In this lesson, learn how to program the Pico to create a light show with multiple LEDs. Every light show needs a bit of a pause, so you will learn how to use the utime module to create delays. In the next part of the lesson, learn about multithreading with the _thread library. After completing this lesson, you will have mastered the basics and can go on to create other LED-based projects. For example, you could create a mini traffic light system or a night lamp.
