RF Transmitter/Receiver (#27980)
Hi, I was wondering if anyone could help me out quickly. I am using the Basic Stamp 2 with the RF Transmitter/Receiver. Is there anyway that I can send a signal/code to the transmitter that makes it send out a certain signal to be picked up by the receiver. We only have 1 set of transmitter/receiver so we cannot send a signal to one transmitter to receiver to transmitter...
Thanks for any help!

Keep in mind that there may be a lot of radio noise present and there may be errors in the information received. It's good practice to use some kind of error detection. There are some examples with links on the product webpage on the use of CRC (cyclic redundancy checks) with the transmitter/receiver. The use of "!" or similar lead-in character also helps. In simple cases, you could just send the same data two or three times with different lead-in characters to get the redundancy.
