I'm currently playing with the Arduino microcontroller much beloved of hobbyists and gadgeteers: http://arduino.cc/
Pleased with what I can make it do so far, which is program it (in C), but not communicate through my Mac with its running program. It has a USB port which supports a simple TTY interface via which commands can be sent and data retrieved. Does anyone have any experience of communicating with it using J?
