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 the LED code. The circuit: - Use the onboard LED. - Note: Most Arduinos...
UNO板上标有L的LED。这段测试代码就是让这个LED灯闪烁。 插上USB线,打开Arduino IDE后,找到“Blink”代码。 通常,写完一段代码后,我们都需要校验一下,看看代码有没有错误。点击“校验”。 下图显示了正在校验中。 校验完毕! 由于是样例代码,所以校验不会有错误,不过在以后写代码的过程中,输入完代码,都需要校验...
以上code通过 if defined宏定义兼容两种开发板的板载LED PIN口,无需改代码 六、编译、烧录 点击“→”箭头,开始编译、烧录 首次烧录可能会慢一点,烧录成功会显示如下信息 烧录器会自动从flash引导,不出意外你的核心板上的小蓝灯将在一分钟之内开始 blink了 附上烧录的视频...

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

Arduino IDE提供了很多内建的范例，可以在开发板上直接编译、上传和运行。这里，我们以“Blink”为例进行第一次尝试。打开 “File” -> “Examples” -> “01.Basics” -> “Blink”:板载 RGB LED，预设“LED_BUILTIN”为绿色。将“LED_BUILTIN”更改为“LED_R”、“LED_G”或“LED_B”以获得红色、绿色...
