This concludes our chapter on working with the Raspberry Pi 2 and the Arduino microcontroller.
Here, we learned how we could communicate over USB, GPIO, and I2C. This brought together some of the tasks we performed in earlier chapters.
Next is the final chapter of the book! Here we will build a project that uses some of the skills you have learned so far. You'll test your experience of working with GPIO pins, the Python programming language, and web development. Finally, you'll be presented with some ideas on how to expand your project further.
So let's get started.
