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。
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 side as the dat...

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...

This is a harder pill to swallow but it’s a necessary evil. For this to work the Arduino board emulates an Xbox 360 wired controller, which means it also borrows the use of Microsoft’s USB VID and PID so that the Windows driver will pick it up. Without this VID/PID combination the...
After installing a compatible boards package, you must thendownload and install the library. Once the XInput library is installed, open up the Arduino IDE and load an example sketch, located inFile -> Examples -> XInput(I suggest trying the 'Blink' sketch first). Double-check that you have...
經過實際測試,將微控制器的IO用20公分左右的線接出來,並設定成pull-up模式(這可以避免輕微的雜訊誤觸發),接條線出來當天線靠近引擎,IO準位也會隨之跳動,完全不用額外的電路或感測器。如此以來不用改裝原車線路,就能夠「隔空」得到轉速信號。在這邊將示波器時基設為50 ms/DIV、探棒設為1:1、垂直設為10 V/...
