The main aim of this project is to utilize the application of the Arduino board to control the intensity of street light. As the traffic decreases slowly during late-night hours, the intensity gets reduced progressively till morning to save energy and so, the street lights switch on at the ...
In this complete tutorial you will learn how to use an LED with Arduino. First, you will setup your circuit with an Arduino board and an LED, and then discover different ways to control the LED.I will use Arduino Uno for the examples but the instructions here apply to any Arduino board...

37款传感器与模块的提法,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37种的。鉴于本人手头积累了一些传感器和模块,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,这里准备逐一动手试试做实验,不管成功与否,都会记录下来---小小的进步或是搞不定的问题,希望能够抛砖引玉。
为什么arduino的blink中pinmode是LED_BUILTIN而不是13号引脚。是因为LED_BUILTIN函数主要用来点亮Arduino主板内置的LED灯的，Arduino有不同的板型，主板内置的LED灯的引脚也有所不同，不一定都是13引脚。用LED_BUILTIN函数不管主板内置的LED灯是哪个引脚都回被点燃亮。
