An Arduino as 16x function- and 6x servo-decoder

[RudyB]

An Arduino can be used as a combined function- plus servo decoder. This has a price tag under €5,- (including a fast opto-coupler).


Thanks to the people behind mynabay who made available the code for decoding the DCC commands. I added the software to control the outputs and the servos.


Here's a video that shows the Arduino driving a servo and a LED, controlled by the ECoS junction switch screen.

I recently installed, on my layout, an Arduino Uno (with additional circuitry on a protoshield) to control two servos used to position the two signal arms of a Tomar train order signal.

In my case logic level inputs to the Arduino came from existing DCC controlled hardware (part of the RR-CirKits Tower Controller system).
