请勿转载！！！作品功能简介:当学习键按下后，红外接收头便可将接受到的信号存储到单片机中。
在接受到通用遥控器发出的信号后，如果按下发射键，单片机将调出刚刚储存的信息，通过红外发射头发射出和遥控器一样的信号来达到控制的作用。

51单片机设计的红外线遥控器电路图及工作原理
51单片机设计的红外线遥控器电路图及工作原理你家里是否有一个电视机遥控器或者空调机遥控器呢？你是否也想让它遥控其他的电器甚至让它遥控您的电脑呢？那好，跟我一起做这个“红外遥控解码器”。
该小制作所需要的元件很少：单片机TA89C2051一只，RS232接口电平与TTL电平转换心片MAX232CPE 一只，红外接收管一只，晶振11.0592MHz,电解电容10uF4只，10uF 一只，电阻1K1个，300欧姆左右1个，瓷片电容30P2个。
发光二极管8个。
价钱不足20元。
电路图及原理：主控制单元是单片机AT89C2051,中断口INT0跟红外接受管U1相连，接收红外信号的脉冲，8个发光二极管作为显示解码输出（也可以用来扩展接其他控制电路），U3是跟电脑串行口RS232相连时的电平转换心片，9、10脚分别与单片机的1、2脚相连，（1脚为串行接收，2脚为串行发送），MAX232CPE的7、8脚分别接电脑串行口的2（接收）脚、3（发送脚）。
晶振采用11.0592MHz，这样才能使得通讯的波特率达到9600b/s，电脑一般默认值是9600b/s、8位数据位、1位停止位、无校验位。
电路就这么简单了，现在分析具体的编程过程吧。
如图所示，panasonic遥控器的波形是这样的（经过反复测试的结果）。
开始位是以3.6ms低电平然后是3.6ms高电平，然后数据表示形式是0.9ms低电平0.9ms 高电平周期为1.8ms表示“0”，0.9ms低电平2.4ms高电平周期为3.3ms表示“1”，编写程序时，以大于3.4ms小于3.8ms高电平为起始位，以大于2.2ms小于2.7ms高电平表示“1”，大于0.84ms小于1.11ms高电平表示“0”。
因此，我们主要用单片机测量高电平的长短来确定是“1”还是“0”即可。
定时器0的工作方式设置为方式1：mov tmod,#09h，这样设置定时器0即是把GATE置1，16位计数器，最大计数值为2的16次方个机器周期，此方式由外中断INT0控制，即INT0为高时才允许计数器计数。
