状态1：正常时，8个LED发光二极管（彩灯）循环点亮。 • 状态2：有报警时，蜂鸣器发出报警声（用P3.3接一个按键，模拟产生报警信号。当开关合上，发生报警；当开关断开，报警停止。用P3.7输出音频信号驱动扬声器，作为报警信号），同时8个LED发光二极管（彩灯）闪烁。 P3.2接一个按键，用于消除报警-Status 1: normal, eight LED light-emitting diodes (lantern) light cycle.

1256高频头遥控接收版本，利用红外头，普通的遥控器来接收改写频率，可以直接写需要解调的频率，外围电路十分简单，可以参考1256高频头资料，红外头只要和单片机连接上就行。-1256 high-frequency version of the first remote control receiver, using IR head, an ordinary remote control adapted to receive frequency, you can directly write the need for demodulation of frequency, the external circuit is very simple, you can refer to the first information on 1256 high-frequency, infrared, and as long as the first single-chip microcomputer connected on line.
