Pumpkin Halloween

🎃 Halloween Pumpkin PCB (ESP32-C3)

This is a double-sided decorative PCB shaped like a Halloween pumpkin.

• Front side: only multicolor silkscreen artwork (clean, no components).

• Back side: all electronics are hidden on the rear.

Light + sound

• 7× WS2812B RGB LEDs on the back illuminate the eyes, nose and mouth through the design.

• An ESP32-C3 runs the LED animations and drives a buzzer with Halloween-style melodies.

• The LED effect is symmetric (paired LEDs mirror each other), and the animation is synchronized with the melody.

Power note (USB)

This project can be powered from a computer USB port, but users must consider peak current:

• WS2812B LEDs can draw high current depending on brightness and color.

• Recommended: keep brightness limited or use an external 5V supply (≥1A) for safe margin.
