WEBVTT 00:00.050 --> 00:03.620 This is step number four for this final project. 00:03.620 --> 00:08.360 And in this step we are going to add the email functionality in our program. 00:08.360 --> 00:10.760 So we already take a photo. 00:10.760 --> 00:13.670 After we detect a movement for more than five seconds. 00:13.670 --> 00:17.450 We also save the photo file names inside the log file. 00:17.450 --> 00:21.410 And now we're going to send also that photo by email. 00:21.410 --> 00:25.430 So let's start and let's initialize an email client. 00:25.430 --> 00:32.480 So with Gmail I'm going to import Gmail here for example here import Gmail. 00:32.480 --> 00:36.800 Then where do I set up my email for example here. 00:36.830 --> 00:39.530 Well you could do it wherever you want. 00:39.560 --> 00:46.220 I'm just going to do it here just after I create the global variables and to set up Gmail I will need 00:46.220 --> 00:48.800 the email address and also the password. 00:48.800 --> 00:50.960 And this is the password I have already saved. 00:50.960 --> 00:54.920 So in the previous lesson in the section on emails. 00:54.920 --> 00:59.000 So I'm first going to get the password from the file where I saved it. 00:59.030 --> 01:00.800 Let's add a comment here. 01:00.830 --> 01:04.810 Setup email and then password. 01:06.670 --> 01:08.350 So that's an empty string. 01:08.350 --> 01:09.010 And then I do. 01:09.040 --> 01:21.580 We've open and I have saved the password in home slash pi slash dot local slash share. 01:21.610 --> 01:26.650 Slash dot email password. 01:26.680 --> 01:27.160 All right. 01:27.190 --> 01:28.630 That's where I saved it. 01:28.720 --> 01:33.820 I'm going to open this with only read permission because I don't need more than that. 01:33.880 --> 01:41.170 And then as f for file and the password is going to be f dot read. 01:41.170 --> 01:44.770 And I'm also going to add dot a strip. 01:45.940 --> 01:46.240 Okay. 01:46.240 --> 01:50.980 Just to remove any unwanted space at the end or stuff like that. 01:50.980 --> 01:53.140 So we are sure that we only have the password. 01:53.140 --> 01:57.130 Then I can create my email client. 01:57.130 --> 02:05.610 Let's just name it YAG as we did before is equal to YAG mail dot SMTP uppercase. 02:05.640 --> 02:08.460 And that's going to be the email address you used. 02:08.460 --> 02:11.760 So the one you created as the sender of the email. 02:11.790 --> 02:12.000 Okay. 02:12.030 --> 02:20.400 So formula was course dot Raspberry Pi at gmail.com for you is going to be different. 02:21.180 --> 02:22.920 And then the password. 02:24.720 --> 02:31.740 Once we are done with this I can also do print email setup okay. 02:32.040 --> 02:32.490 All right. 02:32.490 --> 02:33.720 So the email is set up. 02:33.720 --> 02:40.080 Then what we're going to do is we're going to after here we take a photo and we update the photo log 02:40.110 --> 02:40.680 file. 02:40.680 --> 02:44.400 We are also going to send that photo by email. 02:44.490 --> 02:47.550 So let's create a function as we did before. 02:47.550 --> 02:58.830 Here I'm going to create a third function def send a photo by email for example. 02:59.700 --> 03:02.610 And I will pass as an argument the email. 03:03.830 --> 03:05.000 Uh, client. 03:05.000 --> 03:07.400 I could name it my client as I want. 03:07.400 --> 03:09.620 And also the file name. 03:09.650 --> 03:09.890 Okay. 03:09.920 --> 03:10.850 For the photo. 03:11.210 --> 03:15.830 And here, once again, I don't use the global variable directly. 03:15.830 --> 03:18.650 I'm going to pass the variable when I call the function. 03:18.650 --> 03:21.020 So then I get it as a parameter here. 03:21.020 --> 03:25.760 So I could basically export this function and use it anywhere else. 03:25.790 --> 03:31.250 And I will do Gmail client dot send. 03:31.670 --> 03:33.470 I will need to put two. 03:33.500 --> 03:37.700 So that's going to be your uh your email address. 03:37.700 --> 03:38.960 I'm going to change it later. 03:38.960 --> 03:43.700 But for now it's going to be your email address, the one you want to receive the email to. 03:43.730 --> 03:43.970 Okay. 03:44.000 --> 03:46.010 So that one here is a recap. 03:46.010 --> 03:47.540 This one is the sender. 03:47.990 --> 03:50.150 And this one here is the receiver. 03:50.150 --> 03:52.700 And then I put a comma I go to a new line. 03:52.700 --> 04:01.190 Subject is going to be let's say new photo from your from Raspberry Pi. 04:01.220 --> 04:03.020 You can write whatever you want. 04:04.330 --> 04:09.220 I'm gonna also add contents with an S, which is just. 04:09.220 --> 04:14.200 For example, check out the new photo. 04:15.700 --> 04:21.190 And then the most important thing attachment is equal to. 04:21.220 --> 04:23.050 And we directly have the file name. 04:24.220 --> 04:25.660 And I close the parentheses. 04:25.870 --> 04:26.260 All right. 04:26.260 --> 04:31.030 So we directly send the attachments that corresponds to the photo we have taken. 04:31.030 --> 04:34.870 So let's go to here. 04:34.870 --> 04:44.350 When we take the photo and we update the log file I'm going to then call send photo by email I'm going 04:44.380 --> 04:46.810 to provide a YAG. 04:46.840 --> 04:50.950 YAG is the YAG mail client I have created right here. 04:50.980 --> 04:51.640 Okay. 04:51.880 --> 04:55.720 Then I'm going to pass as the first argument here and then the file name. 04:55.720 --> 04:57.040 What is the file name? 04:57.040 --> 05:00.520 Well, this is the file name that I got right here. 05:00.520 --> 05:01.510 Photo file name. 05:01.510 --> 05:05.230 So photo file name. 05:05.230 --> 05:05.300 Finding. 05:05.420 --> 05:10.670 All right, so you see, what we do here is we call three functions one by one. 05:10.670 --> 05:17.300 And sometimes we even like here we even use the result of one function inside the following functions. 05:17.300 --> 05:18.530 I'm going to okay. 05:18.560 --> 05:28.100 This time I'm not going to save it as step three I'm going to do file save as step four okay. 05:29.120 --> 05:35.090 And before we run this let's do a very quick recap because that's going to be the end of that program 05:35.090 --> 05:35.930 here. 05:35.930 --> 05:41.570 So what do we have at the very beginning we have all of the imports for the modules we need to use. 05:41.600 --> 05:43.370 And we have three functions. 05:43.370 --> 05:49.010 We want to take a photo, one to update the photo log file and one to send the photo by email. 05:49.250 --> 05:49.550 All right. 05:49.580 --> 05:51.830 Then we have a bunch of global variables. 05:51.830 --> 05:57.230 And then well basically when we start to run this Python program is going to run all of the codes here. 05:57.230 --> 05:58.910 So it's going to set up the email. 05:58.910 --> 06:01.130 Then it's going to set up the camera. 06:01.730 --> 06:04.430 Then we remove the log file if there is one. 06:04.430 --> 06:06.460 We also set up the Gpios. 06:06.460 --> 06:08.920 And then well we have those two functions. 06:08.920 --> 06:14.680 So those two functions are here because they are directly related to all those callbacks here that we 06:14.680 --> 06:15.610 register. 06:15.610 --> 06:18.910 And in those functions we also use the global variables. 06:18.940 --> 06:19.120 Okay. 06:19.150 --> 06:22.630 So that's why I put them after all of this initialization. 06:22.660 --> 06:28.090 And so after we initialize everything we register the two callbacks and we pause the program. 06:28.090 --> 06:32.290 So we are just waiting for those events to happen. 06:32.440 --> 06:40.600 I'm just going to add a new log here just before we pause to say everything has been setup. 06:41.260 --> 06:41.470 Okay. 06:41.500 --> 06:43.300 So we know that's the end of the setup. 06:43.300 --> 06:49.240 And now to test the program I will need to write something valid here. 06:49.390 --> 06:49.690 All right. 06:49.720 --> 06:53.080 So I will replace that with my own email address. 06:54.880 --> 07:00.730 I'm going to save with Ctrl S and then let's run the program. 07:00.760 --> 07:00.970 Okay. 07:01.000 --> 07:02.560 So let's stop that one. 07:02.590 --> 07:05.320 Let's run the project step for. 07:07.380 --> 07:08.430 Email setup. 07:08.430 --> 07:09.090 Okay. 07:09.120 --> 07:09.750 Then you see. 07:09.780 --> 07:10.830 Camera setup okay. 07:10.860 --> 07:13.740 Previous log file removed Gpios. 07:13.770 --> 07:14.220 Okay. 07:14.250 --> 07:19.170 Everything has been setup, so let's make a movement for five seconds. 07:20.670 --> 07:24.630 Okay so it took a photo and you see sending it by email. 07:24.630 --> 07:27.570 We didn't get any error which means it probably worked. 07:27.600 --> 07:30.000 Now let's check the emails. 07:30.420 --> 07:33.600 And I just received a new email here. 07:33.600 --> 07:40.710 So the last one you see zero minutes ago and what is quite blur because I'm also moving my hand here. 07:40.770 --> 07:43.560 So that's the photo that I have received. 07:43.560 --> 07:46.320 You see new photo from Raspberry Pi. 07:46.350 --> 07:48.060 Check out the new photo. 07:48.060 --> 07:50.640 So it correctly worked. 07:50.640 --> 07:52.620 And every time you see I have a new one. 07:52.620 --> 07:59.280 So every time I receive a new photo here when there is a new movement detected. 08:00.060 --> 08:00.450 All right. 08:00.450 --> 08:02.640 And that's the end of this first program. 08:02.640 --> 08:04.050 So that's the end of step four. 08:04.050 --> 08:08.520 And then in the next step we're going to start the second program for this project.
