Optical fiber-based bi-directional voice and data communication system
Designed and implemented an optical fiber based communication system using two NI FOTEx modules that can transmit voice and digital data in one direction, while only voice signal in the other direction.

USB-based 16 channel logic analyzer
It can take digital input from physical circuit, send the data to computer and display them as plots. Designed and developed it in PCB. Used USB interfacing by ATMEGA32 micro-controller.

Visualizing interference fringe due to two-point sources
The interference fringe created by superposition of monochromatic light waves originating from two coherent point sources separated by a small distance relative to the distance between the sources and the screen were visualized shown using MATLAB code.

Stepper motor controller
Designed and simulated in Proteus, then implemented in hardware using Micro-controller. Implemented full-step and half-step sequences for rotation and speed controlling.
