Before Moving On
Make sure your circuit and code from this lesson work reliably before continuing to the next episode. Save your code so you can build on it in later lessons.
What’s Next?
In Lesson 10, you’ll use the potentiometer to control your rainbow effect and begin working with the servo motor.
