Arduino Tutorial 11: Understanding the Arduino Serial Port and Print Commands

In this lesson we will learn how to print from the Arduino. Since you are often using the arduino to make reading from sensors or other devices that interact with the environment, you need an easy way to get that information out to the user. The easiest way to do this is to send it over a serial port to the IDE Serial Monitor. There, is can be easily read and watched by the user. In this lesson we show you how to configure the serial port, and send values from the Arduino. If you want to follow along at home, you can order the Arduino Kit we are using HERE.
