"Blinking Eyes" LED circuit. ? Answered
A timer circuit that'll turn LEDs on and off in an approximation of eyes blinking. Ooooon-off-on-off-oooooon-off-oooooon. So, this coming Halloween, I've got a dozen or twenty of these timers, running pairs of red LEDs, about eye-width apart, that are poked through a piece of cardboard spray painted flat black and set in shadowed areas around the porch. Maybe a couple of sets of them covered with ping-pong ball halves to make the "eyes" bigger.
