Fish: Video Controller

Introduction: The basis of this project is to create the game fish on the Atmel board. In the game fish, the big fish eat the small fish, so your job is to eat the fish smaller than you while not getting eaten by those bigger than you. You �eat� a fish by moving close enough to touch the fish, and if a larger fish gets close enough to touch you, you will be eaten. Furthermore, much like your mother told you ...

The Zip Drive

Introduction 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 SCSI interface would allow us to connect to virtually any type of storage device - hard drives, CD-R ...

Blackjack

Introduction In this project we created a video blackjack machine using AT90S8535. In our previous labs we have gained familiarity with the 8-bit AVR microcontroller and the UART interface to transmit to and receive from a terminal. Our blackjack machine outputs text to the terminal through the UART, and at the same time accepts input from the user through push buttons. The core of our program is a random n ...

Video Overlay using ATmega8 microcontroller

A few years ago I set about trying to design a very cheap and simple way to superimpose flight data on live video being transmitted over amateur television. Specifically, the data would include things like Latitude, Longitute, and Altitude, among other text including an identifier like my callsign. Before I go on, I want to point out two other designs I really like. The first I found when researching how ot ...

Nikon Camera Remote Control using ATtiny13 Microcontroller

This is an IR remote control for Nikon cameras. It is compatible with the Nikon ML-L3 remote control. Supported cameras include: D40, D40X, D50, D60, D70, D70s, D80, Coolpix 8400 8800. This design is based on an idea from http://www.bigmike.it/ircontrol/. The circuit is extremely simple: an ATtiny13V, button, transistor, resistor, IR diode and 3V battery. You could even omit the transistor and resistor, and ...

Arduino VGA via Interrupts using AVR Microcontroller

Part 1: Introductio For some people, interrupts are a mystical thing that they think they will never understand. To that I say non-sense! And to that effect and to help us also better understand VGA, let's see if we can't output some basic VGA signals like we've done before, but this time using some interrupts! In this article we'll explore how to output VGA signals from an Arduino UNO by using the timer in ...

VGA Monitor adaptor using AVR microcontroller

Background of the project.   Several months ago I tried to connect a microcontroller system to a VGA monitor to output data in the form of text. I was surprised to find little on this subject on the internet, to assist me in achieving this goal. Certainly nothing simple a beginner could find useful.   There are examples out there that utilise standards such as PC-104 or complex FGPA implementation ...
