More about Granular Synthesis on wikipedia

Hardware:

• Arduino Pro Mini board
• USBASP programmer
• 4 potentiometers and one infrared distance sensor are connected to Analog (0-5) pins on the Arduino board (real mapping must be determined)
• MIDI input using RxD signal form serial interface (making the serial interface and arduino bootloader not usable for programming)
• Audio output on Digital pin 3 (1-bit DAC/8-bits PWM/31.25kHz)
• one spin plate sensor from a hard drive motor + plates (unused)
• Amplifier + speaker module / housing

Software:

• Two voices granular Synthetizer
• Controls: Synchronization, and Freq (pitch) & Decay for each voice (5 controls)

Sound mappings:

• linear
• logarithmic
• major pentatonic
• pentatonic
• minor pentatonic
• major diatonic
• minor diatonic
