🌈 Distance Makes the Disco Grow Stronger

What happens when you wave your hand at a rainbow and it waves back?
In this beginner-friendly Arduino class, you'll build a colorful light show using an ultrasonic distance sensor and an RGB LED strip. As your hand moves closer and farther away, the lights will react in real time—changing brightness, color, or creating animated effects. It's part science experiment, part magic trick, and part tiny dance party.
Along the way you'll learn:

How ultrasonic sensors measure distance How to connect and control RGB LED strips
Basic Arduino programming concepts Using sensor data to create interactive projects

• How to customize colors and effects to make your project uniquely yours

No experience is required. If you can wave your hand and click "Upload," you're qualified.
Warning: Excessive use may result in dramatic hand-waving, unnecessary sound effects, and an overwhelming desire to put LEDs on everything. 🌈

If you have a laptop, please bring it — but come anyway if you don’t!
