Simple Automatic Kitchen Sink Light
Posted October 9, 2012 by Chris
“I decided to use an ATtiny84 as the heart of the project. It’s way under-utilized here, but I didn’t have any ATtiny25s in stock. I could have used a 555 instead of a microcontroller, but then I wouldn’t have gotten a cool fade-in and fade-out PWM effect. Plus the 555 at one minute or higher time scales is a little ungainly, with the high value capacitor required. And I REALLY wanted a smooth fade-in.”
