Keypaw Using Atmel Mega32

1 Introduction The Keypaw is a 12-button input device that provides computer users with an ergonomic, fully-configurable alternative to the traditional QWERTY keyboard. The Keypaw is a microcontroller-driven device with 12 buttons mounted on two handsets; 1 button is provided for each finger, and 2 buttons are provided for each thumb. Pressing a button or combination of buttons on the Keypaw produces a sing ...

TV/Keypad Interface for Winamp Using Atmel MEGA32

MP3 is presently a household term; the reader will likely own a few, barring any intervention from the RIAA. Since it's not always practical to sit in front of a monitor and keyboard when you want to listen to music (e.g. in a car, on the couch, in the bathroom), we decided to create a novel user I/O system that interfaces with Nullsoft Winamp and removes the user somewhat from the computer itself. To this ...

Stepper Motor Indexer & Decoder ECE 476 Using ATmega32

1. Introduction For our final project we built an ATmega32 based stepper motor controller which measures the angular position of the motor shaft using an optical encoder and quadrature decoder. Our system performs 3 basic functions: (1) Communicate with a PC by means of a RS-485 interface, and (2) Generates step and direction signals for a US digital MD1 microstep drive, and (3) Monitors the stepper motor r ...

Connect Four with Programmable Infrared Receiver Atmel Mega32

We have designed a programmable infrared receiver which can utilize any pulse coded IR signal to play Connect Four from a remote distance. The programmable infrared receiver device we have created can decode any pulse-width modulated signal of an IR remote control, store it in non-volatile memory, and then recognize that signal again the next time it comes to existence.  We have also coded Connect Four whic ...

Memory Video Game Using Atmel Mega32

Introduction The main goal of this project was to write and develop a graphical version of the card game commonly referred to as Memory for use on an Atmel Mega32 microcontroller unit. Memory is a card game where the player tries to match pairs of identical cards together by only flipping any two cards over at a time. If the two selected cards match, they are removed from the current playing field; otherwis ...

Hard Drive Based AVR Programmer Using Mega163

The project which we are presenting is not the project we presented in our proposal. We initially planned to build a WWVB time-code receiver, which would demodulate a 60 kHz signal and extract an extremely precise time according to the National Institute of Standards and Technology (NIST). Unfortunately, due to a weak signal and noise interference, we decided that a time-code receiver would not be feasible ...
