arduin去除按键长按接收信号

您好,我可以明白您的问题是关于如何在arduino中去除按键长按接收信号。一种解决方法是在编写程序时使用一个计时器来检测按键被按下的时间,并在一定的时间间隔内判断按键是否释放。如果按键一直被按下,则可以忽略该按键的信号。另外,您还可以使用外部硬件电路来处理长按信号,在按键被按下一段时间后,将其信号传递到arduino中。希望这可以帮助您解决问题。

arduino按键长按不接收信号只接收短按代码参考
我可以为您提供参考代码,请参考以下示例:
```
const int buttonPin = 2; // the number of the pushbutton pin
int buttonState = 0; // variable for reading the pushbutton status
unsigned long buttonStartTime; // variable to store the start time of button press
void setup() {
pinMode(buttonPin, INPUT_PULLUP); //set input pin with pull-up resistor
}
void loop() {
buttonState = digitalRead(buttonPin); // read the state of the pushbutton
if (buttonState == LOW) { // button is pressed
buttonStartTime = millis(); // record the start time of button press
while (digitalRead(buttonPin) == LOW) {
// wait for button release or timeout
if (millis() - buttonStartTime > 5000) {
// button is held for more than 5 seconds
// do something here
break;
}
}
if (digitalRead(buttonPin) == HIGH && millis() - buttonStartTime >= 50) {
// button is released and held for more than 50ms
// do something here
}
}
delay(10);
}
```
这个代码告诉 Arduino,当按键被按下并保持按下超过 5 秒时,执行某些操作。如果按键被按下并松开,且按下时间超过 50 毫秒,则执行另一些操作。您可以根据需要对代码进行更改。
arduino遥控器按键长按不接收信号的代码
很抱歉,我无法提供您所需的代码。但是,您可以尝试使用以下代码,看看是否能够解决问题:
```
int buttonPin = 2; // 按钮引脚
int buttonState = 0; // 按钮当前状态
int previousState = 0; // 按钮之前状态
long startTime; // 长按开始时间
long holdTime = 1000; // 长按时间阈值
void setup() {
pinMode(buttonPin, INPUT_PULLUP);
Serial.begin(9600);
}
void loop() {
buttonState = digitalRead(buttonPin);
if (buttonState == LOW && previousState == HIGH) {
startTime = millis();
}
if (buttonState == LOW && (millis() - startTime > holdTime)) {
Serial.println("长按按钮");
// 在这里添加长按按钮触发的代码
while (digitalRead(buttonPin) == LOW) {}
delay(50);
}
previousState = buttonState;
}
```
这段代码使用了 millis() 函数来检测长按的时间是否超过了设定的阈值,如果超过了,就触发相应的代码。您可以将该代码添加到您的 Arduino 遥控器代码中,看看是否能够解决问题。
