WEBVTT 00:00.350 --> 00:03.800 You can now take photos using the Raspberry Pi camera. 00:03.950 --> 00:06.250 Let's now switch to the telegram bot. 00:06.260 --> 00:07.610 So why telegram? 00:07.790 --> 00:15.620 Well, telegram is a quite good and open messaging app with the possibility of creating useful bots 00:15.710 --> 00:22.850 about basically is a program that will interact with the chat on the telegram application and the bot 00:22.850 --> 00:29.540 will be running where we'll be running in the Raspberry Pi as a Python program, for example, you can 00:29.540 --> 00:36.140 send a message to a chat from the Raspberry Pi and you can also respond to some comments that you type 00:36.140 --> 00:37.400 directly on the chat. 00:37.430 --> 00:41.060 We are going to see both cases in the following lessons. 00:41.060 --> 00:47.600 But first we need to do a few configuration steps to create this bot on the Telegram app. 00:47.780 --> 00:52.520 The very first step is to create a telegram account from your phone. 00:52.610 --> 00:56.170 Telegram is free, so no problem with that. 00:56.180 --> 01:06.690 So you go to the Telegram website here with telegram.org and you download one of the application. 01:06.730 --> 01:07.220 Okay. 01:07.230 --> 01:13.590 So if you have like an Android phone, a iPhone or a Windows phone, for example. 01:13.590 --> 01:17.520 So you download the application and you just follow the setup. 01:17.550 --> 01:18.090 Okay. 01:18.270 --> 01:23.130 So with telegram you need to link your account to your phone number. 01:23.160 --> 01:23.400 Okay. 01:23.400 --> 01:26.760 That's why you need to start the account from your phone. 01:26.790 --> 01:30.990 Then you are free to use any of the phone, tablet or desktop application. 01:30.990 --> 01:33.000 So I'm not going to show you the setup. 01:33.000 --> 01:38.940 You just basically well, you just download an application and you just click on next until you get 01:38.940 --> 01:44.460 to the chat and then, well, you can use the application from anywhere. 01:44.460 --> 01:49.920 If you want to use your application from your phone, you can do that if you want to use the application. 01:49.920 --> 01:55.530 Also, you can download it for Windows, you can download it for Mac OS, you can download it for Linux. 01:55.530 --> 02:00.090 And that's what actually I'm going to do here is I'm going to use the application. 02:00.090 --> 02:07.170 So I have the application on my phone as well, but I'm going to use the application, the desktop application 02:07.170 --> 02:13.920 also from the Raspberry Pi desktop, just so it is simpler for me to record the video basically so I 02:13.920 --> 02:19.020 can have the Python program, the Arduino program, and I can also have the telegram application. 02:19.020 --> 02:19.500 Okay. 02:19.500 --> 02:22.320 But you don't need to use the telegram application here. 02:22.320 --> 02:24.780 You just use it anywhere you want. 02:24.780 --> 02:30.270 And so if you want to use the Telegram app from a Windows or Mac OS, you just download it from the 02:30.270 --> 02:38.700 website and if you want to use it from Linux, well you can just do sudo apt install. 02:39.710 --> 02:43.970 Telegram desktop with Autocompletion. 02:44.330 --> 02:44.780 Okay. 02:44.780 --> 02:53.330 And well, for me it's already installed, but well, on any Linux you just do this and then you will 02:53.330 --> 03:02.000 see that if you go to the menu and internet, you have the web browser and you have Telegram desktop. 03:04.850 --> 03:05.270 Okay. 03:05.270 --> 03:06.860 And now you have the Telegram app. 03:06.860 --> 03:11.930 So this will look exactly the same on mobile or on the desktop application. 03:11.930 --> 03:12.740 So that's great. 03:12.740 --> 03:15.920 Basically, you have a list of chats, you can have your contact, everything. 03:15.920 --> 03:19.370 So I'm not going to explain to you how a messaging app works. 03:19.370 --> 03:23.270 And now, well, your account is correctly configured. 03:23.300 --> 03:25.430 We can create a bot.
