Arduino is an open-source prototyping platform based on an easy-to-use hardware and software. It consists of a circuit board containing a microcontroller and a ready-made software called Arduino IDE (Integrated Development Environment), which is used to write and flash the code to the microcontroller.
Arduino provides open-source standard libraries to ease the development of the code. So while developing an Arduino code, you don't have to care about the low-level embedded details, such as what should be written into the Registers of the Analog-to-Digital Conversion Module. You just need to learn the basics functions and to know how to use them.
This tutorial is intended for students, hobbyists, and makers. With Arduino, one can get to know the basics of micro-controllers and sensors very quickly and can start building prototype with very little investment. This tutorial is intended to make you comfortable in getting started with Arduino and its various functions.
With Arduino, you can get get started into microcontrollers and sensors rapidly and can begin developing prototypes with small budget. The aim of this to tutorial is to help you in getting started with Arduino and its applications.
