Halloween is right around the corner. If you are looking for something that can be whipped together quickly and scare the pants off the kids that will be terrorizing the streets, look no further than these DIY Halloween LED Blinking Eyes by Pete Mills. The microcontroller code is available here.

“I connected the LED pairs to an ATtiny2313 microcontroller via some comms wire and some 2n3904 transistors for each pair. Since humans blink at about 3-4 blinks per minute when concentrating I figured that would be a good blink frequency to use for my creature eyes.  The creatures could in fact have once been human before turning, we just don’t know.  Blink duration is 350mS. “
