Are you looking for a simple electronic spooky project in time for Wednesday night? Well, Instructables user vatosupreme created these spooky blinking eyes that you can set up in a couple of minutes. You simply get a set of colored eyes that blink randomly using a ATtiny85 microcontroller, and an Arduino to program the eyes and hide them in your bushes.

Vatosupreme created the effect by making the eyes using ping-pong balls. He placed LED’s inside the balls and using wooden poles placed the balls in his bushes to trick unsuspecting tricker-treaters. Attached to the LED’s he has an ATiny85 microcontroller that is connected to an Arduino which interacts with each other simultaneously to deliver this “chilling” effect. IF you want to see the whole layout with the step by step instructions, check out his Super Spooky Evil LED Eyes of Doom Instructable!
