Button(pin, dbTime, puEnable, invert); Required parameter pin:Arduino pin number that the button is connected to(byte) Optional parameters dbTime:Debounce time in milliseconds. Defaults to 25ms if not given.(unsigned long) puEnable:trueto enable the microcontroller's internal pull-up resistor,...
Debounce Really small Arduino library for button Debouncing. It's basically the Debounce example found on http://arduino.cc/en/Tutorial/Debounce wrapped as a library. Really easy to use, with examples included. Tested on an Arduino Due only. Instructions Include the library in your sketch: #in...

我把函数名称setDebounceTicks 换成setDebounceMs(),就不会报出一堆红色字了,其他几个同样调整就解决了。 有了上面这些新知识,继续完善小夜灯这个项目! 再四十八的基础上增加下图圈起部分内容: 继续新增声明,setup函数同之前的描述: 下面是loop函数部分,button1.tick()函数一定要放到前面,再弄其他的动作。
int _pin; // hardware pin number. unsigned int _debounceTicks = 50; // number of ticks for debounce times. unsigned int _clickTicks = 400; // number of msecs before a click is detected. unsigned int _pressTicks = 800; // number of msecs before a long button press is detected ...
intbuttonState =digitalRead(buttonPin); if(buttonState ==LOW&&millis() - buttonDebounceTime > debounceDelay) { buttonDebounceTime =millis();// Reset debounce timer if(currentLED == middleLED) { Serial.println("You win this level!");
Button:使用按钮控制LED。 Debounce:读取一个按钮状态,过滤噪音。...5.控制结构 Control Structures Arrays:For循环示例的变体,演示如何使用数组。 For Loop Iteration:使用for循环和控制多个LED。...String Replace:替换字符串中的单个字符。 String Start With Ends With:检查给定字符串的开头或结尾字符/子字符串。
