I just wanted a simle DCC central wich I can use to test new DCC locomotives n ad potentially with a “program” mode so it can “break in” new locomotives for me by running them for specific periods of time in both directions.Β Β The result is an ArduinoΒ based DCC central.Β Β Β It is based on some stuff I picked up from theΒ “interweb” and either slimmed it down or added new features.Β Β It uses an ATMel 328Β microcontroller chip , a 2 line LCD display, some LEDs, a potentiometer , some Pushbuttons and an oldΒ IRΒ remote controller from a tv set or video player.Β The signal from the Arduin o is boosted up by an LMD18200Β power motor driver chip on a pre built board from ChinaΒ (8 $)
The schematic below shows the setup.
