Spring Constant Tester

About this project

Build a precision spring constant measurement system using Arduino Uno with ultrasonic distance sensor to measure spring extension under load. Apply Hooke's Law F = kx to calculate spring constant, determine elastic modulus, measure spring energy storage, and verify linear elasticity region. Perfect for understanding material elasticity, stress-strain relationships, mechanical testing fundamentals, and spring design principles in mechanical systems.
