In this video, I demonstrate how to set up a circuit and code that interacts with the Arduino serial monitor. This setup will show you the basics of interacting and collecting data to and from the Arduino.

In this tutorial, we will build a simple circuit that consists of an Arduino Uno, a 100-ohm resistor, one red LED, a breadboard, and a breadboard wire. This circuit aims to show how you can receive and send data over the serial port.
The equipment that I used is listed below. Please note that we may earn an affiliate commission if you buy through our links.
Arduino Uno: amzn.to/4bQkFyM
Breadboard: amzn.to/4bLzVwX
Breadboard wire: amzn.to/44SJhVq
100-ohm resistor: amzn.to/3VaYMos
LEDs: amzn.to/3KdsEKI
The code we use in this tutorial is straightforward and aims to show you how to use the Arduino serial monitor. Debug lines are essential if you’re having trouble with your code.
As I explained in the video, the serial monitor window is easy to navigate and only has a few options you may need to tinker with. For example, the baud rate must be set to the rate you set in the code. If you don’t do this, your output will become gibberish.
I hope you have learned all the basics about the Arduino serial monitor in this video. If I have missed anything, got something, have feedback, or anything else, then please leave a comment below.
