Using Serial Monitor & Plotter in Arduino IDE
A comprehensive step-by-step guide to communicating with your Arduino board and visualising data in real time.
The Serial Monitor is a built-in tool in the Arduino IDE that lets your computer communicate with an Arduino board over a USB connection. It displays text data sent from the Arduino and lets you send text back.
The Serial Plotter takes that same data and plots it as a real-time graph — perfect for visualising sensor readings, voltages, or any numeric value that changes over time.
Both tools use the same communication channel: the Serial port on your Arduino.
