WEBVTT 00:00.050 --> 00:01.070 Congratulations. 00:01.070 --> 00:04.760 You have finished the final project of this course. 00:04.790 --> 00:10.160 This is yet another great achievement on your journey with Raspberry Pi and Arduino. 00:10.160 --> 00:15.980 And now, well, even if this project is finished and correctly working, there are many things you 00:15.980 --> 00:20.210 could work on to improve it or add new functionalities. 00:20.240 --> 00:26.230 The most interesting thing you could do is to adapt the project for your own needs. 00:26.240 --> 00:33.230 For example, if you want to implement an intercom system where you live and then if you are still craving 00:33.230 --> 00:38.620 some more practice, here are a few suggestions of things you could work on. 00:38.630 --> 00:42.650 So for the LCD screen you could make the text move. 00:42.680 --> 00:49.790 If you have more than 32 characters, okay, so you can display everything even a longer text. 00:49.820 --> 00:57.020 You could also add a telegram callback so you can send custom text from telegram to the LCD. 00:57.020 --> 00:59.420 So we've already done that actually before. 00:59.450 --> 01:03.000 In a previous activity, but you could add that to the project. 01:03.000 --> 01:08.970 So for example, if you recognize someone on the photo, you can say, for example, Hello John, how 01:08.970 --> 01:09.540 are you? 01:09.870 --> 01:17.040 Or just send a message like after the door, just go right and third door on the left then about the 01:17.040 --> 01:17.630 servo. 01:17.640 --> 01:24.900 So I've told it before, but you can attach it to a real door mechanism and define the opening and closing 01:24.900 --> 01:25.560 speed. 01:25.560 --> 01:28.920 So this would be the more mechanical part to the project. 01:28.950 --> 01:29.220 Okay. 01:29.220 --> 01:36.090 Where you will have to basically experiment, find out how you can attach to a door mechanism or just 01:36.090 --> 01:41.400 any mechanism that's going to allow a door to be opened and then, well, maybe define an opening and 01:41.400 --> 01:46.380 closing speed, because for some mechanism, if you try to go too fast, that's going to apply too much 01:46.380 --> 01:49.140 torque on the servo and it's not going to like it. 01:49.140 --> 01:50.790 So maybe you need to go slower. 01:50.790 --> 01:54.360 But this of course, there are millions possibilities. 01:54.360 --> 02:00.450 It really depends on the physical configuration you have for your door or the mechanism for the camera. 02:00.480 --> 02:02.730 You could take a video instead of a photo. 02:02.760 --> 02:06.180 Okay, so you send a few seconds video to Telegram. 02:06.570 --> 02:08.970 You could also and that's something different. 02:08.970 --> 02:15.600 You can also diffuse a video string with the Mjpeg streamer, so that's something you can check on the 02:15.600 --> 02:20.100 Internet and that's also something you could use for a surveillance system. 02:20.100 --> 02:26.490 So basically with this streamer, you can have an URL, you're going to check, and in this URL you're 02:26.490 --> 02:32.790 going to have a constant stream of video, which is maybe better than just one photo, but it's also 02:32.790 --> 02:35.310 more complex and I will leave you to it. 02:35.340 --> 02:37.650 You can decide to do this if you want to. 02:37.680 --> 02:42.750 You can also enable or disable the message sending from Telegram. 02:42.900 --> 02:49.410 So basically what I mean by that is that from Telegram you have the option, the deny and the start 02:49.410 --> 02:49.920 comments. 02:49.920 --> 02:55.320 You could also add, enable or disable so that basically you don't receive any notification from the 02:55.320 --> 02:56.130 Raspberry Pi. 02:56.130 --> 03:01.830 So when you send disable in the Raspberry Pi, whenever someone presses on the push button, well you're 03:01.830 --> 03:06.120 not going to do anything because you don't want to receive messages on telegram. 03:06.120 --> 03:13.920 And when you send enable, well you allow the application to send you some messages and some photos. 03:14.010 --> 03:18.510 Another improvement here could be that if you don't have any response after you press the button, for 03:18.510 --> 03:25.140 example, after 30s, you could come back to the default state because what's happening here is that 03:25.140 --> 03:30.240 once you have pressed on the push button, you're only going to come back to the default state after 03:30.240 --> 03:31.670 you have received a response. 03:31.670 --> 03:35.220 So open door or a denied access response. 03:35.220 --> 03:40.200 And so if no one is answering, well, the state is just going to be stuck in the. 03:40.200 --> 03:41.250 Please wait. 03:41.280 --> 03:41.520 Okay. 03:41.520 --> 03:46.740 So maybe you want to come back to the initial state with another message, for example, that no one 03:46.740 --> 03:53.790 could answer your request and then come back to the initial state after 30s one minute as you want. 03:53.790 --> 03:58.560 And one thing you could also do, and this has nothing to do with the functionalities, but more with 03:58.560 --> 04:02.100 the code is to optimize the code with multiple files. 04:02.100 --> 04:07.110 So we have just used one file for Arduino and one file for the Python program. 04:07.110 --> 04:07.350 Okay. 04:07.350 --> 04:13.620 What you could do is to separate the different functionalities and implement them on different files 04:13.620 --> 04:17.040 that you're going to call from your main file and use them here. 04:17.040 --> 04:22.590 And so you're going to have a better code organization and your code is also going to be more scalable 04:22.590 --> 04:23.550 in the future. 04:23.550 --> 04:25.950 And well, this list is not exhaustive. 04:25.980 --> 04:29.280 Those were just a few ideas and suggestions. 04:29.340 --> 04:36.210 I encourage you to come up with your own ideas and implement them so you can practice more and improve 04:36.210 --> 04:38.340 the project for your own needs. 04:38.340 --> 04:42.560 And well, once again, congratulations for finishing this project. 04:42.570 --> 04:44.130 This is the end of the project. 04:44.160 --> 04:47.160 Let's go to the conclusion section of the course.
