After some research, is it possible an encoding chip is needed on the transmitter? I am new to Auduino and was thinking that the controller would encode each signal from the software. The software is sound as others have used it with success with other sketches. I'm thinking it must be the code. I didn't write the code so I'm hoping someone here can verify it. Any help would be appreciated. If more info is needed please ask. I need to have this project working in two weeks. Thanks in advance - Steve.
