说明：  8路红外遥控开关控制器。 只用八路或少于八路时，可以用AT89C2051代替 AT89C51。一体化接收头输出端接P3.2(int0)， P1为控制输出端。P3.6接LED到地，可以扩展到 32路或更多！输出为高电平有效，需外加上拉电阻
(8-way infrared remote control switch controller. Only eight or less than eight, can be replaced with AT89C2051 AT89C51. Integration to receive the first output termination P3.2 (int0), P1 for the control output. P3.6 connected the LED to ground, can be extended to 32 or more! Output is high, need to pull-up resistor)
