The Arduino board is an easy to use microcontroller that can interface with a lot of electronics for the purpose of controlling these gadgets with minimal stress. The Arduino C programming language is the language of instruction for Arduino through which it interfaces itself with a computer. This book shows you how to compile the Arduino programming language and use it to control hardware attached to the Arduino USB. The python programming language is also handy for Arduino and it can serve as a basis for a lot of user-friendly Arduino projects. This eBook will also teach you all the basics that you need in python to be able to interface with your Arduino.
