Integrating Wiznet W5100, WIZ811MJ network module with Atmel AVR Microcontroller

The rapid penetration of the internet networks into many of today’s modern homes and personal gadgets (e.g. smart phone and smart pads) opening a tremendous useful and interesting embedded system application that could be integrated into our house or known as the intelligent house. For example by putting a small embedded system web server in our house, we could easily monitor such as alarm, temperature or e ...

Power Manager: Remote Power Control Through LAN using Atmega644

Introduction Overview PowerManager is a remote power management system that can be controlled through a web browser on a local area network (LAN). Devices plugged into PowerManager's outlets can be turned on or off with the click of a button on a webpage. PowerManager runs on an ATMEGA644 microcontroller and an ENC28J60 Ethernet controller. Together, this embedded system acts as a web server to serve a web ...

Intelligent wireless pedometer Using Atmega32

Introduction For our ECE 476 Final Project, we have built an intelligent, wearable pedometer. This wireless pedometer can calculate many useful statistics such as the number of steps a user has taken, the distance and the speed the person has walked/run, as well as the number of calories the person has burned. This information is wirelessly transmitted to the base-station, and it is displayed on the PC in a ...

The Ultimate MP3 Radio Using ATMega32

Introduction Perusing through the impressive list of past projects, we decided to make our final project a combination of two technologies—wireless technology and the MP3 player. Specifically, we decided to create an MP3 player that broadcasted the songs to an FM dial. We call this the "MP3 Radio." To accomplish this, we used an ATMEL ATmega32 MCU, a STA013 MP3 decoder, and an IF VCO MAX2606 FM transmitter ...

Wireless Electromyograph using ATmega32

Introduction This project implements a wireless surface electromyograph that displays the signal using a television as an oscilloscope. Electromyography detects the electrical signals that the human body generates to contract muscles. Detecting very low voltages in the milliVolt range on the skin surface is not a trivial task. As shown in figure 1, EMG signals are inherently low frequency signals. The human ...

Laser Communications System Using ATMega32

Introduction Laser communications systems are wireless connections through the atmosphere. They work similarly to fiber optic links, except the beam is transmitted through free space. While the transmitter and receiver must require line-of-sight conditions, they have the benefit of eliminating the need for broadcast rights and buried cables. Laser communications systems can be easily deployed since they are ...

Wireless Keyboard Using Atmega32

Introduction: For our project, we designed a wireless keyboard that uses RF to transmit signals to the computer. In our design, we use a regular, 102 key ps/2 keyboard and connect it to our transmitter circuit. On the computers side, we connect our receiver circuit to the ps/2 port on the back of the computer. With this set up, we convert a cheap ordinary keyboard into a wireless keyboard. [caption id="atta ...
