Summary
In this chapter, you learned how to interact with and use RGB LEDs, as well as how to choose and buy RGB LED strips that work with the Raspberry Pi. You learned how to make code for the LEDs on the robot, using them with robot behaviors. You also saw how the HSV color system works, which can be used to generate rainbows.
You can take the techniques used here to add LED-based status displays to robots and write code to link them with behaviors.
In the next chapter, we will look at servo motors and build a pan and tilt mechanism for moving sensors.
