 David Roberts gave the group a demonstration of three modules he has recently built:
-**A DCC Loco identifier**.  Originally developed by MERG member Duncan Greenwood.  The DCC loco identifier provides functionality that displays a locos identity at a button push.   While the decoder identifier may be built using an Arduino Uno and a motor shield this unit uses one of Duncan’s PCBs. The output is displayed on a 4-row 20 character Liquid Crystal Display (LCD) via an I2C interface.

 What is Arduino and what can it do for railway modellers
-David Thomas presented ‘A CBUS Sound Player’ in which he explained how the project has been inspired by Davy Dick’s sound player (See March 2017 journal and the subsequent threads on the Forum).  The set up uses three main components: an MP3 player, an Arduino and a MCP2515 CAN Bus. He then went on to explain how he configured the various sounds using FCU and also demonstrated how the whole thing connected together as a CBUS module.

I.e. 6 magnets giving a SSNSNS.  Tony then explained how he configured individual locos to establish which is North and then using an Arduino sketch to process the results and display the correct loco or vehicle identifier.
