Vibration Frequency Meter

About this project

Build a vibration analysis system using Arduino Uno with piezoelectric sensor to measure frequency, amplitude, and acceleration of mechanical vibrations. Detect vibration events, perform FFT analysis to find dominant frequency, calculate displacement and velocity, and display real-time vibration data on LCD. Perfect for understanding vibration theory, resonance phenomena, structural dynamics, predictive maintenance, and harmonic analysis in mechanical systems.
