I just got back from vacation, and that left me with some tech-support catch up to do. I had a customer ask about some of our PID tuning software for the Motion Mind 3 motion control module which is pretty out of date.
An Arduino motor position controller can be built using an Arduino Uno and our Motion Mind 3 motor controller. This example describes how to interface an Arduino Uno with a Motion Mind 3 to create a closed loop motor position controller. This example and the associated code can be downloaded from our web site as Application Note 1008 (AN1008).
Last year I decided to build my kids a train set for Christmas and needed a simple train controller. Every Christmas my dad would break out the train set, and we would spend cold nights in the garage running plastic army men around the track on various missions. I wanted my kids to have fun like that. So I bought some tracks, a couple of engines, and some railroad cars off of eBay. Then I put together a wood base and paper mache tunnels. All I needed to complete the awesome holiday spectacle that is model trains was a train controller.
