How to choose a MicroController

It used to be that the number of different microcontroller chips available to the hobbyist was pretty limited. You got to use whatever you could manage to buy from the mail-order chip dealer, and that narrowed down the choice to a small number of chips. But times have changed. Digikey lists over 16000 different line items under a 'microcontroller' search. Which one should a hobbyist with no particular prior ...

How to get started with Eclipse and AVR

Programming AVRs is fun, but sometimes the manufacturers development environments make code maintenance a chore. If your looking for a free, cross platform, high quality piece of software for programming AVRs Eclipseis a good choice.Moving to an Integrated Development Environment (IDE), such as Eclipse is a logical step up from learning to program basic functions. By using an IDE you will be able to work ea ...

An Absolute Beginner’s Guide to 8-Bit AVR Programming-AVR Dragon

If you'd like to test the waters of microcontroller programming, the new AVR Dragon by Atmel Corporation is a nifty, low-cost entry-level development tool. Unfortunately, right out of the box, the AVR Dragon is not the definitive answer for the beginner looking for an all-in-one solution. Rather, the AVR Dragon is a great microcontroller programmer foundation, but it is seriously lacking in enabling the beg ...

Relais Board Using AT2313

Description This is a peripheral board with 4 relais, rated at 5A/250V each. The board has a ML10 output connector for connection with the AT2313 Project board. It has also 4 LED's for indication which relais is switched on. Hardware The circuit is simple, it consists of no more then an ML10 connector, a ULN2803A, which contains eight open collector darlington transistors, four of them amplifies the signals ...
