Software
Firmware for this interface is available for download at https://github.com/Merdeka/Arduino-ModelRail. This
firmware needs to be compiled and uploaded to the Arduino using the Arduino IDE.
Search the Curious Timo YouTube Channel for tutorials and more information.

Hardware Pin Usage
There a few pins that are predefined for LocoNet or DCC usage. Please take care to not use the following pins
on the Arduino Nano in combination with LocoNet or DCC:
Digital pin 2 - DCC (Interrupt 0)
Digital Pin 7 - LocoNet TX
Digital pin 8 - LocoNet RX (ICP)

Schematics
In appendix A figure, A1 you will find the interface schematics. The schematics can also be found on GitHub:
