Hello Friends, In this tutorial we will make a “Digital Stop Watch” using an AVR ATmega8 Microcontroller. This will help you learn many concepts like Multiplexed Seven Segment Display Interfacing Using AVR Timers Using Interrupts And many others too. The code is written in C language for avr-gcc (WinAVR) . Steps to Build the “Digital Stop Watch” […]

Introduction Have you ever imagined, “What does that cable I plug into my iPod every day actually do, and how do I take advantage of it for myself?” We did too, and that’s what we aimed to do with our 476 project. The iPod is, of course, the popular digital music player developed by Apple. The heart of the project

Introduction This project implements a high speed data acquisition system using Mega32 microcontrollers and a Controller Area Network (CAN). Recording data is essential to testing and developing a racecar. Recording what each sensor is doing can tell an engineering how the car is performing, and most importantly, how to make it faster. A well outfitted

Microcontroller understands only digital language. However, the inputs available from the environment to the microcontroller are mostly analog in nature, i.e., they vary continuously with time. In order to understand the inputs by the digital processor, a device called Analog to Digital Converter (ADC) is used. As the name suggests this peripheral gathers the analog information

SingLock is a pitch-based security system based on ATMEL MEGA1284P microcontroller featuring two password protection stages: one based on a 4-digit numeric personal identification number inputted via the keypad and another based on two pitches inputted via the microphone. Most security systems we find today are keypad and/or keyboard-based. Speech, rather than button-pressing and/or typing,

The project described here is a digital implementation of “book cricket game” which students normally use to play in their childhood time. The heart of the project is 8 bit MCU from AVR family called ATtiny85. ATtiny85 are small and cheap microcontrollers which are convenient for running simple programs with low footprint. The software used

Introduction The goal of this project is to design an algorithm for a real-time digital guitar tuner and implement it using an Atmel AT90S8535 microcontroller. Each of the six strings of a guitar has a unique fundamental frequency, and our goal is to measure this frequency and compare it to the correct frequency. This project

Introduction: Motivation for Design The Mechanix is a motorized guitar tuner for a standard 6-string electric or acoustic fixed bridge guitar. Named in honor of Megadeth guitar legend Dave Mustaine, the Mechanix is a unique and innovative product which has numerous patent possibilities. Traditional handheld guitar tuners are passive; they tell the user whether the

Introduction The Music Wand is a device that optically reads printed sheet music in real-time and synthesizes the notes which are read from the page. The device uses a linear image sensor mounted on the end of a handheld wand to scan printed sheet music and identify the note pitches. For each note detected, a
