From the course: Learning Arduino: Pulse Width Modulation

Challenges

- This course includes several videos called challenges. Challenges are quick activities that give you a hands-on opportunity to practice and master what you've learned. I'll start each challenge by describing your core objective for the activity. If the challenge involves using any sample files, I'll tell you where to find them. I'll also give you a rough estimate of how much time it should take you to complete the challenge. When you've completed a challenge, make sure to watch the matching solution video. In each solution, I'll show you how I solved the challenge and give you some of my thinking along the way. Again, this is an opportunity for you to master what you've been learning. It's also a great opportunity to have some fun.
