Description

HALLOWEEN – JACK O’ LANTERN V2

After the success of my previous project – the Halloween – Jack O’ Lantern – many of you asked for something even more dynamic, with smoother flame transitions and more LED action. So here it is: Ultimate Fire Effect, a fully reworked version with improved hardware and software, driven by the tiny but mighty ATtiny85.

This project expands on the original flickering candle by adding six independently controlled LEDs, more realistic flickering, and even an optional magical blue flame effect inspired by Harry Potter. It’s perfect for pumpkins, lanterns, fantasy props, or spooky Halloween scenes.
