a = arduino; readDigitalPin(a,'D13') ans = 1 Input Arguments collapse all Arduino hardware connection created usingarduino, specified as an object. Pin number on the physical hardware, specified as a character vector. Note If you are using an analog pin to read a digital value, thepinwil...
Set the logical value of a digital pin on the Arduino hardware: Sending1to the block input sets the logical value of the digital pin HIGH to 5 V or 3.3 V, depending on the board voltage. Sending0to the block input sets the logical value of the digital pin LOW to 0 V. ...
这是一个抽象函数，其作用是向指定的数字量接口写入数据。在这个例子中，要写入的数字量接口是LED对应的管脚，写入的数据是目标状态，亮或灭。
This example demonstrates the use of pinMode(INPUT_PULLUP). It reads a digital input on pin 2 and prints the results to the Serial Monitor. The circuit: - momentary switch attached from pin 2 to ground - built-in LED on pin 13 Unlike pinMode(INPUT), there is no pull-downresistorneces...
因此，digitalWrite(LEDpin, state) 函数的意思是，将 state 指定的电平写入 LEDpin 指定的数字引脚。在 Arduino 程序中，`serial.println(state)` 是一个函数，用于将变量 `state` 的值输出到串行端口。这个函数在 Arduino 中预定义好了，可以直接使用。`serial.println(state)` 函数会将变量 `state...
Reads a digital input on pin 2, prints the result to the Serial Monitor 从针脚 2 读取数字输入,并打印至串口监视器。 This example code is in the public domain. 此代码示例位于公共域中。 https://www.arduino.cc/en/Tutorial/BuiltInExamples/DigitalReadSerial ...

“GND”s because the bottom two pins are not labeled. But in fact the bottom most pin is VIN in official Arduino and “5VOUT” in Maker UNO. During one test I erroneously clipped the ground clip of my scope probe onto that pin, and BOOM, my USB hub turn itself off. So my board ...
