Project description:
We decided we wanted to build a Tetris-like game for our final 476 project. We felt this project would challenge our hardware and software skills. We liked the numerous optional features that we could add but were not crucial. For copyright reasons, we decided to change the rules and the pieces from the classic […]

In the vein of today’s trends to embed networking cababilities into simple appliances, our project implements a webpage interface for the Atmel AVR microcontroller. One of the original motivations of this project was to develop a low-level network interface for the Atmel device, specifically by controlling an ISA network card (see the eAVR Project) […]

Project description:
My goal was to create a sequencer that is basic, yet has enough functionality to be useful, and not just an academic exercise. Because of hardware contstraints, I decided to build something that was more of a “sketchpad” for musical ideas with several basic […]

Project description:
We aim at building an autonomous vehicle, “Homer”, which can stroll around an environment (e.g. our lab, or an environment that we build) without getting stuck at obstacles. That implies that we need a robust algorithm that tells the vehicle how to steer when it gets into different obstacle situations.   The goal would be […]

Project description:
The original motivation behind our project was a desire to interface with some type of real world device. Since one of the clear limitations of the Atmel chipset is the lack of storage space, we felt it would be useful if we could connect to some type of mass media storage device. Implementing a […]

Project description:
Our security system is a stand alone device that allows access to registered users identified by their magnetic cards.(For this project, “access” is represented by a lit LED, showing how the system could be used to control an external locking mechanism.)

Project description:
For my final design project I decided to design and build a digital dot matrix message device. I’ve seen devices similar to this before and I wanted to find out if I could build one myself. The display consists of 7 LEDs in a vertical row. By moving them fast enough back and forth […]

Project description:
We thought it would be interesting to try and construct a simple modem out of the ATMEL 8535. The main motivation for doing this was to test some DSP theories about the effects of transmission power, noise, and modulation technique on the bit error rate. Initially, we wanted to connect our modem to the […]

Project description:
We used an Atmel AT90S8535 microcontroller for this project. We used the ADC on the chip to read the positions of the potentiometer controllers (see Hardware). The game is for two player simultaneous play, although we found it is also challenging and fun to play against yourself using both controllers.

Project description:
For our final project, we decided to enhance the controls of a Hummer RC truck. Our main objective was to demonstrate that an Atmel microcontroller together with basic hardware building blocks can replace all of the car’s original circuitry. Improving the RC truck’s handling involved adding analog control over steering and speed. The original […]

Project description:
Our alarm clock features a large, bright time display, easily visible in the bedroom. It also features a loud, irritating alarm, sure to wake even the soundest of sleepers. By far the most innovative part of the alarm is the LCD display, which gives the date, alarm status, and status for setting the clock.

Project description:
Our final project involved the design of a fully functional, multi-purpose digital thermometer. This was our attempt at producing a portable device that could be widely used for a variety of different purposes. For example, think of the many situations where the precise measurement of temperature is of high importance. Temperature control and monitoring […]

Project description:
This is my second MP3 player build around the MP3 decoding chip from ST. This perticular design is aim for a portable system. However, the D/A chip used require 5V power supply, so a dual voltage inverter is required to boost the voltage from 2 AA cell to both 3.3V and 5V. The power […]
