ECE 477 Final Presentation Team 01 Spring 2014 Project Summary
In the ECE 477 Final Presentation for Team 01 in Spring 2014, the project involved creating a configurable melody generator with LED pushbutton grid, adjustable volume, and tempo settings. The team members, Kevin Meyer, Ben Pluckebaum, Brennan Tran, and Jonah Ea, worked on different aspects from design challenges to individual contributions. Kevin led the team, focusing on project management and software development, while Ben handled component ordering and prototyping. Brennan contributed to PCB layout and packaging, and Jonah focused on software engineering tasks. The project aimed to enable users to save melodies to memory and export them as MIDI files to an SD card.
