AVR Microcontroller Tutorials & Projects

AVR microcontroller projects: Learn to work with AVR microcontroller and interface various peripheral devices. This section of EG Labs has interesting microcontroller projects based on AVR microcontroller. These AVR projects can serve as a good reference for final year electronics engineering projects and hobby purposes.

In today’s secure world biometric safety is on the top. Unlike other techniques which make use of passwords and numbers, that are needed to be remembered, biometric techniques make use of human body parts like fingerprints or even iris of your eyes and as we know that these things are unique to all thus it makes biometric systems the most effective over others. In this project I have interfaced a very popular fingerprint scanner R305 with AtMega 16 microcontroller. This module communicates over UART protocol with microcontroller i.e. it makes use of Rx and Tx pin of microcontroller to interact with it.

This tutorial explains how to make your own power supply unit for all your electronics and embedded system experiments. It also has a backup battery which will be used in case of power cuts and a display.


Have you ever wondered of operating a toy car with you own mobile phone? Yes I have made such a thing. This project involves the communication between your mobile phone and the car. Here I have used the internal accelerometers of the mobile phone to operate my toy car.

The system communicates wirelessly over Bluetooth interface, thus we require a phone with Bluetooth compatibility. Moreover I have made an Android Application for the same task therefore the phone must have ANDROID operating system J
