This simple audio spectrum analyzer is based on PIC32 proto board on PIC32MX360F512L with 320×240px colour LCD (LVC75Z779 Eval Board). The analyzer can be connected to unamplified audio source like PC’s sound card, MP3 player and so on. SSD1928 Module Schematic diagram The reference voltage of ADC is set to 1V with potentiometer connected to […]

Overview A Pulse Width Modulation (PWM) output from a PIC microcontroller can be used to play tones on a piezo speaker. With this, musical scales and simple songs can be played on the piezo speaker. Piezoelectric speakers operate by the converse piezoelectric effect: when a voltage is applied across the terminals, the piezoelectric material in

The fastest finger press quiz buzzer is very popular in school, Collage, different T.V. show, different quiz competition. Here in my pic microcontroller based fastest finger press quiz buzzer project you will find four tables with push button. For any instant if four teams on four tables press the push button then it will glow

Introduction We built a miniature recording studio using the PIC32 that allows the user to record a short soundtrack, play it back, then layer on additional sounds. We chose to support sounds for three tonal instruments: piano, guitar, and bass, as well as eight unique drum sounds. The user can play a full octave on

INTRODUCTION Our Smart Station hardware consists of a PIC32MX250 microcontroller with a 3.5mm jack for speakers, a TFT display, keypad, NeoPixel LED ring, microphone, and a host of I2C environmental sensor breakouts: i.e. accelerometer, temperature, humidity, and luminosity sensor breakouts. All of the electronics are neatly contained within a 3D printed casing. Our Smart Station
Introduction: We created our own version of Guitar Hero which can play any song that has a MIDI file by using our custom controller and UI. We are big fans of the original Guitar Hero game, but felt limited by its inability to only play a set of songs. We came up with the solution, Guitar

Introduction For this design project, we built a portable digital synthesizer capable of creating a wide variety of sounds designed by the user. The system consisted of a full octave (13 key) keyboard with two-voice polyphony, three rotary encoders for user input, a TFT LCD for visual display, and an SPI DAC for audio output.

A while back I made a blog post about a PIC10F200 Project: The Annoy. In this project they combined the simplicity in design along with the creativeness that I always look for, into a project with no real use other than for fun. However, the project seemed a little too large and we felt we

INTRODUCTION We constructed a triangular arrangement of microphones to localize the direction an arbitrary sound is coming from. By recording input from the three microphones, we can cross-correlate the recordings to identify the time delay between the audio recordings. Since the physical placement of the three microphones are known, the direction of the sound can

High-level Design The goal of this project is to create an electronic flute. The musical instruments like keyboards, guitars, etc. have adjustable keys in order to play sounds at different scales. However, flutes are designed for only one scale and therefore need to be changed to play music on another scale. Hence, our electronic flute
