Arduino bluetooth trains at Monroe 2015
A short video showing the Arduino subway trains at the Monroe show in Monroe, WA, Feb 28-Mar 1, 2015. The infrared signals were flawless, but the trains acted erratically if their batteries got too worn down.
The laptop is an Acer Aspire One running Ubuntu 14.04, with a simple Perl script acting as train conductor to the two trains wirelessly via a USB 2.1 bluetooth dongle.
Each checkpoint is an Adafruit Trinket driving an infrared LED, powered by a 9v battery.
A clump of 2x6 brick was placed at the end of each track in the hopes they'd stop a runaway train. They were never really needed, but did get hit on occasion.
