WEBVTT 00:00.080 --> 00:02.420 You have just finished the course. 00:02.450 --> 00:03.920 Congratulations. 00:03.920 --> 00:09.120 If you've made it until that point, it means that you also have made huge progress. 00:09.140 --> 00:15.740 You can now apply your knowledge to any project of your own or start any other project from scratch. 00:15.740 --> 00:21.770 And before we wrap things up, just a quick recap on how to build an application with both Raspberry 00:21.770 --> 00:23.090 Pi and Arduino. 00:23.120 --> 00:29.000 The step by step process is kind of a best practice you can follow, which will help you progress faster 00:29.000 --> 00:30.380 when doing a project. 00:30.380 --> 00:38.030 So once you have a project ID, start by finding what functionalities do you need to implement in order 00:38.030 --> 00:39.410 to achieve the project. 00:39.410 --> 00:45.860 Then from those functionalities, choose which ones are going to be on the Arduino side and which ones 00:45.860 --> 00:52.520 are going to be on the Raspberry Pi side for some functionalities like taking a photo with the Pi camera, 00:52.520 --> 00:58.490 well, this is kind of obvious, but for other functionalities is going to be quite challenging to know 00:58.490 --> 01:02.940 on which side you should implement them to correctly choose. 01:02.970 --> 01:09.480 Remember that the application logic is on the Raspberry Pi and the execution of hardware command is 01:09.480 --> 01:10.410 on the Arduino. 01:10.500 --> 01:16.530 And well, if you realize that you need to change one functionality later on when doing the project, 01:16.560 --> 01:17.520 no problem. 01:17.520 --> 01:17.710 Okay. 01:17.760 --> 01:19.200 You can still modify it. 01:19.200 --> 01:25.860 After that, the functionalities are clear to you and you know on which side they are going to be implemented. 01:25.860 --> 01:29.420 Then it's time to define a communication protocol. 01:29.430 --> 01:35.220 Basically what commands and messages you are going to send and receive on both sides. 01:35.220 --> 01:40.470 It's important to do this now so you know what to do when you are going to write the code. 01:40.620 --> 01:44.280 And finally, we arrive at the coding part. 01:44.310 --> 01:47.790 At this point, you have a good idea of what you need to do. 01:48.000 --> 01:54.240 I recommend you start with the Arduino code, implement the Arduino functionalities and with serial 01:54.270 --> 01:58.350 send some messages and process the comments that you receive. 01:58.380 --> 02:01.110 If you correctly down the previous steps. 02:01.110 --> 02:04.770 This should not be hard to do when writing the Arduino code. 02:04.770 --> 02:07.230 You can debug using the serial monitor. 02:07.260 --> 02:12.930 Once this part of the application is working, then write the code on the Raspberry Pi. 02:12.960 --> 02:18.900 You will implement the functionalities that are specific to the Raspberry Pi and also the application 02:18.900 --> 02:19.590 logic. 02:19.620 --> 02:26.610 I suggest you iterate on the code one step at a time with a clear intermediate goal where you can see 02:26.610 --> 02:33.510 a real result after you've done and tested one step right the next one until you finish the application. 02:33.510 --> 02:40.830 And well, if you follow this work structure, you should be able to create any product you want in 02:40.830 --> 02:41.760 no time.
