31.980 --> 01:34.250 So I'm going to choose the latest version. 01:34.260 --> 01:36.810 If you click on update, that's going to do the same. 01:36.810 --> 01:41.040 So again, for me, the latest version here is 3.0.3. 01:41.040 --> 01:41.460 For you. 01:41.460 --> 01:48.600 It might be higher, so you might want to just take the latest version and if it doesn't work, come 01:48.600 --> 01:53.160 back to this version or even the 2.6.1, but this should work for you. 01:53.400 --> 01:55.110 Okay, so let's install this. 01:55.110 --> 02:02.130 And you can see now we have installed with version 3.0.3, which is a new version. 02:02.250 --> 02:07.710 And this version actually has breaking changes with the version two, which means that the code here 02:07.710 --> 02:10.470 would not just work like this, you will need to modify it. 02:11.160 --> 02:17.100 And now we're using the version three well, because it's simply usually better to update your libraries 02:17.100 --> 02:22.980 and to use the latest available version, which should be more stable with better functionalities, 02:22.980 --> 02:24.990 better performance, etc.. 02:25.080 --> 02:28.890 So now what happens if I try to compile this code? 02:28.890 --> 02:33.540 So let's name it remote and V three. 02:36.600 --> 02:36.840 Okay. 02:36.840 --> 02:41.220 So as you can see here, we don't have any problem for compilation. 02:41.520 --> 02:44.580 So let's try to just upload the code and see what it does. 02:46.270 --> 02:49.620 Okay, so now I'm going to open the side monitor, so make sure you upload the new code. 02:49.630 --> 02:49.930 Okay? 02:50.170 --> 02:52.710 Make sure you don't just verify, but that you upload. 02:52.720 --> 02:55.060 Let's open a site and monitor and. 02:55.060 --> 02:55.960 Oh, whoa, whoa. 02:55.960 --> 02:57.070 What is that? 02:57.550 --> 02:59.580 We have a lot of errors. 02:59.590 --> 03:04.480 The function decode result is deprecated and may not work as expected. 03:04.480 --> 03:10.600 Just use decode without any parameter and well, it's kind of so it's not working. 03:10.600 --> 03:13.330 If I press some button, well, that's not going to work. 03:13.330 --> 03:19.060 We have a lot of error messages and that is because we are using the code for the version two, but 03:19.060 --> 03:20.560 using the version three. 03:20.710 --> 03:26.140 So for some reason it's still compiles, but then you have a lot of errors in the style monitor. 03:26.170 --> 03:30.010 So for the version three, we need to change completely the code. 03:30.020 --> 03:32.470 I'm going to remove all of that. 03:33.960 --> 03:35.850 And this also. 03:35.970 --> 03:37.040 So I keep this. 03:37.070 --> 03:40.950 I begin and I keep, of course, the defined for the pin. 03:41.070 --> 03:46.000 The name of the library is the same, but now things are different. 03:46.020 --> 03:50.790 So for the version three, you don't have anything to do in the global scope you are just going to do 03:50.820 --> 04:01.740 Here I are receiver, so I uppercase and then are lowercase and then receiver with uppercase dot begin 04:02.160 --> 04:04.710 and using the pin here. 04:05.940 --> 04:12.660 Air receivers like this that begin with the pin and this will initialize the library and the sensor. 04:12.780 --> 04:15.510 And then in the void loop we are going to do if. 04:16.610 --> 04:17.440 I also. 04:17.450 --> 04:18.350 Same here. 04:19.810 --> 04:25.830 If air receiver does decode, but this time we don't have anything in decode. 04:27.670 --> 04:35.440 Then when we can do is air receiver dot resume just like we did before. 04:35.440 --> 04:38.560 But now we use our receiver just like this. 04:39.250 --> 04:41.410 This is included in the library directly. 04:41.410 --> 04:48.670 So if we use the include when we write this, Arduino is going to find out what is that and then let's 04:48.670 --> 05:01.420 do some sale, let's print in and to get the results you will do I r receiver dot decoded i r data. 05:01.870 --> 05:03.760 So here I r is a case. 05:03.760 --> 05:09.010 Make sure you use the correct case because the case is very important here. 05:09.010 --> 05:11.440 It's case sensitive dot. 05:11.440 --> 05:14.950 So we have two ways of getting the data now decoded. 05:16.700 --> 05:21.170 Wrong data with, let's say, X. 05:21.410 --> 05:26.570 So we are going to print the decoded raw data with hexadecimal just like before. 05:27.050 --> 05:31.990 And we can also do sale dot print with i. 05:32.000 --> 05:32.540 R. 05:33.630 --> 05:35.970 Receiver Dot decoded. 05:37.700 --> 05:47.780 I r data dot com and this will actually give us a small number that is much easier to understand and 05:47.780 --> 05:48.890 much easier to control. 05:49.130 --> 05:55.790 So let's bring the two and I'm just going to add the print and then we've three dashes. 05:56.780 --> 05:57.130 Okay? 05:57.440 --> 06:03.380 So every time we read something, we can have three dashes to separate the results we get. 06:03.440 --> 06:07.280 And now let's run that code and let's upload it directly. 06:08.890 --> 06:10.610 And let's open the second monitor. 06:10.630 --> 06:12.410 And now we should not have any error. 06:12.430 --> 06:19.030 So I'm going to press any button and you can see when I press the button, I have an Exodus email result, 06:19.030 --> 06:23.140 which is also different from the one we had with version two. 06:23.620 --> 06:26.020 And we have second is a command. 06:26.320 --> 06:31.330 So if I press zero, I get this hexadecimal and the command 22. 06:31.360 --> 06:39.340 If I press one here, I get 12, I press two, I get 24, I press the let's say the on off button, 06:39.340 --> 06:45.310 I get 69, I press the play button, I get 64. 06:45.700 --> 06:47.620 So you get the hexadecimal value. 06:47.650 --> 06:53.530 If you have zero, it means that you have pressed the same button twice and then you also get a value 06:53.530 --> 06:58.210 that is actually easier to read and that is the value we are going to use. 06:58.210 --> 07:03.100 So from now on we are going to use the command that we get from the library. 07:03.250 --> 07:07.150 So as you can see, the version three of the library is an improved version. 07:07.150 --> 07:12.520 It's going to work better and we have a better data to handle. 07:13.030 --> 07:13.360 All right. 07:13.360 --> 07:15.880 And again, the code here, you don't need to really understand. 07:15.880 --> 07:21.580 Just know that you have to write this and then that you have to write this in order to get the information 07:21.580 --> 07:22.960 using the library. 07:24.380 --> 07:28.430 And now let's try to see what will happen if I try to put this code on. 07:28.940 --> 07:30.380 So I'm going to copy the code here. 07:30.410 --> 07:33.830 The code we have just used and put it on, think again. 07:34.190 --> 07:36.570 So now we are trying to use the version three. 07:36.590 --> 07:38.630 Let's start the simulation. 07:39.960 --> 07:41.580 And you can see we have some arrows. 07:41.580 --> 07:44.630 So what is the arrow in function void setup? 07:44.640 --> 07:48.810 I receiver was not declared in the scope so I r receiver. 07:48.810 --> 07:51.180 So here the line is not necessarily the correct one. 07:51.180 --> 07:55.890 This is that 1ir receiver is not known in the library. 07:56.010 --> 07:56.910 And why is that? 07:56.910 --> 08:00.570 Is because Tinker uses the version two of the library. 08:00.570 --> 08:05.750 So the I r receiver that is in version three is not known in version two. 08:05.760 --> 08:12.180 So if you use Tinker just here, this is the code for version two that's going to work. 08:12.180 --> 08:14.610 So if you use Tinker Cat, just use version two. 08:14.610 --> 08:19.500 And if you use your Arduino ID, well, I recommend you use version three. 08:19.500 --> 08:25.080 And for the following of this section, I'm going to keep using the version three of the library for 08:25.080 --> 08:29.700 the Arduino ID, but if you are following the course with Tinker Cat, well that's not really a problem 08:29.700 --> 08:33.810 because the code here, I'm not going to add anything else in that code. 08:34.050 --> 08:38.340 We are going to add code outside of the remote functionality. 08:38.340 --> 08:42.210 So this is all the code you need to get the sensor to work. 08:42.210 --> 08:48.540 So if you are using version two and I'm using version three, just modify the code for receiving the 08:48.540 --> 08:52.680 data with the remote controller and then everything else will be the same.
