Arduino Laser Harp

February 01, 2013 By: admin Category: Arduino, Audio, Microcontroller, Miscellaneous No Comments →

This cool music instrument is built by SthepenHobley based on Arduino. This harp doesn’t make sound itself but generates a stream of MIDI data to drive an audio synthesizer. In other word, Laser Harp works as MIDI controller. The way it works is simple, when the player’s hand interrupts the laser beam Theremin, the photocell […]

AVR Auto Composing Piano

This ATmega644-based smart piano can composes music of your own taste automatically. What you have to do is select a mood of the music and play two notes upon which the music is based, and then let the piano create the music for you. You can also train the piano by first playing several pieces […]

PIC Doorbell

This PIC10F322-based Doorbell replaces your loud and boring Doorbell with playing your desired tunes in wave format. The project need I2C EEPROM chip to store the WAV files since PIC10F322 only has 512 bytes of flash and 64 bytes of RAM. If you have PIC chip with bigger memory then you can skip the EEPROM.

Stereo Audio with Arduino

December 10, 2012 By: admin Category: Arduino, Audio No Comments →

The project shows you how to use Arduino and TLC7528 to produce stereo audio, 2 independent channels of audio. With stereo audio you can achieve some interesting and quite fun auditory effects since each ear is hearing its own independent channel of sound, for example, “3D audio” spatial effects, binaural beats, and panning.
