WEBVTT 00:00.080 --> 00:03.410 It's now time to start the final project of this course. 00:03.410 --> 00:08.690 You have now completed all the learning steps and have a great knowledge foundation that you can use 00:08.690 --> 00:13.130 for any new project, including the one you are about to start right now. 00:13.160 --> 00:18.260 The project will be great for you to practice on everything you have seen in this course, and it will 00:18.260 --> 00:21.500 be your first real big project with a Raspberry Pi. 00:21.530 --> 00:23.660 So what is this project about? 00:23.660 --> 00:27.230 Here is the final result you will get at the end. 00:27.770 --> 00:31.010 So I am on the Raspberry Pi and I'm going to start the project. 00:31.010 --> 00:35.240 Actually we will have two different Python files for this project. 00:35.240 --> 00:38.390 So I will go in my documents and Python programs. 00:38.390 --> 00:40.700 I'm just going to put the programs here. 00:40.700 --> 00:46.850 And the first one I'm going to start with Python three is project step four. 00:46.850 --> 00:48.320 So that's the first program. 00:48.320 --> 00:53.120 I named it step four because for step one, two, three and four of the solution, I'm going to work 00:53.120 --> 00:54.560 on that program. 00:54.560 --> 00:59.840 So let's start this Python program and let's see what we get first. 00:59.840 --> 01:02.030 So you see we have email setup okay. 01:02.030 --> 01:03.800 So we're going to set up email. 01:03.800 --> 01:06.370 So those are logs that I print in the program. 01:06.580 --> 01:09.640 We're going to set up a mail client to send an email. 01:09.640 --> 01:11.530 We're going to also set up the camera. 01:11.830 --> 01:13.990 We are going to create a log file. 01:14.230 --> 01:20.290 So whenever we take a photo we're going to put the path to the photo inside a log file. 01:20.290 --> 01:22.450 So first we remove it when we start the program. 01:22.450 --> 01:25.510 And then every time we take a photo we add the photo in the log file. 01:25.510 --> 01:29.890 Then we set some gpios with an LED and a Pir sensor. 01:29.890 --> 01:31.870 And finally everything has been set up. 01:31.870 --> 01:33.670 Now what we want to achieve. 01:33.670 --> 01:36.460 So I'm going to show you with the circuit. 01:36.700 --> 01:40.510 So when I make a movement in front of the Pir sensor here. 01:40.510 --> 01:43.210 So I'm going to make a movement for five seconds. 01:43.210 --> 01:49.900 You see whenever the Pir sensor has the motion detected, I also turn on the LED. 01:50.140 --> 01:56.050 Okay, so now I'm making movement, the LED is on and I'm going to stop making movement and stay. 01:56.080 --> 02:03.940 So stay in front of the camera and you see that it's going to take a photo and send it by email okay. 02:04.480 --> 02:10.620 So the rule here is that if you make a movement in front of the Pir sensor so for more than five seconds 02:10.620 --> 02:11.730 and then you stop. 02:11.730 --> 02:15.120 Then the camera is going to take a photo and send it by email. 02:15.120 --> 02:17.970 It's also going to add the path to a log file. 02:18.360 --> 02:21.180 And I am on my email address here. 02:21.180 --> 02:24.870 So you see that I receive a new image. 02:25.170 --> 02:28.650 So those were the the different tests I made. 02:28.650 --> 02:30.180 And those are the two last ones. 02:30.180 --> 02:35.280 So you see we receive a new email from the email address that we have created. 02:35.280 --> 02:39.960 You see check out the new photo and we see the photo that we have taken. 02:39.990 --> 02:40.470 Okay. 02:41.310 --> 02:43.410 So this is the first program. 02:43.440 --> 02:45.120 You monitor the Pir sensor. 02:45.120 --> 02:50.160 So you can use the callback function for example to know when the motion is detected and when the motion 02:50.160 --> 02:56.700 is not detected anymore, and then check that at least five seconds have passed to take a photo and 02:56.700 --> 02:58.170 you send the photo by email. 02:58.200 --> 03:00.300 You also write it inside the log file. 03:00.300 --> 03:04.080 And that's basically, well, that's the main functionality of this project. 03:04.080 --> 03:08.190 Step four of the first program I'm going to stop this one. 03:08.220 --> 03:09.810 Actually you can still run it. 03:09.810 --> 03:10.950 It's not a problem. 03:10.950 --> 03:15.800 And I'm also going to go to my programs again here and run. 03:15.800 --> 03:20.960 So Python three Project Step. 03:21.110 --> 03:22.940 And that's going to be step six okay. 03:22.940 --> 03:27.980 Because in step five and step six we're going to work on the second Python program. 03:27.980 --> 03:35.810 And this one is going to start a flask web server okay I'm going to click here to open this. 03:38.120 --> 03:38.540 Okay. 03:38.540 --> 03:40.010 So that's the home page. 03:40.010 --> 03:42.320 It just says hello. 03:42.350 --> 03:47.720 But then we have slash check photos. 03:52.280 --> 03:54.860 All right so we have a URL check photos. 03:54.890 --> 04:00.590 That's going to say how many new photos were taken since we last checked okay. 04:00.620 --> 04:03.590 Since we last actually went to this page. 04:03.620 --> 04:07.310 It's going to also give us the path to the last photo. 04:07.310 --> 04:08.240 And then. 04:08.270 --> 04:12.110 Well, that's the that's the last photo that was taken by my camera. 04:12.140 --> 04:18.740 Now if I refresh you see we have zero new photo because that's since the last time that I refreshed 04:18.740 --> 04:19.700 this page. 04:19.730 --> 04:21.470 But we still have the last photo here. 04:21.500 --> 04:21.920 All right. 04:21.920 --> 04:27.410 So one program is going to take photos after a movement has been detected for at least five seconds. 04:27.410 --> 04:33.320 And then the other program is going to, well, print the photos and give you some information here 04:33.350 --> 04:34.880 on a web server. 04:34.880 --> 04:37.010 And that's going to be it for this project. 04:37.370 --> 04:41.180 To complete this project, you will need to use each part of this course. 04:41.210 --> 04:46.340 If you are stuck with one part, don't hesitate to come back to the corresponding lessons and watch 04:46.340 --> 04:47.150 them again. 04:47.150 --> 04:50.330 For some parts, you will also need to do your own research. 04:50.360 --> 04:55.640 One thing I encourage you to do is to use Google when you are stuck, or if you want to use a new feature 04:55.640 --> 04:57.410 that we didn't cover before. 04:57.440 --> 05:02.420 If you don't have the habit of searching stuff on Google, it's something you should definitely start 05:02.420 --> 05:03.350 to do right now. 05:03.350 --> 05:08.690 It will help you a lot when programming or using software, and it's something developers do all day 05:08.690 --> 05:09.260 long. 05:09.290 --> 05:10.160 Okay, because here. 05:10.160 --> 05:14.210 Not that I will give you some tips and instructions to get started with the project. 05:14.240 --> 05:21.130 You can also download the PDF with this lesson, but I'm not necessarily going to detail Every instruction 05:21.130 --> 05:22.150 before you get started. 05:22.180 --> 05:26.230 Okay, so it's also up to you to find a way to solve the challenge. 05:26.230 --> 05:31.660 And when working on the project, it's important that you take actually some time to really work by 05:31.660 --> 05:34.030 yourself before you watch the solution. 05:34.030 --> 05:39.250 This is the best way you can make progress and fully understand what you learned before, and I will 05:39.250 --> 05:41.230 provide you with a step by step solution. 05:41.230 --> 05:46.030 Just be aware that the solution I provide is just one solution. 05:46.030 --> 05:48.640 It's not necessarily the solution. 05:48.640 --> 05:54.280 If you can get the same result with a different code, and if it works well, then it's completely valid 05:54.280 --> 05:54.820 as well. 05:54.820 --> 05:57.940 Now the solution I provide will help you in three ways. 05:57.940 --> 06:02.740 First, if you are really stuck in one part, don't waste ten days being stuck. 06:02.770 --> 06:07.150 After some point, it's best to watch the solution and try to understand it. 06:07.180 --> 06:12.550 Second, after you finish the project, you can also see how someone else is thinking about the same 06:12.550 --> 06:13.300 problem. 06:13.300 --> 06:19.060 And third, I will try to give you a solution with clean code and best practices so you can use those 06:19.060 --> 06:22.660 tips to make your programs cleaner and more readable. 06:22.690 --> 06:24.910 All right, and let's start the project.
