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

Voice Tuner and its Effects Using Atmega644

Introduction Sound Bite Our project implements a tuner that continuously outputs the frequency of an input microphone signal with a high degree of accuracy. Project Summary This project’s goal is to use a sensitive microphone, computer speakers and a properly designed circuit so that for an input microphone signal a relatively noiseless sinusoidal signal is

Programmable Synthesized Guitar Using Atmega644

Introduction Our project recreates the experience of playing an acoustic guitar electrically using vibration sensors, push buttons and the Karplus-Strong algorithm. Our basic idea is to model an acoustic guitar as closely as possible and then implement additional functions not available to the conventional guitar. This includes allowing the play of the guitar with sound

Dueling Banjos Using Atmega32

Introduction Our project was to create two individual microcontrollers that can play banjo notes cooperatively to play two-part songs using nothing but sound to communicate and synchronize. Humans have had the ability to synchronize musical instruments together to achieve a single, coordinated multi-part song for thousands of years. In our project we attempted to simulate
