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,...

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...
