Easy Theremin Uses ESP32
Hackaday • • technology
Key Points:
- The Theremin, known for its distinctive electronic sounds popular in mid-20th-century sci-fi films, can be built using modern technology.
- EricCycles created a Theremin primarily using an ESP32 microcontroller with minimal additional circuitry.
- The device controls pitch and volume by detecting hand proximity to two antennas using the ESP32's capacitive touch capabilities.
- The ESP32 synthesizes the waveform based on hand movements and outputs the sound through its onboard digital-to-analog converter to external speakers.
