Final Proposal
I am planning to do a synthesizer and program it with the Atmega328p microcontroller. Here is a reference I found, and it is programmed by the Arduino Uno board.
(5X) 5K potentiometer
(3X) LEDs
(1X) Toggle switch
(1X) Light Dependent Photo Resistor
(1X) Atmega328P
(1X) Switch
(1X) 1/8" Audio Jack
(3X) 10K ohm resistors
(3X) 220 resistors
(1X) 9V battery
(1X) 9V battery clip
“Sound is created by playing the same sound grain, or samples (small pieces of around 1 to 50ms) over and over again at very high speed. Our ears and brains turn this into an audible hybrid of the repetition rate and the original grain, and it sounds like a constant tone.
The grain consists of two triangular waves of adjustable frequency, and adjustable decay rate.
The repetition rate is set by another control.”
