Theremin with Cypress' PSoC Analog Coprocessor!
Cypress's PSoC Analog Coprocessor MCU has been used to create a Theremin instrument!
So what is a theremin? A theremin is an electronic musical instrument that does not require direct physical contact on the instrument, it uses proximity sensors to detect a nearby physical object, such as your hand.
For the implementation, Cypress' best-in-class CapSense® is used to drive the proximity sensors on the CY8CKIT-024 board, which allows for distances of up to 10cm,
as well as programmable digital and analog resources within the PSoC MCU to create the tone and pitch for the instrument.
The on-board proximity sensors are used to adjust the tone and volume of the instrument, while the internal Universal Analog Block (UAB) is configured as a 13-bit DAC
for creating digital audio and a Timer/Counter/PWM (TCPWM) is used to create the desired tone for the instrument.
