Hi all,
I'm looking for a simple way to wirelessly transmit either a 1 or a 0. I want to flip a switch which sends say 2.5V to a transmitter. Then the receiver goes to 2.5V (or any 'high' value). Then one I flip the switch to 0V on the transmitter, and the receiver goes to 0V (or any 'low' value).
I don't need a far range. 10 feet would be the maximum. I am a bit concerned about noise and interference. This is where I kind of get lost. Because I don't want noise to give the receiver a false reading, does that mean I need to worry about encoding and decoding?
Is there such a thing as a simple transmitter and receiver like I'm describing or is it more complex involving encoding and decoding? Is there a product someone can point to?
Thanks for the help!
