+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. Using Alan Turners pcb (See PCB section of the knowledgebase) 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.

+.
+Tony Jackson gave the second talk entitled ‘A Magnetic Identity’ in which he introduced the use of magnets to obtain the identity of a loco or vehicle (rather than only detecting its presence) to facilitate effective decisions regarding automating aspects of layout operation.   Tony explained that by attaching magnets to the base of a loco or vehicle and passing in turn over a linear Hall sensor represented a code that could be configured as a specific identifier. 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.
