Most of the larger projects that we create will use one or more LEDs as indicators. These LEDs can indicate things such as power, receiving data, warnings or anything else that we may need visual feedback for. We have already seen how to use a basic, single-color LED but what if we need multiple LEDs or even multicolor LEDs? In this chapter, we will look at other ways to add LEDs to your project.

In this chapter, you will learn:
