A lot was covered in this chapter. By the end of it, you should be feeling pretty good about developing applications on the Raspberry Pi.
The picamera, Pillow, and sense-hat libraries make it easy to communicate with the outside world with your Raspberry Pi. Using the Raspberry Pi camera module and picamera, we open up a whole new world of possibilities with our Pi. We only touched on a small part of what picamera can do. Additionally, we only scratched the surface of image processing with the Pillow library. The Sense HAT emulator allowed us to save spending money on buying the actual HAT and test out our code. With sense-hat and the Raspberry Pi Sense HAT, we truly expand our reach into the physical world.
The inexpensive Pibrella HAT provided an easy way to jump into the physical computing world. By installing the pibrella library, we are giving our Python code access...
