Muscle music control Using Atmega1284p

Introduction For our ECE 4760 Final Project, we use an infrared LED and phototransistor armband to detect muscle inflections in arm and wrist movement which are used to manipulate the volume and speed of pre recorded songs. By pumping your fist, you will change the speed at which the song is playing.  Isolated wrist movements correspond to volume changes. By moving your hand towards your body in an upward m ...

Audio Spectrum Analyzer Using Atmega644

Our ECE 4760 final project was an audio spectrum analyzer that would display a histogram-style visualization of an audio signal. We were able to successfully display the frequency spectrum content of an audio signal in real-time using a black and white histogram visualization with bins arranged from left to right corresponding to low to high frequency ranges using a system based upon two Atmel Mega1284 micr ...

Optical microphone and spectrum analyzer Using Atmega1284

We implemented an optical microphone which converts distant vibrations, including sound, to an audio signal. Measuring the reflection of a laser beam from windows or glass, it possible to hear sounds near the target. The system also includes frequency spectrum analysis with a real-time display and user-configurable ranges, and it also has an output for headphones to monitor the signal. This may be useful, f ...

Virtuoso: A Touchscreen Music App Using Atmega644

n our final project, we designed an electronic multifunction instrument with a LCD touch screen and a microphone. The user can play three kinds of instruments on it -- xylophone, flute and piano. Each instrument has a different interface and timbre. The piano part has a record/replay function which can echo the song previously played on it. In addition, the system has another function to teach the user to p ...

Wireless, voice-controllable, household system Using Atmega644

Motivation We design a smart home control system which allow people control their home devices by voice command at home. This is a wireless, voice control system. People could control almost all the facilities at home including lights, fans or even back ground music. Right now, the basic function of lights control, fan control and music control have all been implemented. Except for basic turning on and off ...

Auto-composing keyboard Using Atmega644

Project Overview We designed an electric piano that automatically composes a piece of music for the ECE 4760 final project. All the user need to do is to select a mood of the music and play two notes upon which the music is based, and then he can just lie down and enjoy the music created for him. He can also choose to train the piano by first playing several pieces of music he is fond of. The piano would th ...

A Keyboard Synthesizer Workstation using Atmega644

Our Keyboard Synthesizer project aims to create a multi-instrument keyboard that can record several different synthesized instruments and play back the track simultaneously. We took a children’s toy keyboard and adapted the printed circuit board within to play a range of notes from various musical instruments. Our user interface is a phone-style keypad for command input along with an LCD that displays the v ...
