Working with Displays, LEDs, and Sound
To make robots more interactive and also help with system debugging, it is often helpful to let them display their status with light-emitting diodes (LEDs), displays, or audio output. This chapter will show you how to use different types of displays, LEDs, and speakers to build interactive robots and is structured as follows:
- Advanced use of LEDs
- Using different types of displays
- Adding sound output to your robot
We will see hardware and code examples that demonstrate all the techniques we cover in this chapter.
