Pendulum Gravity Meter

About this project

Build a precision pendulum oscillation analyzer using Arduino Uno with LDR break-beam sensor for period measurement and gravity constant calculation. Measure time period of simple pendulum, calculate local gravity (g), verify T = 2π√(L/g) relationship, and display real-time oscillation data on LCD. Perfect for understanding simple harmonic motion (SHM), periodic motion fundamentals, gravity measurement techniques, and experimental physics validation in mechanical dynamics.
