Introduction Our project utilizes an array of LEDs that work as light sensors to generate a musical tone, simulating a piano keyboard. The basic idea is to use LEDs as both emitters and sensors. For our project specifically, we used a total of 63 LEDs, 9 for each of the seven natural keys. Only the […]

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

Project overview This small PCB, which I named Multiuse tiny1 was originally designed to convert NES/SNES controllers to USB. Since there is not a lot of space availabe inside an SNES controller, I designed the PCB to be as small as necessary. The PCB has improved since the beginning, thanks to the many other uses
