Summary of Control Arduino Wirelessly with MATLAB

This article demonstrates a simple project to control an Arduino wirelessly via MATLAB using an ENC28J60 Ethernet shield. The Arduino, connected to a router through the Ethernet shield, communicates with MATLAB running on a PC. An LED connected to the Arduino indicates successful wireless communication. The setup involves configuring the Ethernet shield, ensuring correct IP settings within the router's DHCP range, and uploading the appropriate Arduino code. This approach enables wireless control without physical USB connections once the system is set up.

Parts used in the Control Arduino Wirelessly with MATLAB project:

Arduino (or Gizduino controller)
ENC28J60 Ethernet Shield
Wi-Fi Router
LED
Printer Cable (USB cable for Arduino-PC connection)
UTP Cable (Ethernet cable)

Been seeing few DIYs on how to establish a communication between MATLAB application and Arduino that is hardwired to PC. However, I haven’t encountered anything that control Arduino via MATLAB wirelessly using the ENC28J60 compatible Ethernet shield. In this ible’, I’m going to show the simplest way to control Arduino using MATLAB wirelessly.

WHAT YOU NEED?

1) Arduino – You need a controller. I used Arduino since it is supported by MATLAB. For this project however I used, Gizduino, a locally made Arduino-based controller.

2) Ethernet Shield – You need a compatible Ethernet shield for your board. I used the ENC28J60 for my board.

3) Wi-Fi Router – To connect your Arduino which would be the means to communicate to your PC wirelessly.

4) LED – Any components to indicate communication between devices. For this project I used LED.

5) Printer Cable – To connect Arduino to your PC.

6) UTP Cable – To connect your Ethernet shield to the router.

Step 1: Connect Ethernet Shield to Arduino

Carefully connect your Ethernet shield to your Arduino. Avoid bending the pins.

Step 2: Connect LED

Connect any components that could indicate communication between devices. In this ‘ible I used an LED. Will try to turn LED on and off wirelessly using MATLAB. I’ve connected my LED’s anode (long pin) to Digital I/O pin 6 of the Ethernet shield attached to the Arduino and LED’s cathode (short pin) to Ethernet’s GND.

Step 3: Connect Arduino to PC

Plug-in the printer cable to your Arduino and connect to PC.

Step 4: Connect Ethernet Shield to Router

Plug-in UTP to your Ethernet shield and any of the LAN ports of your router.

Step 5: Open Arduino IDE

I used Arduino 1.0 because of the Ethernet shield library compatibility. After opening Arduino 1.0, download the library and copy paste the content to the library folder of your Arduino 1.0.

Step 6: Upload Code to Arduino

Before uploading the codes to your Arduino, make sure of that you have indicated a web server address that is with in the DHCP server range. To learn the DHCP server range of your router, you may access your router by opening a browser and typing the default gateway address, 192.168.0.1. Most of the router uses this default gateway address, however, some router may use different address. To learn the address of your router you may access the command prompt, if you are a Windows user, type in ipconfig and hit on enter. Look for the default gateway address if you are connected to your router.
