This React-based Drum Machine app lets users play audio samples by clicking pads or pressing keyboard keys (Q, W, E, A, S, D, Z, X, C). Each pad triggers a unique sound (e.g., Heater kits, claps, cymbals), with a display showing the active sound. Built to meet freeCodeCamp's test requirements, it demonstrates React state/event handling, dynamic UI updates, and responsive CSS styling.
