Arduino Simulator Drag & Draw


Let me introduce a brand new Arduino Simulator!


The Arduino Simulator has been drastically changed the way you use a simulator. By communicating with the Arduino board we can simulate the IO on your screen. It's designed to optimally simulate your (IO) projects with a graphic aspect on top.

We provided enough components so you can simulate your project or replace the missing parts with software ones. To make everything as easy as possible we created a library that allows users to simulate there project with just adding that library.

Arduino Simulator Drag & Draw - The Arduino Simulator simulates the IO of a Arduino board. | Product Hunt Embed


Arduino Simulator course


Register for 50% off, now $25 and get access to 20 projects with videos in which everything is explained step by step. The course contains all the information you need to be able to start yourself afterwards in simulating your Arduino projects.



The Arduino Simulator has many well-known components built in that you can use for your simulations.

Just drag the parts to the worksheet and you're done.


  • 14 LEDs (4 colors or relay, customizable)
  • 8 pushbuttons
  • Squarewave generator
  • Buzzer (Frequency adjustable)
  • Noise detection (microphone)
  • 3 sliders (analog)
  • 7-segment display
  • 6 analog meters (A0-A5)
  • 6 analog meters (PWM signals)
  • 2 relays
  • RGB Led with RGB sliders)
  • LCD display (16-2)
  • Hall effect sensor
  • IR Remote Control


  • 2 Bargraphs
  • Tone melody
  • Sound generator (frequency adjustable)
  • 2 servo motors
  • 2 motors (left & right turning with PWM)
  • 1 Barrier (servo)
  • A DHT11 temperature sensor (temperature & humidity)
  • PIR motion detector
  • Motion detector (motion detection on webcam)
  • Number keypad 16 digits (4x4)
  • Stepper Motor 28 BYJ48
  • Email notification logger

How does it work?








Drag & Drop

Drag the parts in place with our drag & drop system

The border of the component will turn red, this means that you can drag it into the drawing sheet. The top side and sometimes the component itself is used to reduce the component, this causes the settings to disappear so you get more space to use. 

Drawing tools

Draw and create your own simulation in a more realistic way

The simulator has got a big redesign and we added drawing tools as well. You can choose between various types of arrows, circles, rectangles, squares… in every color you want.


There is also a possibility to place texts in different fonts of your choice to make realistic simulations.

Save and restore settings

Save your work for later, restore it at any time

After testing your project it's possible to save your simulation with one click and use it back whenever you want.

The simulator can also be used as a drawing program. Just save the drawing with the save button. 

Connect with serial or TCP

Simulate through serial or TCP

It is possible with the TCP server/client communication to simulate the IO with a ethernet shield or through WiFi connection. There are some thernet/Wifi boards that work with the simulator. You can use a Geekcreit W5100 wifi shield or the Arduino UNO Wifi rev2.

TCP simulation has the advantage that if the port forwarding is set correctly in the router you can operate the simulation from anywhere through the public IP address. Everything is explained in the user manual and support page.

Arduino Simulator Drag & Draw

Simulate your projects

Simulate the IO on your screen

Write your project in the Arduino IDE. Add the Simulator library and change the codes.

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

Use your creativity to make a realistic simulation of your project without having to connect the IO on the board.

It's also possible to connect real IO and combine them with virtual IO.

This Simulator is built

for beginners and creators

Test your code whenever you want

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 and we are still developing new parts.

Get free updates

We have an updater built in to provide you with the latest updates quickly and easily so that you can test your projects even better. If you would like to see a part in the simulator, you can ask us, we will investigate whether it is technically possible to add the new feature.

Plug & Play

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.

Arduino IO Simulator Drag, Drop & Draw

Arduino Simulator Drag & Draw

   The simulator gives you numerous benefits:


  • Get the ability to build your projects out anywhere at anytime
  • Unlocking the full true potential of your Arduino board
  • A live interface for you to interact with your Arduino
  • It takes less money and time spent building your projects
  • Simulate projects through serial or WiFi TCP connection
  • Get a new approach to project planning

You can also combine simulated inputs/outputs from the pc and real Arduino IO, now you have made a little HMI (Human Machine Interface). 



The Simulator has a lot of components that are available to test your projects, we have even been able to integrate more parts into this simulator than ever before. If you want a specific sensor then we can build this for you in our simulator. 

You bought an Arduino, What now?



This Arduino Simulator is different from 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.


You can drag and drop the components in a worksheet and you can draw everything you want around it. It is also possible to load a background into the worksheet.



Minimum requirements:

— 4GB's of memory (RAM)

— Intel Core i3 or AMD E1-6010 APU with AMD Radeon Graphics or  Intel Atom

— Windows XP

Java JDK information

JavaFX will be removed from the Java JDK (Java Developers Kit) as of JDK 11, which is due in September 2018. It is bundled in the current JDK 9 and will remain in JDK 10, due this spring. Commercial support for JavaFX in JDK 8 will continue through at least 2022. Featuring a set of packages for graphics and media, JavaFX has been part of the JDK download since 2012.

We are currently developing our application with the Java JDK software. We use JDK 8 and because Oracle will stop publishing free JDK updates, we will be able to develop our application up to JDK 10. newer JDK versions will not be used to develop our applications.
