GSM Based Intruder Alerting System

Did you know that most of the thefts at home happen when it is empty? But not everyone is rich enough to hire a security for their house and at the same time they themselves cannot be at home 24x7. Now what if there is a system which alerts you about an intruder through a text message? The following tutorial discusses how to make you own intruder alerting system. Components Required 1.     PIR Sensor 2.     ...

GSM Based AC Appliance Control

This project would show you how to control an AC appliance remotely from anywhere using your mobile phone. This kind of project is useful in various applications. Say for example a farmer can switch ON or OFF the motor pump present near his field remotely. In this way he need not travel all the way to the field to control it, especially at night times. Components Required 1.     ATMega16 Development board 2 ...

Digital Saxophone Using Atmega644

Abstract My final project was the design of a digital saxophone which can reproduce the sound of an actual saxophone through digitally synthesized electrical waveforms. The digital saxophone consists of a microphone to sense the user blowing into a mouthpiece, push-buttons to control the note to be played, and the Atmel644 Micro-Controller which processes the inputs and produces the digital output that soun ...

Virtual Saxophone Using Atmega644

Our ECE 4760 final project was to create a virtual saxophone that uses Direct Digitial Synthesis (DDS) to synthesize the output notes. Pushbuttons are connected to a PVC pipe to mimic the saxophone's mechanical structure, and a microphone that detects noise is used to determine whether or not the user is blowing into the device. We decided to do this project because we enjoyed the ECE 4760 Lab on DDS and wa ...

Dual-Channel Mobile Surface Electromyograph Using Atmega644

Introduction For our final project, we built a surface electromyograph to collect and analyze data on muscle activity, which supports two channels, implements wireless transmission, and can be worn as mobile unit. Surface electromyography (EMG) is a noninvasive technique to record the activation signals of muscles when they are mechanically active. This signal is very small compared to the 60 Hz signal whic ...

Analog Modem Design Project

Introduction: We thought it would be interesting to try and construct a simple modem out of the ATMEL 8535. The main motivation for doing this was to test some DSP theories about the effects of transmission power, noise, and modulation technique on the bit error rate. Initially, we wanted to connect our modem to the public telephone network; however, the voltage, current, and bandwidth constraints over a ph ...
