NES EMULATION USING ATMEGA32

OVERALL DESIGN GOAL The overall goal of our project was to recreate the Nintendo Entertainment System (NES) using Atmel Microcontrollers.  We decided early on the adding audio to the mix was likely going to be too much work in the time that we had to complete the project.  Therefore, we decided to leave all audio aspects out of the mix.  Therefore, our focus became emulation of the modified MOS6502 processo ...

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 a receiver, which converts the signal back into audio. The receiver can ...

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 output to the ADC that is part of the Atmega644 mi ...

Musical Blocks Using Atmel ATmega 644

ntroduction The purpose of this project is to create musical blocks that output music without requiring some sort of musical talent. Musical Blocks tracks the position of the blocks on a flat surface in a range seen by the Wiimote. The path of the blocks is then converted into a sequence of notes which is output. One can create an interactive system by having many blocks which can be used by many people sim ...

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 being output to earphones, allowing f ...

Rhythm Ring: Interactive Rhythm Sequencer Using Atmega32

I. Introduction The Rhythm Ring interactive rhythm sequencer is an engaging musical device that enables the user to create a plethora of rhythms and beat patterns with the touch of their own fingers. Besides being fun to play with, the Rhythm Ring provides a tangible method of arranging a musical rhythm. In our design, the user can arrange beats and modify them in real time by moving steel ball bearings bet ...
