Wireless Music Player Using Atmega32

Our wireless music player allows the user to listen to uncompressed digital audio streamed over a wireless link. The music player reads uncompressed audio data from an SD card in an immobile "base station." A pair of Xbee transceiver modules are used to stream data and control signals between the base station and a portable module. The battery powered portable module can be connected to speakers at any loca ...

Radio Frequency Beacon Finder Using Atmel Mega32

This project is a radio frequency receiver that will help the user the trace the direction and distance of transmitter beacon(s) operating at 433MHz frequency. In this ECE 476 final project, we have built a radio frequency receiver unit with an LCD screen that will display information about the RF signals that it is picking up in the vicinity: beacon ID, packet loss from a particular beacon, and the overall ...

Implementation of a (31, 16) BCH code on a Microcontroller Using Atmega32

Introduction: Error correcting codes are used throughout digital communication systems today. Cell-phones, CD players, satellites, digital pagers and many other communication devices all use varying amounts of error control to achieve a certain degree of accuracy in transmitting information. The idea behind error control codes is very simple; one can insert some amount of controlled redundancy into an infor ...

Connect Four with Programmable Infrared Receiver Atmel Mega32

We have designed a programmable infrared receiver which can utilize any pulse coded IR signal to play Connect Four from a remote distance. The programmable infrared receiver device we have created can decode any pulse-width modulated signal of an IR remote control, store it in non-volatile memory, and then recognize that signal again the next time it comes to existence.  We have also coded Connect Four whic ...

Autonomous Vehicle

INTRODUCTION As technology develops, computers are making people's lives progressively easier and safer. Someday they will be able to drive automobiles, resulting in reduced deaths and accidents. We decided to make a prototype of a self controlled car. We started with a Hot Shot II radio control car and stripped out the radio receiver. Then we gained complete control over the drive and steering servos, allo ...

Enhancing An FM Transmitter’s Firmware using ATmega48

This hack is about rewriting the firmware of PLL FM transmitters based on AVR microcontrollers to add more functionalities. They're commonly available on eBay from various sellers and for prices ranging from $40 to $80, depending mostly on the RF output power. If you don't know if a similar transmitter is based on an AVR or not, don't hesitate to ask the seller for a (good) picture of the PCB. They'll certa ...
