Topic: blink led, wirelessly (Read 598 times) previous topic - next topic

I need a very small, lightweight wireless LED circuit (that I can mount onto a cap/visor/mask) that can respond to an Arduino sending a blink signal. This is a low frequency, low-precision application - one or two blinks per second, triggered by the Arduino would be fine.  The transmitter will be 3-5 feet away, and the LED (and supporting receiving circuitry must be light and not encumber the mask - perhaps powered by a coin cell. There does not need to be any computation on the receiving side, just a reasonable response to the blink trigger.

Can anyone point me at such a circuit - I'm hoping there's a simple transmission and receiver circuit.
thanks!

i think IR is the way to go
note: make sure your reciving circuit has the same clockspeed, and is powerd(battery)

Perhaps this pair of modules would do the trick:
