例如,在 Arduino UNO 上使用 digitalPinToInterrupt(4) 将不起作用,因为中断仅支持引脚 2、3。 请参阅 attachInterrupt() 以获取所有板上支持的中断引脚的完整列表。 语法:digitalPinToInterrupt(pin) 参数:pin - 想要中断的引脚。 返回: 用于中断的引脚(例如2) 如果引脚不可用以进行中断,则返回-1。 程序示例:...
If the anode of the LED is connected to the Arduino pin, its cathode must be grounded so that the pin can serve as the current source. In such configuration, when the pin outputs a logical HIGH, the LED glows. When the pin outputs a logical LOW, the LED is switched OFF. If the ca...
一段Arduino代码,digitalWrite(pin,n[num][pin-3]); //为何要-3,请大... 因为pin是从3开始到10, 而数组n是个10行8列的二维数组,列是从0开始到7。 所以要pin-3,这样就是从0到7了。 人造草坪篮球场施工_环保无污染_专业施工_<奥奕康>17635718111_人造草坪施工 <奥奕康>专业从事塑胶运动场的造价、设计...

. Once opened, ask the Arduino to read the contents of the file with SD.read() and send them over the serial port. After all the contents of the file are read, close the file with SD.close() . Note that pin 4 is default Chip Select (CS) pin for most boards. To set CS for ...
Connect this to 3.3V on the MCU for 3.3V boards (Adafruit Feathers), or 5.0V for 5V Arduinos (Arduino Uno, etc.). 3Vo - This is the OUTPUT of the 3.3V regulator, and can be used to provide 3.3V power to other parts of your project if required (< 100mA). GND - Connect this...
"Digital" returns the value of the voltage at the pin while "Logic" returns the value of the input bit. Let us use a microcontroller to read a digital signal. Connect pin of an Arduino Uno to one side of a push button. Connect the same side thorough a pull down resistor of kΩ to...
