Introduction For our ECE 4760 final project, we designed and built an array of 12 independently-controllable speakers to implement an acoustic phased-array system. The system samples a standard audio input signal at approximately 44.1 kHz, and then outputs this signal to each of 12 speakers, each with a variable delay. The idea behind a phased-array […]
Introduction One of the more challenging aspects of owning a home entertainment system is dealing with all the remote controls. My device is designed to tackle this problem. Specifically, the universal remote control I implemented is able to learn the signals used by other remote controls, store those signals in its own memory, and send
Introduction We implemented a prototype for a moving alarm clock which runs away from the user when they try to silence the alarm. It has all the features of a “regular” alarm clock: settable time and alarm, snooze, and alarm on/off. The alarm clock displays the time in 24-hour format on a LED seven-segment display.
Introduction Most homes across the world lack a security system of any sort. The goal of our project was to design a simple security system using the Atmel AVR ATmega1284p microcontroller that most people could build without too much hassle for an affordable price. This project uses a few external peripherals to accomplish this goal;
Introduction Several different approaches have been explored in developing a system to track eye movements. These approaches span from measuring reflections of infrared light to using advanced imaging techniques to monitor specific features within the eye. While a variety of reports exist on measuring infrared reflections off of the eye, the long term effects of
Introduction We designed and built a glove to be worn on the right hand that uses a Machine Learning (ML) algorithm to translate sign language into spoken English. Every person’s hand is a unique size and shape, and we aimed to create a device that could provide reliable translations regardless of those differences. Our device
Introduction The objective of this project was to create a two-wheeled balance bot able to traverse a flat environment and adjust itself to shifts in position and weight, using a Proportional-Integral-Derivative (PID) feedback control loop to keep the robot upright. The balance bot is essentially a wirelessly controlled segway that leans its body forward and
Our project aims to take the fun of a Wii Remote and translate it to real life. The AccelCar is a remote-controlled car that is controlled by the way that a user tilts the remote, similar to the way Mario Kart Wii is played. The angle of the tilting determines the speed and direction in
Our ECE 4760 final project is to build a microcontroller based smart medicine box. Our medicine box is targeted on users who regularly take drugs or vitamin supplements， or nurses who take care of the older or patients. Our medicine box is programmable that allows nurses or users to specify the pill quantity and day
Introduction For our final project in ECE 4760: Digital Systems Design Using Microcontrollers, we designed and implemented a radio-controlled, map-learning, line-following robot. The robot traverses a map of lines with a configuration that is initially unknown to a user. The robot discovers different types of intersections in the map and reports them to a base
