Now that your setup has been completed, move into the main loop of your code. When your button is not pressed, the internal pull-up resistor connects to 5 volts. This causes the Arduino to report "1" or HIGH. When the button is pressed, the Arduino pin is pulled to ground, causing ...
参考文章1 参考文章2 arduino的引脚模式有三种: INPUT——输入模式 OUTPUT——输出模式 INPUT_PULLUP——输入上拉模式 Arduino 微控制器自带内部上拉电阻。如果需要使用内部上拉电阻,则应使用pinMode()将引脚设置为输入上拉(INPUT_PULLUP)模式。 上拉电阻 上拉电阻是当某输入端口未连接设备或处于高阻抗的情况下,...
INPUT PULLUP上拉 来自小钉锤WIKI 跳到导航跳到搜索 说明 Arduino 微控制器自带内部上拉电阻。如果你需要使用该内部上拉电阻,可以通过pinMode()将引脚设置为输入上拉(INPUT_PULLUP)模式。 注意:当Arduino引脚设置为输入(INPUT)模式或者输入上拉(INPUT_PULLUP)模式,请勿将该引脚与负压或者高于5V的电压相连,否则可能...
Pull up resistor Instead of using the internal pull up resistor from your Arduino board, you could decide to create the circuit yourself and add an external pull up resistor. Your circuit will look like this. Here I have simply added a 10k Ohm resistor between one leg of the button (same...

arduinoinput有电流。arduino的引脚配置有三种模式：输出(output)模式、输入intput)模式、输入上拉（intput_pullup）模式，当引脚设置为输出（(output）模式时，意味着Arduino可以向其它电路元器件提供电流，当引脚设置为输入（intput）模式时，引脚为高阻抗状态，有很小的电流，意味着Arduino可用于读取传感器...
pinMode()函数用于设置Arduino数字引脚的工作模式,其模式参数具体如下:1. **INPUT**:将引脚配置为输入模式,用于读取外部信号(如传感器输入)。2. **OUTPUT**:将引脚配置为输出模式,用于驱动外部设备(如LED、电机)。3. **INPUT_PULLUP**:将引脚配置为输入模式,并启用内部上拉电阻(解决输入悬空时电平不确定的问...
The INPUT_PULLUP option is a Teensy extension which is not present on the official Arduino. Active Low vs Active High Intuitively, most people think of a logic HIGH signal to mean "on" or "active" and a logic LOW signal to mean "off" or "inactive". This scheme is called "Active Hig...
