Examples of Arduino Applications in Embedded Development

Do you know what Arduino is? Do you know what Arduino can do? Today, let’s get to know Arduino!

Arduino is a convenient, flexible, and easy-to-use open-source electronic prototyping platform.

It includes hardware (various models of Arduino boards) and software (Arduino IDE). It was developed by a European team in the winter of 2005. Its members include Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, David Mellis, and Nicholas Zambetti.

This article shares a case of lighting up an LED using Arduino.

1. Connection of LED

LED (Light Emitting Diode) is a solid-state semiconductor device that can convert electrical energy into visible light. It directly converts electricity into light. The core of the LED is a semiconductor chip, one end of which is attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply, encapsulating the entire chip in epoxy resin.Note:
