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
5without using the delay() function. This means that other code can run at the6same time without being interrupted by the LED code.78The circuit:9- Use the onboard LED.10- Note: Most Arduinos have an on-board LED you can control. On the UNO, MEGA11and ZERO it ...

在这种情况下,你不能使用delay(),因为Arduino程序会在delay()中停顿。 如果按键被按下的同时,Arduino正在暂停等待delay()结束,你的程序也将会错过按键的按下. 这个演示展示了如何闪烁LED而不使用delay()。它点亮了LED,然后记录下时间。然后,每一次通过loop()循环, 检查闪烁设置时间是否到达。 如果是,它的点亮或...
delay() 该命令告诉Arduino在 1000 毫秒或一秒内什么都不做。当您使用delay()指令,在这段时间内没有其他任何事情发生。 了解基本示例后,请查看BlinkWithoutDelay示例以了解如何在执行其他操作时创建延迟。 了解此示例后,请查看DigitalReadSerial示例以了解如何读取连接到电路板的开关。

OK now you are prepared! Open the Arduino IDE on your computer. Now you have to tell the IDE what board you are using, and how you want to connect to it. In the IDE find theToolsmenu. You will use this to select the board. If you switch boards, youmust switch the selection!So ...
There's 16 strips in all, wired very ingeniously in parallel so that the Arduino Pro Mini shield only has to deal with 8 channels. Each strip has a self adhesive backing that holds the strip solidly (during extreme head maneuvers) to the top hat. The + and - connections are created wit...
