我们也需要您的输入基于delay()的计时的另一个问题是,用户输入(比如按钮按下)往往会被忽略,因为处理器无法在delay()中检查按钮状态。使用基于millis()的计时,处理器可以定期检查按钮状态和其他输入。这使得我们可以构建复杂的程序来做很多事情一次,但仍然保持反应。我们将通过向电路中添加一个按钮来演示这一点,如下...
To overcome the problem caused by using delay, a developer should usemillis()function which is easy to use once you become habitual and it will use 100% CPU performance without generating any delay in executing the instructions.millis()is a function that just returns the amount of milliseconds...
We won't mess with the freqency of Timer0, because that would break millis()! Comparison Registers Arduino timers have a number of configuration registers. These can be read or written to using special symbols defined in the Arduino IDE. For comprehensive description of all these registers ...

For example, they will allow you to write multitasks programs very easily, and thus avoid using the delay() function.Here’s an example of a typical program using millis()/micros():unsigned long previousTime = micros(); // or millis()...
