The Gurgle team has been making LED pumpkins ever year for about five years, but this year they've upgraded their project by using a Raspberry Pi PICO instead of a traditional Raspberry Pi. Their reasoning? You can power a PICO with just two AA batteries, while you have to have a larger power source for the Raspberry Pi.
This allows your pumpkin to be portable, or at least sit on display without having to be near an outlet.
The list of items needed is pretty short and inexpensive. The Gurgle team used:
- Microcontroller compatible with MicroPython (The Gurgle team used an RP2040 Pico)
- Two 8x8 LED Matrix with a backpack search for MAX7219 or HT16K33 driver chip
- Jumper Wire
