Raspberry Pi Pico LED Badge

This project involves soldering. If you have little or no experience with soldering, make sure you have someone you trust walking you through the project. Always be in a properly ventilated environment when soldering, as it may release toxic fumes into the air.

What you’ll need:

- Raspberry Pi Pico
- About 30 LEDs, any color
- A piece of cardboard, it doesn’t have to be pretty as we are just using it as a template
- Power source, you can also just use the Micro USB cable and a battery pack

Tools you’ll need:

- Soldering Iron + Solder
- Pencil
- Micro USB cable
- A computer for programming the Pico
