In this chapter, we will take a look at how we can create an automated lighting system for indicating turns while biking. When biking in the dark, it can sometimes be hard to see when a cyclist indicates to make a turn or stop. This project will help in these situations by adding some light to the bicyclist's hands. The goal is to create a set of devices that work both with and without gloves, which can be worn on top of your hands. Since we have the advantage of using microcontrollers, we will also build these bike gloves so that they can detect if lighting is needed or not.

In this chapter, you will learn more about accelerometers, light sensors, and some more advanced coding. The chapter will also introduce the basic concept of gesture recognition and how to program for interactivity. We will also take a look at how to finalize you project and power the device using external power sources.
