code (new) intpinRelay =5;//管脚D3连接到继电器模块的信号脚(TX) voidsetup() { // 为了提供串口显示,需要设置baud Serial.begin(9600); Serial.println("start test the electric relay the circuit..."); // 这一步不能忘记 pinMode(pinRelay, OUTPUT);//设置pinRelay脚为输出状态 //注意电压问题...
图中风扇部分电路(继电器负载部分)所标注的GND/5V 可以通过外接电源供电;也可以直接在单片机上的某对GND/VCC上。 风扇的可用性调试 风扇需要足够的电压来驱动,一般就接在5v(vcc/gnd) 但是风扇可以产生反电动势,对单片机可能造成损害,所以一般其中的一个管脚接在继电器的负载部分(您可以通过led等来调试继电器的可用...
