Introduction We constructed an analog-to-digital guitar that captures an input signal and uses the waveform zero-crossings to determine whether the note is at the correct frequency. The hope was that this frequency tuner could be used in a home setting where each of us can tune our own guitars. While a great number of students […]

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

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.
