Remote Overview
Been running for almost two years on the same battery! Surprisingly, the plastic is visibly worn where it's been rubbing under my radio.
- 8 buttons
- Powered by a coin cell
- uC is an rfPIC
- Receiver uses a PIC18F2520
I used a custom firmware to toggle test points on the receiver when buttons are pressed. I preserved all radio communications so I can still control the radio station or CD track (as if I'd ever want to).
