Hello there! If you are reading this book right now, it means that you've taken your first step to make fascinating projects using Arduinos. This chapter will teach you how to set up an Arduino and write your first Arduino code.

You'll be in good hands whilst you learn some of the basics aspects of coding using the Arduino platform; this will allow you to build almost anything including robots, home automation systems, touch interfaces, sensory systems, and so on. Firstly, you will learn how to install the powerful Arduino software, then set that up, followed by hooking up your Arduino board and, after making sure that everything is fine and well, you will write your first code! Once you are comfortable with that, we will modify the code to make it do something more, which is often what Arduino coders do. We do not just create completely new programs; often we build on what has been done before, to make it better and more suited to our objectives. The contents of this chapter are divided into the following topics:
