2、数字输入上拉 DigitalInputPullup - 输出上拉串口 InputPullupSerial This example demonstrates the use of INPUT_PULLUP with pinMode(). It monitors the state of a switch by establishingserial communicationbetween your Arduino and your computer over USB. 本例演示如何使用 pinMode 和 INPUT_PULLUP。

2、输入(INPUT)模式 3、输入上拉(INPUT_PULLUP)模式 (仅支持Arduino 1.0.1以后版本) 在输入上拉(INPUT_PULLUP)模式中,Arduino将开启引脚的内部上拉电阻,实现上拉输入功能。一旦将引脚设置为输入(INPUT)模式,Arduino内部上拉电阻将被禁用。 设置Arduino引脚为输出(OUTPUT)模式 当引脚设置为输出(OUTPUT)模式时,引脚...
pinMode(Button1, INPUT);//按钮1引脚设置为输入 pinMode(Button2, INPUT_PULLUP); //按钮2引脚设置为输入上拉模式 } void loop() { // 读取输入引脚的值 boolean button1State = digitalRead(Button1); boolean button2State = digitalRead(Button2); ...
pinMode(BUTTON_PIN, INPUT_PULLUP); } voidloop(){ Serial.println(digitalRead(BUTTON_PIN)); delay(10); } If you run this code and open the Serial Plotter, you’ll see that the default value is 1 (HIGH). When you press the button the state directly goes to 0 (LOW) and comes back...
INPUT_PULLUP 输入上拉模式 Blink程序中使用到的pinMode(LED_BUILTIN, OUTPUT): 即是把LED_BUILTIN(13号)引脚配置为输出模式 配置成输出模式后,还需要使用digitalWrite() 让其输出高电平或者是低电平。其调用形式为: digitalWrite(pin, value); ...
pinMode(2, INPUT_PULLUP); //Button 1 with internal pull up to chage track pinMode(3, INPUT_PULLUP); //Button 2 with internal pull up to play/pause pinMode(3, INPUT_PULLUP); //Button 2 with internal pull up to fast forward ...
pinMode(2, INPUT_PULLUP); // initialize control over the keyboard: Keyboard.begin(); } void loop() { while (digitalRead(2) == HIGH) { // do nothing until pin 2 goes low delay(500); } delay(1000); // new document: Keyboard.press(ctrlKey); ...
