WEBVTT 00:00.300 --> 00:03.460 It's now time to start the final project of the schools. 00:03.990 --> 00:08.610 Congratulations already you have made it through all the sections of the class. 00:08.880 --> 00:11.540 You now have a very strong foundation. 00:11.760 --> 00:17.550 You can also use more advanced functionalities and interact with more hardware components. 00:18.030 --> 00:24.930 Now, this final project will be your first complete original project and a great opportunity to practice 00:24.930 --> 00:26.850 on everything you've seen before. 00:27.270 --> 00:28.900 So what is this project about? 00:29.640 --> 00:33.250 So this is the result you will get at the end of the final project. 00:33.540 --> 00:40.920 So this circuit right here is the circuit that you have build in the schools with all the components 00:40.920 --> 00:43.000 and you are going to use all the components. 00:43.410 --> 00:47.960 So this project is an interactive obstacle detection application. 00:48.270 --> 00:52.740 So you have the ultrasonic sensor here, which would measure the distance in front of it. 00:53.010 --> 00:59.490 And you can see I also print the distance on the LCD display screen as well as increase. 00:59.520 --> 01:01.740 Look at the yellow energy here. 01:02.040 --> 01:08.090 I increase the frequency, the frequency, the closer I am to the sensor. 01:08.490 --> 01:12.360 His breaking very fast here is blinking quite slowly. 01:12.580 --> 01:13.920 I also have a warning. 01:14.130 --> 01:18.620 If I get too close, that's less than 50 centimeters. 01:18.840 --> 01:26.190 And then if I get ready to close less than 10 centimeters, you can see we are in what I call the locked 01:26.190 --> 01:26.640 mode. 01:26.650 --> 01:30.870 So the applications locked against the obstacle price to unlock here. 01:31.140 --> 01:37.230 And then the two entities here right in yellow are blinking at the same time. 01:37.800 --> 01:40.160 OK, so now what are you to do? 01:40.170 --> 01:41.970 So remove the obstacle, OK? 01:42.120 --> 01:49.650 And then I need in order to unlock the application, I need to press here on the push button and now 01:49.650 --> 01:51.330 the application is unlocked. 01:51.660 --> 01:56.410 And I can if I want, I can unlock it again by going to close to the sensor. 01:57.480 --> 02:01.740 You can see here also that you have a green energy, which is Powelltown. 02:01.740 --> 02:09.000 So you have the photoresistor sensor which will measure the luminosity and the higher the the lower 02:09.000 --> 02:10.770 the brightness of the sensor. 02:10.950 --> 02:14.940 And of course, the lower the immunity, the higher the brightness. 02:14.970 --> 02:18.630 OK, so this is independent from the two other entities. 02:19.050 --> 02:23.970 And then so with the remote controller you can use also the remote controller. 02:24.180 --> 02:29.880 And when the application is blocked because of obstacles, so you can either pressing the button, but 02:29.880 --> 02:35.400 you can also press on the play button to resume the operation. 02:35.400 --> 02:38.250 And you can see the application is running again. 02:38.250 --> 02:45.150 Normally then what you can do is so you can see here that the distance is in centimeters if I press 02:45.150 --> 02:46.110 on the ECU. 02:48.360 --> 02:54.990 But you can see now I have the distance in inches so you can toggle between centimeters and inches by 02:54.990 --> 02:58.670 pressing on one button of the infrared remote control. 02:59.160 --> 03:04.990 And no, the thing is that this value is also saved inside the original with the April memories. 03:05.000 --> 03:09.990 So this is the settings that if I restore the audio with the reset button. 03:11.380 --> 03:17.040 So you see, so I have initializing for one second and then you can see we still have entries. 03:17.110 --> 03:20.820 OK, this was inside the April memorial. 03:21.790 --> 03:26.610 So you can keep default settings like this and now you have additional functionality. 03:26.630 --> 03:34.900 So if I toggle with the Ildong button, I can go see, for example, the luminosity, which is the relevance 03:35.560 --> 03:38.500 of the you can see of the photoresistor. 03:38.510 --> 03:40.320 I can put my hand. 03:40.330 --> 03:42.000 This is going to be lower. 03:42.780 --> 03:46.710 OK, you can see that you directly from the photoresistor stencil. 03:47.320 --> 03:54.750 And then I can also go to this screen which says Price off to reset the settings. 03:55.060 --> 04:00.670 And this I can place on the off button settings have been resits. 04:00.700 --> 04:07.400 Now, if I go back to the previous screen with the distance, I can see now the distance is in centimeters. 04:07.750 --> 04:14.530 So by going on the screen and pressing on the other button, I can reset all the default settings in 04:14.530 --> 04:15.370 the application. 04:15.850 --> 04:16.180 All right. 04:16.190 --> 04:18.460 So you can see that is a quite complete project. 04:18.730 --> 04:25.990 OK, first, the main functionality is to detect obstacles and to tell the secret all the robot or the 04:25.990 --> 04:33.820 application to look and to wait until a user has, for example, removed the object and manually unlocked 04:33.820 --> 04:34.600 the application. 04:35.050 --> 04:40.000 And to that, we add a few functionalities to improve the interactiveness. 04:40.030 --> 04:46.810 OK, so you can have more information with the LCD screen from the entity and also interact with the 04:46.810 --> 04:51.000 screen using the remote controller and the push-Button right there. 04:51.820 --> 05:00.060 And then we are also going to be able to use the simulation so you can see here the complete same Chicot 05:00.070 --> 05:02.440 on the simulation with the same component. 05:02.700 --> 05:10.750 I'm going to run the simulation so you will be able to do the project with the hardware, all with the 05:10.750 --> 05:11.380 simulation. 05:11.530 --> 05:14.570 And you can see the behavior is the same. 05:14.590 --> 05:17.980 So, for example, I can set different distance here. 05:18.280 --> 05:24.910 OK, we have one different 3D which blinks here and I can change here. 05:24.910 --> 05:27.610 You can see the unit. 05:27.940 --> 05:30.780 I can go to the different screens, OK? 05:31.060 --> 05:34.850 And you can see everything is the same as the real secret. 05:35.680 --> 05:43.330 So here you have the final results that you should aim to produce now to make it simpler to get all 05:43.330 --> 05:45.960 the specs and functionalities in one place. 05:46.150 --> 05:52.720 I have created a PDF for the project, which you can download as an additional resource of this class. 05:53.230 --> 06:00.250 Read the PDF to get all the specs and then start to work on the project and a few quick notes before 06:00.250 --> 06:01.240 you start the project. 06:01.270 --> 06:07.840 Well, this project is a little bit more challenging than any activities we have done before, but this 06:07.840 --> 06:09.220 is the way to progress. 06:09.400 --> 06:14.300 If you manage to finish it, you will be ready for any other future project. 06:14.740 --> 06:20.720 One very important thing is that you take enough time to work by yourself before watching the solution. 06:21.080 --> 06:23.860 That's the only way to improve your skills with algorithm. 06:24.280 --> 06:29.560 But then if you are really stuck at some point, don't stay stuck too long and don't feel bad about 06:29.560 --> 06:31.150 watching the next solution. 06:31.150 --> 06:32.550 Stick after this. 06:32.740 --> 06:38.830 Continue to work on your own and maybe come back to this particular step a few days after to do it again 06:38.980 --> 06:39.690 on your own. 06:40.030 --> 06:46.270 So I will provide a Complete Step-By-Step solution where I explain everything and give some best practices 06:46.270 --> 06:48.980 for your future projects for each step. 06:49.000 --> 06:53.620 You can also download the project code until that specific step. 06:54.050 --> 07:00.370 A few of the steps will be already familiar to you because that's very similar to what we've done in 07:00.370 --> 07:02.560 some previous lessons or activities. 07:02.830 --> 07:08.080 But in that case, I still recommend you write the code from scratch and do not copy and paste what 07:08.080 --> 07:09.760 we have previously done before. 07:10.370 --> 07:14.930 And finally, note that the solution that we give is just one solution. 07:14.950 --> 07:17.710 This is not necessarily the solution. 07:18.100 --> 07:25.480 You might end up with something different, but working as expected and this is totally fine now. 07:25.510 --> 07:30.100 Well, I guess this is time for you to start working on this final project.
