Low-Cost Portable Potentiostat for Biosensing Applications Using Atmega644

Introduction This project involves the design and construction of a low-cost portable potentiostat capable of performing cyclic voltammetry on three-electrode electrochemical systems. A potentiostat is an instrument used in chemical and biological tests that controls the voltage between two electrodes, working and reference, at a constant value. Chemical and biological tests are typically run in

Optical eye tracking Using Atmega644

Introduction We have endeavored to develop a means by which eye gaze can be detected. This goal was achieved using the same principles learned in Lab4, where we recorded the motor speed of a small hub fan using the combination of IR emitter plus phototransistor, henceforth referred to as an emitter-phototransistor pair. High Level DesignSeveral

Laser Audio Transmitter Using Atmega32

Introduction This project is a proof-of-concept device that transmits an audio signal using a laser beam, while removing the need for the user to align the beam themselves. For our project, we created a mono-axial transmitter/receiver setup that converts an analog audio signal, via a standard 3.5mm jack, and transmits it via a laser to
