This project is an Arduino based step sequencer, synthesizer and sound effects box.
The user interface is kept very simple, with just four knobs, three push buttons, 8 LEDs and a power switch. The speaker is connected straight to a pin on the Arduino via the volume knob - everything is done in the Arduino using PWM to generate analog waveforms. The LEDs indicate the current step in sequencing mode, and provide light patterns in noise modes.
The basic features are:
16-step programable sequencer with adjustable frequency and duration for each step
synthesizer with 4 output waveforms (sine, square, triangle and sawtooth)
noise generation (sirens, laser beam, random noise)
Great construction, this Theremin using LC oscillator circuit generate the frequency signal like a capacitive sensor then feed to the Arduino board for generating sound using software. The position of the player’s hands controlling the frequency signal(sound).[link]

i have made a physical interface for the Arduino drum samples (as seen in a previous post). Two 8-way DIP switches control the beat, a pot controls the sampling rate (and therefore pitch) and another pot controls the time between notes.The two dip switches work in tandem so that each 1/8th note can have four possibilities (two bits) worth).
Theremin has been a quite popular project over the last few years especially after Arduino is risen. Here is one which has been sent to me by Nick Hardeman. This is Theremin Style Instrument based on Arduino. Nick Hardeman writes: Read more…
