I'm using one right now to build a Fireman Sam dispatch console for my son. Lots of leds and buttons. An arduino would be better, except I want it to play MP3

- dividedbyzero 6y agoNeat project! There is a small, inexpensive MP3 player board called DFPlayer that can be controlled from an Arduino and probably would work well for similar use cases, if using a full Pi isn't an option.
- solution-finder 6y agoThat’s an excellent idea. Will you be writing a blogpost about it (please please)!
- hyperman1 6y agoI do something like this every few months, and I've never tought them worthy a blog, to be honest. It isn't particularly complicated. Base is a strong enough cardboard box from the local supermarket. I took screenshots of the console from an episode and cleaned them up with krita. Electronics is a matrix where some rows have leds abd others buttons. Software low level scans the matrix and drives leds and checks buttons. High level a state machine that changes state based on button presses. I mainly us whatecer I have lying around at the moment, and don't spend much money on components. The thing before this was a lego based crossroad with leds and an arduino
