/*ButtonTurns on and off a light emitting diode(LED) connected to digital pin 13,when pressing a pushbutton attached to pin 2.The circuit:- LED attached from pin 13 to ground through 220 ohm resistor- pushbutton attached to pin 2 from +5V- 10K resistor attached to pin 2 from ground- ...
现在,需要常规的Arduino东西:我们定义按钮和LED的引脚,并将它们设置在设置功能内(这就是它的用途)。然后,我们需要定义状态图期望我们定义的函数-如前所述,- lightCtrl_setTimer 和 lightCtrl_unsetTimer 。在这里,我们只使用计时器服务,就完成了。现在,我们应该思考一下当达到 Light On 状态时实际上如何激活LED。
效果就是,当你每次按下或松开按键开关,都会打印相应的字符串,来显示当前的按键状态。而与此同时,Arduino UNO上的LED,也会在你每按四次按键更新一次状态。 13,502 文章标题:Arduino + 按键开关实现简单的计数器 - Arduino 实验室 固定链接:https://arduino.nxez.com/2018/07/07/arduino-pushbutton-switch-for-...
* Built-in LED on pin 13 Unlike pinMode(INPUT), there is no pull-down resistor necessary. An internal 20K-ohm resistor is pulled to 5V. This configuration causes the input to read HIGH when the switch is open, and LOW when it is closed. ...

9 如图所示连接硬件，按键连接到 D2 接口，电位计连接到 A0 接口，当判断 A0 的值大于 500 时，LED 闪烁；但是在按下按键时，会跳出循环，LED 停止闪烁。10 switch 语句判断执行输入下列代码：const int led = 13;void setup() { Serial.begin(9600); pinMode(led,OUTPUT);}void loop() { if(Serial....
