Project 01 // Creative coding + sound

Musical
Instruments

Use the eBrain as a playable interface. Light controls pitch and musical gestures; buttons perform, record, and reshape sound.

Play the Theremin Open Groovebox
INSTRUMENT 01 // LIGHT → PITCH

Light Theremin

Move your hand above the light sensor and hear the reading become sound. Slide continuously like a classic theremin or lock the pitch to a musical scale.

  • One analog light sensor on A0
  • Optional GPIO 4 trigger button
  • Live waveform and pitch history
  • Room calibration and scale controls

Pocket Groovebox

Perform four musical voices with buttons, then hold a button and move over the sensor to draw a repeating musical gesture into the loop.

  • Four programmable buttons
  • One analog light sensor on A0
  • Drum, bass, chord, and lead voices
  • 16-step loop with mutation

The shared idea

Sense. Map. Perform. Remix.

Both instruments use the same creative-computing pattern. Once it works, change any layer to invent a different instrument.

  1. Sense the performer.
    Read light or a button state from the eBrain.
  2. Map the signal.
    Turn a sensor range into pitch, note choice, tone, or timing.
  3. Make it playable.
    Add calibration, visual feedback, and a clear performance gesture.
  4. Remix one layer.
    Change the sensor, sound engine, control gesture, scale, or physical enclosure.
