Arduino Mechanical Advantage Kit: Measure Levers, Pulleys & Gears
Master Mechanical Advantage: Arduino Force Ratio Kit for Levers, Pulleys & Gears
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine measuring exactly how much a lever multiplies force - not from a textbook diagram, but from a live sensor reading on an LCD. This kit turns abstract mechanical advantage formulas into tangible, measurable data with two load cells and an Arduino Uno. It's a ready-made instrument for physics experiments, letting you directly measure input and output forces on levers, pulleys, and gear trains.
What You'll Build
A dual-load-cell measurement station that displays real-time force readings and calculates the mechanical advantage ratio. You'll configure it to test all three classes of levers, different pulley arrangements, and gear sets, then log time-stamped data to evaluate efficiency and friction losses.
What You'll Learn
- Calibrate load cells precisely using the HX711 amplifier for accurate force measurement
- Program the Arduino to simultaneously read two force sensors and display the ratio on a 16x2 LCD
- Apply concepts of ideal and actual mechanical advantage to real simple machines
- Record experiments with the DS3231 RTC module to analyse data trends and repeatability

Who This Kit Is For
CBSE Class 11-12 physics students performing investigatory projects on laws of motion and machines. First-year B.Tech ECE/EEE students learning sensor interfacing and instrumentation. ATL Tinkering Labs and Smart India Hackathon teams prototyping force-based smart systems.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Open the AI companion via the QR code inside the box or message us on WhatsApp. It knows this exact project and will guide you step by step.
Can I test different simple machines with this kit?
Yes. The two load cells can be mounted to measure forces on any lever, pulley system, or gear train you construct. You will need to build the mechanical structures yourself using common materials.
Does this kit include levers or pulleys?
No, it provides the electronic measurement system. You can build the mechanical parts from cardboard, wood, or 3D-printed components. The load cells attach easily with simple mounting holes.
Is this suitable for a CBSE Class 12 physics project?
Absolutely. It provides quantitative force data and mechanical advantage calculations, perfect for an investigatory project. The RTC lets you log multiple trials for analysis.
Two load cells measure input and output force of levers, pulleys and gears to calculate mechanical advantage.
