Moving Rainbow
The Moving Rainbow is the name of our labs that use a bright and colorful LED strip to teach programming concepts.
The photo above is a 12-pixel version that is on a breadboard with a voltage monitor and a rechargeable LoPo battery. This project can be used in multiple locations and can be used to:
- See what happens when a battery is not plugged in
- See what happens when a GND or 5V wire is removed
- Teach the basics of a breadboard
- Show what the voltage is coming out of the Pico 3.3V pin
You can create your own Moving Rainbow kits for about $10 a kit. Each kit includes:
- A Raspberry Pi Microcontroller ($4)
- A 1/2 size 400-tie solderless breadboard ($1.50)
- A 3-terminal screw-header which is about (20 cents each)
- An LED strip with NeoPixels ($3)
We frequently purchase these parts in bulk to get discounts.
