Hi All

Im new to here.
I did up a heart rate circuit, and the output is a LED which will blink on very heart beat detected.

I've gotten myself a pair of 315mhz RF transmitter and receiver.

Is it possible that I output the circuit to the RF transmitter. then a LED to the receiver on a separate circuit, but will still blink on every heart beat.

How should i go about doing that?

Looking at the modules ,the transmitter has a data input which connects to your Ic2 pin 7, this should be transmitted to the receiver on the output pin which goes high to half the supply voltage and low, it should be in synchronization with your led.
