LEDfirefly Project

Posted September 17, 2013 by Chris

“I’ve made plenty of LED Throwies in my day but I only recently discovered Karl Lunt’s low power LED firefly project. I was immediately inspired to make my own LEDfireflies. Unlike LED Throwies which will only last 4 or 5 days per battery, these LEDfireflies utilize ATTiny AVR microcontrollers and the LED as a light sensor (cool!) to get several weeks of flashing on a single battery.”
