In this chapter, we worked with LEDs and servos. We controlled them with the code written directly in the Banana Pi and interacted with the hardware both through buttons and input on the script. Now, you should have started to see the potential of what can be accomplished.

In the next chapter, we will cover the process of interacting with sensors. We will explore infrared receivers that can be used in a remote control to control your Banana Pi. We will also explore the operation of prototyping hardware such as Phidgets, which can extend the Banana Pi, and take advantage of hardware such as RFID and light sensors to control the motors.

The following image shows the Phidgets RFID reader connected to the Banana Pi:

We will also explore the interaction with GPIO-connected hardware from the input over the USB.
