Pumpkin with PI symbol and Arduino-controlled Neopixel LEDs
Neopixels are individually addressable RGB LEDs. I bought an 8x1 array to try them out and decided they would make a good pumpkin light. Add an Arduino Nano, 4 AA's, a capacitor and a resistor and voila. Turns out you could see them from the street quite well.
The capacitor and resistor were added per Adafruit's Best Practices page for Neopixels.
