Electric Etch Using Atmega644

Introduction The "Electric Etch" project takes the classic Etch-a-Sketch® toy and turns it into a non-volatile, continuous-line display capable of drawing the current time and text messages. On the classic Etch-a-Sketch, it is notably difficult to draw shapes by hand that involve elements any more complex than simple horizontal and vertical lines. That's why we decided to motorize this toy and apply our kno ...

Tic Tac Toe with CMOS Camera Using Atmega32

Introduction Using computer vision and rules for a perfect tic tac toe game, we have built a system that would never lose in a fair game (i.e. marking 1 cell per turn) of tic tac toe. The idea is simple, have a camera driven Mega644 system that detects for changes on a Tic Tac Toe board, figure out the next move, and not lose a single game ever! The motivation for this project is to test the computer vision ...

Multi-Player Light Cycle on Color TV Using Atmega32

Introduction: Our project is a two player tilt controlled video game based on the classic Light Cycle arcade game. The purpose of the game is to guide your player through the arena avoiding the boundaries and trails created by you and your opponent. Whichever player causes his or her opponent to crash is victorious. Our project was divided into three portions: the actual game software, the tilt controllers, ...

uControl DVD macro-controller Using Atmega32

Introduction This project creates a programmable device that can control a DVD player on scheduled times by sending infrared signals. The uControl allows the user to control their DVD player as if they are using a remote control. However, unlike remote controls, uControl allows the user to program a sequence of button pushes that will automatically run at a time that they can set. To schedule the sequence o ...

CCD imager Using Atmel Mega32

Introduction The CCDImager is an Atmel Mega32 microcontroller driven imaging system that uses a Charge-Coupled Device (CCD) optical sensor to capture a still image. The purpose of this project was to design a basic imaging device from first principles. While brainstorming for ideas for the final project, we came across several varied applications of microcontrollers, from music synthesis and processing to w ...

High-Resolution Color Television Using Atmel Mega32

Introduction: Our project is a serial port-controlled, high resolution color television picture display. We divided the project into the image transfer and storage portion and the television display portion. We opted for an RS-232 port for picture transmission because it involves a relatively simple, well-known protocol that will allow us to change the picture on a whim, rather than hard-coding an image int ...

High-Resolution Color TV Using Two Microcontrollers Atmega128, AtMega32

Introduction My final project creates a relatively high resolution color TV display by using two microcontrollers with shared access to external memory. In the fall of 2005, I worked on a microcontroller project to create color video using an Atmel microcontroller. I had soon realized that since the microcontrollers have a very small amount of SRAM in them (even the mega128 only has 4kB), the resolution tha ...
