Description
Christmas tree ornament with (mostly) just a small number of through-hole components. Great for beginners. Might need a more experienced person to install the ATTiny841 and program it. There is an (optional) programming header to make in-circuit programming easy.
Unlike lots of other similar projects, the use of a micro-controller allows for smooth fading of the LEDs which makes for much more natural and pleasing animation. Also, unlike hardware-based flashing, software allows us to truly randomize the pattern.
