ABSTRACT
Arduino is an open source hardware and is perhaps the most popular open source development platform. It consists of a microcontroller and an input–output system. Various versions of Arduinos are available in the market. Typically, the most popular versions of Arduino are Arduino UNO and Arduino Mega. Other versions such as Arduino Nano (version 2.X and 3), Arduino MINI v.04, and Lilypad Arduinos are quite popular in the market as well. Some of the latest models available are Arduino Leonardo and Arduino Duo. This single-board computer is the best choice for students, researchers, and hobbyists. The main objective of this chapter is to explore the Arduino hardware in detail.
