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, […]

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

The circuit presented here demonstrates how to generate Audible Frequency from an AVR Microcontroller. The output of Microcontroller is always digital so to generate audible sound at the outset first it needs to be converted into Analog. A DAC (Digital to Analog Converter) is used for this purpose. Microcontroller generates sine wave of Audible Frequency using DAC.
