通用红外遥控系统由发射和接收两大部分组成，应用编/解码专用集成电路芯片来进行控制操作。本程序内容是：拨键开关置ON档时，红外发射模块发射数字（如发送1010 1010B），红外接收模块接收到的数据从I/O口输出来控制LED灯。-Universal infrared remote control system consists of transmitting and receiving two major components, the application of encoder/decoder ASIC chip to control the operation. Procedures are: When the dial key switch set to ON file, the infrared transmitter module transmitting digital (such as sending 1010 1010B) , infrared receiver module to receive data from the I/O port output to control LED lights.
