Meet Sparky

Quick project last night to upgrade a skull with flickering red eyes. Steph had properly themed bouncy balls to go in the eye sockets.  I added some red LEDs and an ATTiny13.


I borrowed two different code snippets to make it blink with a nicer look.

Hackaday Link for project 1 (used the LCG formula)

Zenlogic’s PWM code (modified to use only two outputs)
