Working on a nice blinky-light LED project for [http://ohm2013.org OHM]. Have a nice 'KITT-like' LED chaser on the front of my bike-rack + RGB led in headlight. ==Parts== * Digispark * PCA9685 (smd, soldered to breakout) * 16 bright LEDs (probably white) + suitable resistors * 1 RGB_LED * Power (probably a couple 3.7V 700mAh Li-Ion Nokia batteries) * Empty bike-light for Digispark+Batteries+RGB-LED * Some sort of enclosure * velcro for easy (dis)mounting on/from rack * ... ==Done== * solder smd PCA9685 to breakout * try [https://github.com/adafruit/Adafruit-PWM-Servo-Driver-Library Adafruit-library] on arduino * ported [https://github.com/dromer/Adafruit-PWM-Servo-Driver-Library/tree/TinyWireM said library] to TinyWireM. Now runs on Digispark. * made preliminary mashup-code for pwm-IC and onboard soft-pwm (soft-pwm now blinks ferosciously, have to debug). * ... ==Todo== * design power-system * make power-button * find suitable enclosure for LEDs and breakout * ... ==Other ideas== * Speed variation using hall-effect sensor for rpm-detection * Other animations * ...
