Saikat Patra is passionate about

electronics and MCU-based

embedded system applications

Shibendu Mahata is an M.Tech (gold medallist)

in instrumentation and electronics engineering

from Jadavpur University.

Currently, he is pursuing Ph.D

from NIT, Durgapur. He has keen

interest in MCU-based real-time

embedded signal processing and

process control systems

The procedure to install the ‘Legacy
MATLAB and Simulink Support for
Arduino Package’ is described in
‘Controlling a Robotic Car Through
MATLAB GUI’ DIY article published
in Oct. 2016 issue.

2. After correctly setting up the
   path for the package, open source

code files (ic_tester.m) of this pro-

ject. Keep both the source code files

in the same folder. Edit COM port

(in the line a=arduino (‘COM19’))

with the port number in your PC

where the Arduino Uno board has

been installed. Run the file and

click ‘Connect’ button to establish

connection between MATLAB and

Arduino Uno board. After successful

communication is established, select

proper IC from the drop-down menu

and click ‘Test’ button in the GUI to

test the IC.
