The reason for making this project is that I was always fascinated by Conways Game of Life. It’s a great demonstration of the fact that simple things with a very simple set of rules can do wonderful things: spawn more of them, modify themselves, do logical operations, even create Turing machines. I suspect much more can be …

This hack shows how to make a dumb terminal out of a keyboard, LCD screen, and an 8-bit microcontroller. From time to time, a portable dumb terminal can be handy for when you have to rescue a headless server that’s acting up or if you are building a minicomputer out of a WRT, or if …

The Network Time Protocol (NTP) has revolutionized the world. Suddenly one could have anywhere in the world accurate time and date. NTP is a simple UDP based protocol and can be implemented in a Microcontroller. Using the tuxgraphics ethernet board and a LCD display we build a nice clock which gets time and date via …
LCDs are often used in microcontroller projects. Most used are these green character displays with two or more rows to display menus, status or debug messages. With mass production of mobile phones, color LCDs get that cheap, that they can be used as replacement. Some time ago I ordered a Nokia 6100 LCD including breakout board from …
I spent part of an afternoon developing a hardware RSS reader (most of my time was spent on the python side of things). It’s pretty simple and uses an AVR microcontroller connected to a computer via a serial cable. Hardware I am using the Dragon Rider 500 as a development board. This provides all of the hardware …
Well this is not different from the way interfacing the LCD to 8051 or PIC microcontroller. The crystal oscillator will provide the clock to the microcontroller. The capacitors connected to the crystal will act as filters and help the crystal to resonate and oscillates to its parallel resonate mode. The potentiometer which is connected to …

Interfacing LCD Display in 8bit Mode I’ve already discussed about the LCD display in a note here in this website. You can read the Note on character LCD Display here. Now let us come to the interfacing side of LCD. Let us see the 8bit mode interfacing of the LCD display with an AVR micro controller first. …
Recently I was working on a project that involved rotary encoder. I thought I’d share some thoughts on how rotary encoder can be interfaced and programmed. Actually it is easy to work with rotary encoders – interfacing is simple – only three wires are required to connect to microcontroller (two for signal (quadrature outputs) and one for …
In this project i have interfaced an GPS with AVR microcontroller, the ATtiny2313 gets the location from the GPS and display it over the LCD display. This project also have the feature of marking a place with its name. For entering the Name of the place i have used the PC-AT Keyboard. At starting the microcontroller will display the latitude and longitude on the LCD display …

Here’s my instructable for a DIY TiX clock. It is powered by an AVR microcontroller. The display is made up using a piece of reflector grid you find covering office lights, some smoked perspex, a diffuser and a bunch of LED’s. The Idea came from the Tix clocks you can buy at various places on the web, …
