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...
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...
unsigned long currentMillis = millis(); if (currentMillis - previousMillis >= interval) { // save the last time you blinked the LED previousMillis = currentMillis; // if the LED is off turn it on and vice-versa: if (ledState == LOW) { ledState = HIGH; } else { ledState = LO...
// the interval at which you want to blink the LED. unsigned long currentMillis = millis(); if (currentMillis - previousMillis >= interval) { // save the last time you blinked the LED previousMillis = currentMillis; // if the LED is off turn it on and vice-versa: if (ledState ...

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...
2.0.6– Added Travis CI unit and platform tests; getrnd() is mocked on platforms without time() or millis() is used instead 2.0.5– Restored backwards compatibility with AVR; updated Simple and Medium examples 2.0.3– Added unit tests; thus fixed getrnd() ...
