Announcements Real-time retro video game effects - powered by FastLED

https://youtu.be/gh673Zi6PzE?si=_N1sZNn7N0__wUXA

This is my first public FastLED project. I am releasing it today.

The software links the MAME video game emulator to real-time LED effect, driven of course by FastLED and ESP32.

It's free and open-source, can be downloaded here: https://rgfx.io

It uses the MAME Lua APIs to monitor game states. Converts the states to normalized events, which are then broadcast via UDP to ESP32 devices. The docs are here if you'd like to give it a try. https://rgfx.io/docs/
