redTie

Custom wireless system built for Craftwife. The leds are to be sewn into real ties. There are 6 red leds per slave and each led can be dynamically controlled (PWM 0-255). All slaves run on battery (AA 3.6V lithium) and keep in contact with the master using 2.4GHz wireless transceivers (Nordic nRF24L01+). The maximum working distance is about ~80m (line of sight).
The master talks to SuperCollider via the RedTieMaster and RedTieSlave classes (usb-serial 115200 baud).
