It plays a certain role in the industrial, medical, agricultural production, aerospace, household appliances and other equipment for wireless remote control. The design includes the followings :The design of wireless multi-channel remote control launching system not only provides the hardware circuit design and coding device structure, described in detail the design of hardware circuit elements and it makes a various components of the structure and the main performance, more comprehensive introduction of the control circuit encoding technology In the control side of this design uses 4 * 4 keyboard for touch and pressure-type single input signal, then the signal will be input to the AT89C51 microcontroller code to implement multi-channel remote control and display the generated signal through the digital display the generated signal. Signal transmission circuit is based on the launch of MC2833 microcontroller circuit, and this design provides a detailed description and specific design principle of the circuit. The design of the project and its control circuits are generally more suitable for simple remote control system design, h
