NOTE: This Gist was an early write-up of this blog post, part of what became an eleven-part series on my arcade cabinet. I'd suggest you read that post instead of this, but some of the comments on this Gist contain updates and field reports that you might find useful.
RetroPie, LED control, and you
I wanted LEDBlinky-style functionality out of my RetroPie cabinet. But I didn't need RGB control or magical frontend integration or anything like that. I had buttons with simple single-color LEDs.
I've got a simple control panel with six buttons per player. All I wanted was this:
- When I launch Street Fighter 2, all twelve buttons should light up.
- When I launch The Simpsons, only the first two buttons for each player should light up.
