Arduino IO Simulator Windows

You bought an Arduino, What now?


This Arduino Simulator is different than all the other simulators. If you don’t have components like sensors, LEDs..., then this program will simulate the components for you. You need a real Arduino board for testing your programs with your computer and just change some codes to work with the simulator components.


The Simulator has a lot of components that are required to test your projects.



Also available for MacOS.

Arduino IO Simulator


Designed for people in hardware need!


The Arduino Simulator has been drastically changed the way you use a simulator. By communicating with the Arduino board we can simulate your IO on your screen. To make everything as easy as possible we created libraries that handles everything for you.

This Arduino Simulator is designed to optimally simulate your (IO) projects with the aim of testing your projects without components if you don't have some parts yet you can simulate them.

The Arduino Simulator has many components built in to test your projects. 


  • 14 LEDs (4 colors, customizable)
  • 8 buttons
  • Squarewave generator
  • Buzzer (Frequency adjustable)
  • Noise detection (microphone)
  • 3 sliders (analog)
  • 7-segment display
  • LCD display (16-2)
  • Bargraphs
  • Tone melody
  • Sound generator (frequency changeable)
  • Servo motor
  • Serial Monitor

The simulator supports English, French, Spanish, German and Dutch.

Simulate your IO

A simulator made for beginners

This simulator is designed for beginners who want to test their program quickly or don't have the necessary electrical parts.


Write your project in the Arduino IDE. Add the Simulator library and you're done.

Upload the code to the Arduino board. Select your inputs and outputs in the simulator.

Test your code quickly

Whether you are building an Arduino project or just started working with Arduino, you can use this simulator to test your ideas without any electrical or almost no components. We have the most used parts available.

Just add the library and you're good to go

Add the simulator library to your project

In order to let the Simulator understand the code, we changed the libraries to be compatible with ouer simulator. To maintain the usability, we have decided to keep all the instructions as they are, you just have to add the simulator library and you're ready to simulate.
