The Design of Wireless Remote Control Transmitter
Abstract: According to the problem that traditional control mode can not meet the need of contemporary society. And that wired devices for remote control might bring hidden trouble. For reason given above, I put forward the view of the design of wireless remote control transmitter to solve the above problem. This paper mainly introduces the infrared remote-control transmitter which uses AT89C51 as the main part. In addition the design consists of buttons, nixie tube and power. After simulation and debugging in practical terms, the design has accomplished well and realizes the function of control in the distance. It makes people do something indirectly. The design has the advantages of small size, low cost, low power consumption and good practicability. The design also has a wide prospect of application.
