这是来自IDE的BlinkWithoutDelay示例程序: /* Blink without Delay Turns on and off a light emitting diode (LED) connected to a digital pin, without using the delay() function. This means that other code can run at the same time without being interrupted by the LED code. The circuit: * Use...
delay(20);if(buttonState==HIGH && buttonStateOld==LOW)//按钮状态发生变化{ buttonHoldTime= millis();//用millis()时间函数来记时,该函数最长记录时间为9小时22分,由于本程序最多记录60分钟,所以可以使用buttonStateOld =buttonState;if(onoff==HIGH)//当进入定时设置状态时{if(j>59) { j=0; timefix...

setDebounceTime(unsigned int time) Set the amount of milliseconds the keypad will wait until it accepts a new keypress/keyEvent. This is the “time delay” debounce method. 设置键盘将等待直到接受新的keypress / keyEvent的毫秒数。这是使用“时间延迟”防止抖动方法。 addEventListener(keypadEvent) Tri...
