An Arduino based Christmas tree decoration using basic electronic components and recyclable material.

Simulate a traffic light using an Arduino and LEDs! This project is super cool to watch and easy to make!

Use the cursor to change the colour of NeoPixels. Create light experiences using visual software like Photoshop or After Effects.

You’ll learn about IR protocol and how to use the IR receiver module.

This project allows the user to create their own light animations! Can modify each frame, the speed, and loop count.
