LED Fire Kit
This \(10 kit uses a NeoPixel ring to simulate a small tabletop fire. It uses a NeoPixel ring (\)5), a low-cost (4) Raspberry Pi Pico, a breadboard, some wires and a power supply. The power supply can be a battery pack with 3 AA batteries or a 5v USB wall adapter.
If you don't have a breadboard you can solder the components together on a perfboard.
