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 […]

Our project implements a touchpad input system which takes user input and converts it to a printed character. Currently, the device only recognizes the 26 letters of the alphabet, but our training system could be easily generalized to include any figure of completely arbitrary shape, including alphanumerics, punctuation, and other symbols. A stylus is used

Introduction Point of Sale systems typically can cost up to thousands of dollars we do it very simply for seventy. For small stores, point of sale systems can be very expensive. One thousand dollars for a piece of machinery whose functionality is quintessentially simple can be exuberant. Our goal was to design a point of

Introduction This project implements a 2D matrix of bidirectional LEDs to simulate how fireflies in a population synchronize their flashing. Fireflies are an extraordinary species of bioluminescent animals which are able to synchronize the timing of their light emission within a flashing population. In places such as Thailand and Malaysia, during night at the right

Introduction For the Final Project in ECE 476: Designing with Microcontrollers, Robbins and Saha developed a Speech Recognition Jukebox, comprised of a speech recognition system that activated a simple music player. The speech recognition system was capable of recognizing four commands and could cycle through a simple play list of three songs. The jukebox could

Introduction: MIDI Synthesizer Our Final Project for ECE 476 was building a MIDI synthesizer using a MEGA 32 microcontroller. At first we wanted to tear apart an old keyboard and use the MCU to decode directly from the sensors which detected key presses. We then learned about the MIDI protocol and decided to use the
