In many projects, it is very useful to get input from users. You need to be able to prompt the user for input, and then input that information into the Arduino. In most cases, users will not know how to program, so you need to have an easy way to interact with them. In earlier lessons, we showed how you can send messages or information from the Arduino using the Serial Monitor. In today’s lesson, we show you how to read input from the user through the Serial Monitor.

If you want to follow along at home, an official Arduino Uno R3 is available HERE. In this new series of lessons, I will be using the sensor and other components found in this KIT.
