The electronic I chose is a remote control. Depending on which button you press, different signals are sent to the television. I believe this is due some sort of identical wiring that is located in the cable box. This is why it is called an electronic. The electric currents that are exchanged between the remote and the television are what enables channels to change and other remote control functions. Although this is solely a prediction, I am still very puzzled about how the remote and television communicate.
