The sketch below is based onLimor Fried's version of debounce, but the logic is inverted from her example. In her example, the switch returns LOW when closed, and HIGH when open. Here, the switch returns HIGH when pressed and LOW when not pressed. 下面的代码基于 Limor Fried 版本的去抖,...
// 检测按下(LOW 状态)且避免重复触发(消抖) if (digitalRead(momentaryPins[i]) == LOW && (currentTime - lastMomentaryTime[i] > debounceDelay)) { // 根据实际需求,你可以映射到任意键值;此处以 'a', 'b', 'c', 'd' 为例 char keyToSend = 'a' + i; Keyboard.press(keyToSend); delay...
20K-ohm resistor is pulled to 5V. This configuration causes the input to read HIGH when the switch is open, and LOW when it is closed. created 14 March 2012 by Scott Fitzgerald http://www.arduino.cc/en/Tutorial/InputPullupSerial This example code is in the public domain */ void setup(...

The solution to make the Arduino toggle switch work is...Debouncing.There's are many ways to debounce a switch which are described in the easy switch debounce page. The one chosen below is the simplest but uses the delay function so it wastes processor time to perfborm the deounce. Better...
long debounceDelay = 50; // the debounce time; increase if the output flickers void setup() { pinMode(buttonPin, INPUT); pinMode(ledPin, OUTPUT); // set initial LED state digitalWrite(ledPin, ledState); } void loop() { // read the state of the switch into a local variable: ...
delay(15); // software debounce if (digitalRead(button) == HIGH) { // if the switch is HIGH, ie. pushed down - change the lights! changeLights(); delay(15000); // wait for 15 seconds } } } 应该这样做。您可能想知道为什么按钮检查会发生两次( digitalRead(button)),并间隔一小段时间。
delay(100); // Wait for button debounce while (digitalRead(buttonPin) == LOW) {} // Wait...
// check and debounce buttons if (digitalRead(pin) == HIGH) { delay(10); if (digitalRead(pin) == HIGH) { return true; } } return false; } void doAction(int pin) { // perform tasks switch (pin) { case 2: Keyboard.println(“drive.google.com”); ...
