CountDownTimer是一个便利工具,常用来处理倒计时场景。 importandroid.os.CountDownTimer;publicvoiddelayUsingCountDownTimer(intdelayInMillis){newCountDownTimer(delayInMillis,1000){@OverridepublicvoidonTick(longmillisUntilFinished){// 在这里可以处理倒计时的逻辑}@OverridepublicvoidonFinish(){// 这里是延时结束...

以下代码用 millis()函数来闪烁LED灯,如果开发板开始运行,会返回微秒的数值 /* 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 th...

In the previous tutorial, we learned to blink LED by using the delay method. That method blocks Arduino from doing other tasks. In this tutorial, we are going to learn another method to blink LED without blocking other tasks. The detail instruction, code

Using millis() admittedly takes a little bit of extra work when compared to using delay(). But trust me, your programs will thank you for it, and you can't do multitasking on the Arduino without it. If you want to see an example of millis() used in a real-world Arduino project, ...
