WEBVTT 00:00.240 --> 00:07.530 Let's no use the infrared remote control from our coup, but before that, we are going to need to do 00:07.530 --> 00:08.200 something. 00:08.220 --> 00:12.040 OK, we are going to need to install an Arduino library. 00:12.300 --> 00:17.360 So in this lesson, you're going to learn how to install a new ad in the library that is not in the 00:17.370 --> 00:23.550 school libraries that you already have in the and when you install the idea, for example. 00:23.880 --> 00:29.880 So you have seen that we have used libraries before and we have included libraries like EPROM or like 00:29.880 --> 00:31.590 the Liquid Crystal Library. 00:31.860 --> 00:36.870 And we just need to include and then put the name of the library and it worked. 00:37.530 --> 00:44.910 And here the library we are going to need is why are we so uppercase infrared and in lowercase remotes 00:45.180 --> 00:46.380 dot h. 00:46.410 --> 00:51.690 OK, so that's the library we are going to use and let's actually just verify. 00:52.170 --> 00:56.990 So let's name these remotes and we have an era. 00:57.000 --> 00:57.910 What is the era. 00:58.410 --> 01:04.830 You can see our remote no such file directory, which means that this was not found. 01:05.100 --> 01:11.830 And if it was not found, it's probably because the two options here maybe have written the name and 01:12.150 --> 01:13.370 not correct way. 01:13.680 --> 01:20.550 So, for example, here, if it's a bookcase and you put the lower kids to work, but here we are pretty 01:20.550 --> 01:23.190 sure that this is a correct syntax, but it's not working. 01:23.200 --> 01:23.450 Why? 01:23.460 --> 01:29.150 Because we need to actually manually install the library and how to do that? 01:29.280 --> 01:34.020 Well, we can go to tools and manage libraries. 01:34.300 --> 01:36.420 You can see also here the shortcut. 01:41.100 --> 01:48.160 OK, and you get to the library manager, so here you have all the libraries that you can use in your 01:48.210 --> 01:51.660 county, you can see that actually already quite a lot. 01:51.990 --> 01:56.050 And to browse the libraries where you can just use the search bar here. 01:56.280 --> 02:03.810 So let's, for example, it's type liquid back and just wait a little bit and you can see liquid crystal. 02:03.810 --> 02:07.710 That is the library that we have previously used for the LCD. 02:08.400 --> 02:10.240 And you can see it's already installed. 02:10.260 --> 02:12.930 So that was already done for us. 02:13.140 --> 02:15.140 But now the library we want to use. 02:15.330 --> 02:17.520 So I'm going to type in and. 02:19.190 --> 02:25.760 And weight limit and you can see the library we want to use is actually that remote. 02:26.450 --> 02:35.450 So you can see by sheriff here that three T o and so that's probably the shadows of the people in GitHub 02:35.450 --> 02:37.370 that developed that library. 02:37.670 --> 02:40.410 And you can see that library is not installed. 02:40.910 --> 02:48.470 So what we can do is we can click on install to install it and that's what we install the latest version. 02:48.680 --> 02:55.040 OK, well, we currently eat three point zero point three, so maybe that's going to be higher for you 02:55.400 --> 02:58.810 because the developers continuously update the library. 02:59.120 --> 03:04.430 But actually what I'm going to do is I'm not going to install the first three point zero point three. 03:04.430 --> 03:09.830 I'm going to go down and install the two point six point one. 03:09.830 --> 03:11.500 So select that one, OK? 03:12.080 --> 03:16.610 And I'm going to come back to this later and then we're going to use the library version three. 03:17.030 --> 03:19.280 OK, so let's install it so you can choose. 03:19.290 --> 03:24.390 You can see now it's installed so you can choose whatever version you want, OK? 03:24.720 --> 03:30.240 For one library, you have multiple versions which correspond to multiple iteration of the library. 03:30.680 --> 03:35.970 So now you have the library which is installed with two point six point one. 03:36.410 --> 03:39.250 So in the following, listen, I'm going to use this version. 03:39.290 --> 03:44.780 And in the lesson after that, we are going to switch to version three and I'm going to explain why 03:44.780 --> 03:46.880 we did that and what are the different. 03:47.360 --> 03:51.100 So now that it's installed, you can close the library manager. 03:51.110 --> 03:57.320 So any time you just go back to tool library management, we've managed libraries and now let's just 03:57.320 --> 03:58.490 verify again. 04:01.930 --> 04:03.670 And now it works, OK? 04:03.700 --> 04:10.000 The remote was found and I'm going to show you actually where is that library? 04:10.000 --> 04:12.750 Because the library will be installed on your computer. 04:13.000 --> 04:17.700 So if you go to your so I have this computer documents and outranged. 04:17.740 --> 04:20.480 This is where I have all my sketches of all my programs. 04:20.560 --> 04:22.410 You can see all the activity and stuff. 04:22.900 --> 04:28.630 And we have a folder that one should already be there called libraries. 04:29.290 --> 04:32.940 So you're going to libraries and at the beginning this will be empty. 04:32.950 --> 04:41.160 We've just read me the text with some information and you are for the guide of how to use the libraries. 04:41.680 --> 04:48.100 And now you can see we have a new folder named I Are Remote, and that's the library we have installed. 04:48.700 --> 04:54.170 So you go on your Ardino folder and then libraries and you get all the libraries you have. 04:54.190 --> 04:58.040 So if you want to uninstall a library, you can also directly. 04:58.040 --> 04:58.720 That's very easy. 04:58.720 --> 05:04.310 You just remove the folder here and the library is going, all right. 05:04.540 --> 05:11.050 You know how to install the next on a library in the original 80 and note that this doesn't apply to 05:11.050 --> 05:11.940 Tinker Kaloogian. 05:11.950 --> 05:17.920 Tinker, can you already have a set of libraries you can use with some nations that are already set? 05:18.190 --> 05:22.810 You can't install new libraries on Tinker Cartful, not only on the.
