You've seen them - those "Apple computers." Probably in the hands of some Hipster in Portland, while riding his fixie and wearing those thick framed glasses. That pulsating light when Apple laptops are asleep is so ... sooooothing. You just want to go to sleep watching it. You know you do.
Today, we're going to replicate that using our ATTiny85. It's really easy, and most of it can be implemented in hardware instead of code (!!!).
Step 1: Supplies
- Breadboard wires
- 1 LED
- ATTiny85 (the 45 or 25 will probably work, but I haven't tested them)
- An ISP programmer (or other, if you know how to use it) - I use the USBtinyISP.
- A computer with avrdude and avr-gcc
- Optional: an oscilloscope
