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 […]
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
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

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.

Part 1: Introduction 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!

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

This article describes the design of a Text on TV project. It takes serial data and displays text on a TV screen. The hardware part of this project is pretty simple. It uses an Atmega8 microcontroller that runs with a 16 MHz crystal. The article provides the details on PAL and NTSC timing signals, as

This project describes an open source color game development platform based on an AVR microcontroller. You can code a color, high resolution, smooth video game, like Super Mario Bros or Commander Keen on this system. All video processing is done by software in background using interrupts, with no external active components. You only need to

This project is from Extreme Electronics that describes an AVR-based (Atmega8) remotely controlled fan regulator. The control commands are received through a DVD player remote control. With three buttons on the remote control, you can turn the fan On and Off and also conotrol the speed. You can also purchase the PCB for this project
