### Why MATLAB?
MATLAB® is an educational and industrial programming platform used to analyse data, perform simulations and carry out model based designs. Through an interactive communication with an Arduino board, you can expand MATLAB's capabilities, while also gaining access to a wide range of math, engineering and plotting functions. Check out the capabilities of MATLAB® over on the [MathWorks website](https://www.mathworks.com/solutions.html#capabilities). In this tutorial, we will establish the connection with MATLAB via a USB and Wi-Fi connection.

The [MATLAB Support Package for Arduino Hardware](https://www.mathworks.com/matlabcentral/fileexchange/47522-matlab-support-package-for-arduino-hardware) must be installed (which may require a MathWorks account), in order to facilitate the communication between the MATLAB software on your computer and your Arduino board.
### Static vs Dynamic IP Addressing
When you connect your Arduino board, you should see the COM port under Device Manager. By referencing the COM port, you can create a two-way data link between your computer and the Arduino device. For a device connected on a network, we can use an Internet Protocol (IP) address to identify it. In the IPv4 standard, this is written as a series of four numbers such as `192.168.1.100`. By default, most routers are configured to assign a dynamic address via a Dynamic Host Configuration Protocol (DHCP). This means less configuration, but at the cost of the IP address changing. In order to reliably address your Arduino board, you may wish to utilise a static IP address. Once a static IP address is assigned, it will stay the same.

## Control LED over Wi-Fi with MATLAB
**1.** Firstly, make sure your Arduino board is connected via the USB cable. Run `clear a` to remove the previously created arduino object and then run the `arduinoSetup()` script again. This time, select the Wi-Fi option. You will see that a few options appear at the bottom left. Select your Wi-Fi encryption type and enter your SSID, password and port. By default, the Arduino board will obtain a dynamic IP from your router.

If the code is not working, there are some common issues we can troubleshoot:
- Make sure to clear previous Arduino objects linked to the device.
- Make sure to clear previous Arduino objects linked to the device. You can do this by running the command `clear a` where `a` is the Arduino object.
- If you get the message `Unrecognized function or variable 'arduinosetup' ` ensure that you have installed the [MATLAB Support Package for Arduino Hardware](https://www.mathworks.com/matlabcentral/fileexchange/47522-matlab-support-package-for-arduino-hardware).
