Abstract:In this paper, I proposed a remote control system over Bluetooth, in which a cellular phone can remote control other electronic machines. All cellular phone, computer and electronic machine (such as television) with internal or external Bluetooth can be used in this system. A cellular phone encodes the key event into control code, which is sent to the controlled terminal. The control code is decoded to control action by the controlled terminal according to the decoding scheme. Computer control function is achieved in the experiment.
