boolean buttonState = digitalRead(pushButton); digitalWrite(led, buttonState); 另外就是这个代码的效果是按下LED亮,松开则灭,我想改进一下,按一下亮,再按一下灭,代码如下: //按键开关控制LED灯,按一下亮,再按一下灭 const int buttonpin = 2;//button连接引脚 ...
在按键开关旁边再多加一路LED,LED的连接还是和以前一样(注意正负极),代码如下 //按钮控制LED的亮灭,按下亮,松开则灭 const int buttonpin = 2;//button连接引脚 const int ledpin = 13;//led连接引脚 void setup() { // put your setup code here, to run once: ...
