Worm Gear Slow Drive Demo Kit with Arduino Uno - See Gear Ratios in Action

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Watch a fast-spinning DC motor turn into a slow, powerful 1 RPM output through a real worm gear drive. This kit lets you build a desktop demo that displays accurate speed on an OLED screen while teaching the mechanics behind elevators, winches, and robot arms. Every part snaps together on a breadboard—no soldering required.

What You'll Build

A compact Arduino station that powers a worm gear motor, measures its rotation with an encoder, and shows live RPM data. You’ll see the final shaft turn exactly once per minute, making gear reduction tangible and easy to grasp for young learners and curious grown-ups alike.

What You'll Learn

• How worm gear teeth mesh, reduce speed, and multiply torque
• Calculate gear ratio using motor RPM vs. output RPM
• Read a digital encoder to measure rotational speed
• Display sensor data on a 0.96-inch OLED with Arduino code

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11–12 physics students experimenting with simple machines, ATL Tinkering Lab facilitators running gear demos, and first-year engineering aspirants at IITs, NITs, or VIT who want a quick proof-of-concept. Parents can also use this kit to introduce kids as young as 5 to the magic of gears and motors with adult supervision.

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.
