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...

I have been able to setup the Arduino IDE using board manager and upload the modified blink example below, such that GPIO 0, 1 and 2 should blink: Code: Select allvoid setup() { pinMode(2, OUTPUT); // Initialize the pins as an output pinMode(1, OUTPUT); pinMode(0, OUTPUT); ...
Using LED Strip and Blink examples with external WS2812B. I connect GPIO48 directly to the WS2812B led strip without resistor. GPIO sets to 48. So on-board LED and external WS2812B are connected to GPIO48. The WS2812B LED strip never turn on. But on-board always work!

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
