Hi S.P.S,
Thanks for the info. When you say 2nd pin, I assume its data pin next to GND.
I have one more question.
I believe that whatever data I send at data pin of transmitter, is available at data pin(pin2) of receiver. We dont have to bother about demodulation or modulation.
Suppose while transferring a data from a port pin of micro-controller to another port-pin of a microcontroller, instead of a wire, i can put this transmitter and receiver in between and connect the port pin of first MC to Tx data pin and port pin of second MC to data pin of receiver. And it works as before.
Am i correct??
