Summary of Arduino-based theremin
The article describes a simple Arduino-based Theremin module using a TTL LC-type oscillator. This device operates via near-field coupling between the player's hands and metal antennas to control pitch and volume. Beyond music, it functions as a generic sensor for controlling motors or integrating with software like Processing and Max.
Parts used in the Arduino Theremin:
- Arduino
- TTL LC-type oscillator
- Metal antennas
- Variable-frequency oscillator
- Fixed-frequency oscillator
Theremin is one of the most exiting musical instruments ever made, mainly because of its “quite odd” playing method. Infact, its working principle is based on near-filed coupling between the hands of the theremin player and two metal antennas, used to determine the pitch of a variable-frequency oscillator and to adjust the volume of the output signal, respectively.
Several theremin implementation are possible, such as the “original” analog one (based on the mixing of two sine waves originated by a fixed-frequency oscillator and a variable-frequency one) and those based on digital techniques.
LabIII guys implemented a nice and simple Arduino theremin module, based on a TTL LC-type oscillator, usable not only to play electronic music, but also as a generic sensing-device, for example to control motors and/or to work with Processing, Max etc.
