-David Roberts gave two talks.
-John Fletcher talked about 'My MERG Journey'
+== So what is Arduino ==
+David Roberts gave a presentation to introduce the Arduino in terms of the hardware most commonly used by the Railway Modeller and the Integrated Development Environment (IDE). A look at Shields and other peripherals is included along with a very brief review of the standard interfaces.
+David's presentation can be found here [[https://merg.org.uk/merg_wiki/lib/exe/fetch.php?media=helpsystem:so_what_is_arduino.pdf]]
+== My MERG Journey ==
+John Fletcher talked about his expeirances since joining MERG

-Tony 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.
