This project transforms a standard Arduino into a multi-octave digital piano using a series of high-quality tactile switches and a polyphonic sound engine.
Frequency Mapping Kernel: The Arduino monitors a matrix of tactile buttons. The firmware uses a chromatic lookup table to map each button to its precise frequency (e.g., A4 = 440Hz).
Square-Wave Audio Engine: Uses the tone() function to generate the musical pitches. The project explores the use of passive RC filters to smooth the raw square waves into a more pleasant, "analog-like" timber for the keys.
Performance
Low-Latency Polling: Optimized to scan the entire 12-key button array every 1ms, ensuring that the musician experiences zero-lag between the physical press and the sound generation.
