  Introduction to Arduino circuits and breadboarding What is Arduino? ●       Arduino is an open-source electronics prototyping platform built on user-friendly hardware and software. In a nutshell, Arduino is a prototyping board based on a microcontroller that can be used to create digital devices that can read inputs such as a finger pressing a button, a touch screen, a light on a sensor, etc., and turn them into outputs such as turning on an LED, turning on a motor, playing music through a speaker, etc. Fig 1: Key components of an Arduino board.                    [Source: https://docs.arduino.cc/learn/starting-guide/getting-started-arduino ]          1. Microcontroller - this is the brain of an Arduino, and is the component that we load programs into. Think of it as a tiny computer, designed to execute only a specific number of things.    ...
