Märklin compatible & programmable with a magnet!

One area that many model train enthusiasts have never been totally happy with is the lighting of coaches. Until now. The lighting controller described in this article is a combination of an SMD LED strip and a PIC12F683 for compatibility with the Märklin system. The LEDs allow easy adaptation to different colours while three different lengths of the board enable the project to fit all common coach types. The controller can be assigned an address without removing it from the coach.


Quick Specs:
- Märklin compatible
- PIC12F683 microcontroller
- Free software
- PWM light intensity control
- 3 board sizes available for 4, 8 or 10 LEDs
- Adaptable to various colours
- ‘Live’ changing of decoder address
