Background.

This project is part of a larger project DCC-Yard_Control. It will be used to aid debugging during the code development and then as a display in the final project.

The Circuit

The design uses the LiquidCrystal_I2C library that assumes the I2C pins A4 and A5 on the Nano are used; That is**:
