The StompByte plays 8-bit sampled sounds when the button is tapped. Holding the button cycles through different sounds. It can be used as a foot percussion device, and even plays a few simple rhythm patterns. It can be powered by a 9-Volt battery or AC adapter.

Stomping the button triggers a sound. Holding the button for two seconds switches to the next sound/pattern. Patterns play a step with each press and release of the button. There are 10 samples and 3 patterns:

  1. muted kick
  2. rock kick
  3. tr808 kick
  4. woodblock
  5. cross stick
  6. tambourine
  7. handclap
  8. 8bit bump
  9. 8bit fireball
  10. 8bit jump
  11. pattern: rock kick – woodblock – tambourine – woodblock
  12. pattern: tr808 kick – tambourine – handclap – tambourine
  13. pattern: 8bit bonk – 8bit fireball – 8bit jump – 8bit fireball

The sound is produced by an ATMega328p microcontroller, the same MCU as the Arduino Uno. The audio signal from the pins goes directly to the TRS audio jack - all the rest of the components are just power and timing for the MCU.
