单片机PIC16F877A红外收发实验。使用串口发送数据经调制后从红外管输出，并通过红外接收模块把接收到的数据返回串口接收端，通过判断接收到的数据来控制LED灯点亮。-PIC16F877A microcontroller infrared transceiver experiments. After using the serial port to send data modulated output　the infrared tube, and through infrared receiver module converts the received data back serial receiving end, the data received by the judge to control the LED lights.
