Introduction We were inspired to build an ultrasonic security system for our final project by our housing situation this summer. Security is an important part of home, especially if we are going to share a house with prior strangers without a lock on our room door. Yes, that is the situation we are walking into […]

In this project, we are going to make a Fire Alert System using ATMEGA8 microcontroller and fire sensor. Fire sensor can be of any type, however we are using IR (Infrared) based Fire Sensor. Although IR based Fire Sensors have some disadvantages mostly of inaccuracy, it is the cheapest and easiest way to detect fire. IR Based Fire sensors

Or, an exercise in input and output multiplexing, and working with bits. And a submission for the Arduino contest. This is an implementation of a tic tac toe game using a 3×3 array of bicoloured LEDs for a display, a simple resistive touchpad, and an Arduino to tie everything together. To see how it works,

I. Introduction We used the Wiimote’s IR tracking capability and Bluetooth to wirelessly control a robotic crane arm. The Wiimote is a powerful gadget and we wanted to build a new hack with it. Our crane is composed of three servo motors, one of which is connected to a gripper. The servos are controlled by

This is a simple procedure to play PCM audio on any AVR microcontroller. AVR’s high speed PWM is used to play the audio. It almost sound fine and can be used for simple projects that require sound effects. The code is compiled in winavr GCC compiler. The microcontroller used is ATmega32, though any AVR processor

Introduction Sound Bite Our project implements a tuner that continuously outputs the frequency of an input microphone signal with a high degree of accuracy. Project Summary This project’s goal is to use a sensitive microphone, computer speakers and a properly designed circuit so that for an input microphone signal a relatively noiseless sinusoidal signal is

Introduction For our ECE 4760 final project, we designed and built an electric guitar pedalboard that will take in an analog audio signal from a guitar and add analog effects such as equalization, gain control, as well as digital effects such as distortion, compression, and chorus. The processed sound will be outputted through a ¼”

Our Keyboard Synthesizer project aims to create a multi-instrument keyboard that can record several different synthesized instruments and play back the track simultaneously. We took a children’s toy keyboard and adapted the printed circuit board within to play a range of notes from various musical instruments. Our user interface is a phone-style keypad for command

Our final project is to build a multifunctional music box. This music box can generate different songs in different instrument sounds, i.e. piano, organ, by FM synthesis. The theme and harmony are in two different channels. Besides, the music box can also be electrical piano by which users can play their own music, the piano

markov summary Traditional music boxes play one or two tunes very well, but are not very interactive. Put differently, they have a high quality of synthesis, but a fixed-pattern note sequencer and fixed tonal quality. I wanted to build a device which would play an interesting music-like note sequence, which constantly changed and evolved, with
