Reads a digital input on pin 2, prints the result to the serial monitor This example code is in the public domain. */ 2. 变量定义 // digital pin 2 has a pushbutton attached to it. Give it a name: int pushButton = 2; 定义了一个变量pushButton,并将其赋值为2。这表示代码将操作数字...
Next, initialize digital pin 2, the pin that will read the output from your button, as an input: 然后初始化数字针 2,该针会动按钮读取输出,并作为输入: pinMode(2,INPUT); Now that your setup has been completed, move into the main loop of your code. When your button is pressed, 5 volt...
Arduino Mega 2560的数字IO引脚编号从0到53，其中0和1通常用于串行通信，而一些引脚还支持PWM输出。基本输入输出操作：输入操作：要将一个引脚设置为输入，可以使用pinMode函数，其中pin是你想要设置为输入的引脚编号。之后，可以使用digitalRead函数读取该引脚的电平状态。输出操作：要将一个引脚设置为输出，...

this code did work better for me than most others, with good explanation 中断样例(编码器中断主线程),使用两个外部中断。初始化读后,就不再读引脚的状态 更快读编码器:仅使用中断 我也在应用中使用到了读旋转编码器。经过多次尝试,我非常高兴快速大家有一个新的方式处理他们。依据前任的建议,我在AMT旋转编...
int val = 0; // variable to store the read value void setup() { pinMode(ledPin, OUTPUT); // sets the digital pin 13 as output pinMode(inPin, INPUT); // sets the digital pin 7 as input } void loop() { val = digitalRead(inPin); // read the input pin ...
Once the hardware part is done you need to upload the code to control the circuit. You can find the sketch in myArduinoPomodoroTimer github repo. The most complicated part of the code is setting up the interrupt handler. I took it from my other project where I built a digital clock usin...
