Introduction We have designed and built a LED t-shirt capable of displaying the heart rate of the wearer via a pulsing LED heart. Largely, our project consists of two components: the plethysmograph and the LED display. How we came up with the Idea We had thought up the idea of a heart rate display led

INTRODUCTION Wouldnt it be cool to be this guy? Powerful laser shining into the audience, playing strings by sweeping your hands across the beams, rocking out in a room full of fog and fawning girls? We thought so. It turns out lasers are expensive, fog machines arent allowed in lab, and fawning girls experience some

Introduction The Weather Canvas is a robust outdoor weather monitoring system coupled with an indoor LED display. The outdoor system consists of a microcontroller, temperature sensor, humidity sensor, home-made anemometer, a Hot Wheels radar gun modified to measure precipitation, and a solar panel to measure sunlight and charge the microcontrollers power source. Once per minute,

Introduction For our final project, we built a mechanism that spun a linear array of seven LEDs at a velocity that made it appear as if a message was being displayed using persistence of vision for the human eye. To accomplish this, we first had to design and build the hardware components, which may have

Introduction With the increasing awareness of sustainable and green building, more and more people are concerned with the efficiency of energy use at home and at work. For our ECE 476 Final Project, we developed a microcontroller-based, interior illumination system – The Heliostat Skylight. By reflecting light that would otherwise be lost, the Heliostat Skylight

Introduction Our project, in one sentence, is an orientation independent 3D LED display. We were inspired by various videos on youtube of similar cubes but also by the idea of creating an interactive 3-dimensional display. We built a 5x5x5 LED cube display and controller board which interfaced the cube to a Mega32 microcontroller. We can
