In this project we built a sketchpad based on LED matrix display with microcontroller and resistive touch screen control. We used a single point resistive touch screen to detect the user’s gesture and microcontroller’s analog/digital converter (ADC) ports collects the data and convert it to coordinates. We designed a LED drive circuit with shift registers […]
Introduction What is seeing without feeling? The field of Virtual Reality has recently been gaining much attention, with the Oculus Rift and Google Cardboard paving the path of visualizing a world that is not physically there. But what if the virtual reality experience could be enhanced by incorporating tactile sensing? The Haptic Glove we developed

INTRODUCTION In the modern American classic, Rocky IV, Ivan Drago (portrayed by Dolph Lundgren) is shown utilizing a then-futuristic electronic punch meter (in addition to anabolic steroids) in his quest to triumph over Rocky in one of the Cold War’s only face to face confrontations. While we dispensed with the communist symbolism (and controlled substances)
ukule-LED is a ukulele with LEDs embedded in its fretboard. These LEDs can light up in configurations corresponding to different chords, which can aid the ukulele player in learning how to play certain chords, or can act as a chord reference for a more advanced player. ukule-LED has two modes of operations. First, in “play”
Introduction This project visually displays the frequency content of an audio signal using an 8X3 grid of LEDs. A microphone and amplifier collect analog audio input which is sampled digitized using the MCU’s analog-digital converter. The samples are buffered and and a 32 point discrete cosine transform is performed in real time to obtain 32

Introduction The Skittles Mini-Factory is self-contained repackaging unit that separates Skittles by color. Once separated, the Skittles are resealed in individual plastic bags. The Skittles are dispensed one at a time (either automatically or manually) onto a light sensing module. Red, green, blue, and white light are reflected off the skittle and read by

1.1 Introduction Line following car is a system that traces black lines on white surfaces. There arevarious sensing methods available to sense these lines. The choice of these schemesdepends upon sensing accuracy and required flexibility. In my project, I have used 6 TxLEDs and 6 IR sensors to accurately calculate the position of the robot

This past summer I had the opportunity to work for computer science PhD candidate Ryo Suzuki under the guidance of Tom Yeh of the computer science department. My task was developing printed circuit boards for experiments for human computer interaction (HCI). The goal was to create a surface which a magnet could be moved to create

Welcome to my version of the LED reactive table! I was inspired by previous work using discrete LEDs, such as this one, but I figured it would be easier and more fun to use NeoPixels — programmable RGB LEDs that can be set to any color you want. The table consists of a large array of infrared emitters
