To read data from the serial monitor, first, you need to check whether user entered data or not. To check user data availability, you need to useSerial.available()function/command. When the user enters the data on the serial monitor, Arduino setsSerial.available()to return ‘1’ and in ...

In this tutorial, I will be going through the steps on how to set up the Arduino serial monitor so you can debug and interact with a program running on the Arduino. This tutorial is pretty simple, but it can be a bit confusing at first especially if you’re new to programming and ...
