Chapter 8. Communicating with Others

Until now, all our projects have been designed to be standalone and independent, but there will be occasions where we will have to integrate our project with other external devices, and this means that we will have to make our Arduino talk with these other elements. Usually, this communication is made via a very practical and extended standard called serial communication.

In this chapter, we will see how to connect and program Arduino so that it is capable of serially talking to our computer as the simplest and most common type of serial communication, but what you will learn here is directly applicable to any other connection you have to establish to another device that can talk serially.

So, let's give up talking and let's make our projects talk.
