GearForge - Arduino Gear Ratio & Mechanical Advantage Analyzer

About this project

Build a gear train analysis system using Arduino Uno with dual IR photogate sensors to measure input and output shaft RPM simultaneously. Calculate gear ratio, mechanical advantage, velocity ratio, torque multiplication, and transmission efficiency. Perfect for understanding power transmission fundamentals, gear train kinematics, torque-speed relationships, and mechanical system design in drivetrain and gearbox applications.
