Arduino Projects For Beginners With Code

Simulink Support Package for Arduino Hardware enables you to create and run Simulink models on Arduino board. The target includes a library of Simulink blocks for configuring and accessing Arduino sensors, actuators and communication interfaces. Additionally, the target enables you to monitor and tune algorithms running on Arduino board from the same Simulink models from which you developed the algorithms.

In this example you will learn how to create and run a simple Simulink model on Arduino board. See other examples for Arduino board to learn how to use External mode and to learn how to implement more complex algorithms.


If you are new to Simulink, we recommend completing Interactive Simulink Tutorial and running Simulink Getting Started example.

Required Hardware

To run this example you will need the following hardware:

  • Supported Arduino board

  • USB cable

  • LED

  • 220 Ohm resistor

  • Breadboard wires

  • Small breadboard (recommended)


Consider this model.

Task 1 - Connect an LED to an Arduino Output Pin

In this task, you will connect an LED to an Arduino output pin so you can see changes in the logical state of the pin.

1. Attach one end of the 220 Ohm resistor to output pin 9 on the Arduino board. Use the recommended breadboard and the breadboard wires.

2. Attach the long leg (positive) of the LED to the resistor. Attach the short leg (negative) to the ground pin on the Arduino board.

Task 2 - Review Arduino Block Library

Tutorial Arduino Uno

Simulink Support Package for Arduino Hardware provides an easy way to create algorithms that use Arduino sensors and actuators by using the blocks that can be added to your Simulink model. The blocks are used to configure the associated sensors and actuators, as well as to read and write data to them.

1. Enter slLibraryBrowser at the MATLAB® prompt. This opens the Simulink Library Browser.

2. In the Simulink Library Browser, navigate to Simulink Support Package for Arduino Hardware > Common.

3. Double-click the Digital Output block. Review the block mask, which contains a description of the block and parameters for configuring the associated Arduino digital output pin.

Task 3 - Create a Model for Arduino Hardware

Tutorial arduino nano

In this task, you will create a simple Simulink model that changes the state of the Arduino digital output pin.

1. In MATLAB, select HOME > New > Simulink Model.

2. Drag the Pulse Generator block from the Simulink Sources library to your model.

3. Double-click the Pulse Generator block. Set the Pulse type to parameter to Sample based and set the Sample time parameter to 0.1 second.

4. Drag the Digital Output block to the model. Use the default block settings.

5. Connect the Pulse Generator block to the Digital Output block.

Task 4 - Configure and Run the Model on Supported Arduino Hardware


In this task, you will configure and run your model on the supported Arduino board.

1. Connect the Arduino board to your computer with a USB cable.

2. In your Simulink model, click Simulation > Model Configuration Parameters to open Configuration Parameters dialog.

3. Select the Hardware Implementation pane and select your required Arduino hardware from the Hardware board parameter list. Do not change any other settings.

4. Click OK.

5. In your Simulink model, click the Deploy to Hardware button on the toolbar. The model will now be deployed to the connected Arduino hardware.

6. Look at the LED attached to pin 9. The LED should blink one time every second.

7. Save your model.

A pre-configured model is included for your convenience.

Other Things to Try

Experiment with other blocks in the Arduino block library. For example:

  • Create and run a model that turns the LED on if a signal is applied to a digital input pin.

  • Create and run a model that repeatedly brightens and dims an LED. Hint: use the PWM block.


This example introduced the workflow for creating an algorithm from a Simulink model and then running it on the supported Arduino board. In this example you learned that:

  • Simulink Support Package for Arduino Hardware provides blocks for configuring, reading from and writing to Arduino sensors and actuators.

  • You can use the Deploy to Hardware button to configure and run the model on supported Arduino board.

The concept of prototyping in electronics was limited to research centers and laboratories with complex equipment, big budgets and technical expertise. But this has changed with the introduction of Arduino, a prototyping programme in electronics. The best part of this Arduino concept is it is open –source i.e. all the information is available for free.


Since its introduction, Arduino took the electronics industry by storm with a wide range of people getting involved in it like electronics hobbyists, students, artists, designers, experts in electronics and even people without any experience in electronics.

We developed a tutorial for Arduino in order to bring this open – source platform to more audience. The aim of this course is to introduce the concept of Arduino and go through the steps and process involved in the development of Arduino based projects by understanding the different hardware and software features of the Arduino environment.
