使用millis()进行计时 变成一个时间观察者 实现计时的一个简单技巧是制定一个时间表,并时刻注意时间。你只需定期查看时钟,这样你就知道什么时候该采取行动,而不是全部停止的延迟。与此同时,处理器仍然可以自由地执行其他任务。一个非常简单的例子是IDE附带的BlinkWithoutDelay示例程序。 本页代码使用的接线如下图所示...
1. 下载Aruino IDE 这里使用 2.0.3 版本。https://www.arduino.cc/en/Main/Software下载后安装。2. 准备Node-MCU开发板 二、设置 1. 填写开发板网址 点击 File-Preferences，到Additional boards manager URLs，填写：https://arduino.esp8266.com/stable/package_esp8266com_index.json点击OK。2. 开发板设置...

37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
IBusBM runs in the background using interrupts to ensure your code does not interfere with the iBUS timing. Timer0 is used by the core libraries on all Arduino AVR based boards to keep track of time for commands line millis() and delay(). IBusBM defines an additional interrupt on Timer ...
