8-Way DCC Accessory Decoder for Peco Turnout Motors

Here’s a project from Viken Sheth that uses the NmraDccAccessoryDecoder_Pulsed_8 example sketch to drive a 16-way Relay Board, to then drive Peco Snap Turnout motors. The relays connect the Peco motors to a Capacitor Discharge Unit (CDU) and the sketch logic generates a short pulse to the relays so the Peco motor coils are only connected to…

DCC Controlled Turntable Stepper Motor Driver

Here’s an example of how you can use the new DCC Accessory Decoder PCB from Dcc Interface (in the UK) that combines an Arduino Nano, a A4988 Stepper Motor Driver module, an optical sensor and a DCC signal interface, to quickly let you drive Stepper Motors based on DCC Turnout Commands. I’ve written an example sketch that…
