Smooth Tension Coiling: Rope Coiler Tension Controller Kit with Arduino Uno & Stepper Motor

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

Picture a spooling station that winds rope evenly at exactly the tension you command — no slack coils, no jerky overtightening, just smooth, programmable pulling. With this kit, you build a closed-loop tension controller that uses a NEMA 17 stepper to drive a winding drum while a load cell reads the actual pull force. A PID loop running on an Arduino Uno constantly compares measured tension to your setpoint and adjusts motor speed to keep winding perfectly consistent.

What You'll Build

A motorized drum that feeds and coils rope under constant tension, displayed live on an OLED screen. You can use it to neatly manage cables for a robotic arm, maintain controlled pull in a zipline brake simulator, or showcase industrial winding principles in a science exhibition. The final assembly is a portable, reprogrammable demonstration of real-time control.

What You'll Learn

• Implementing a PID controller in Arduino code to maintain real-time tension without oscillation
• Interfacing a load cell with the HX711 amplifier for precise force measurement down to gram-level changes
• Driving a NEMA 17 stepper motor with an A4988 driver and configuring microstepping for smooth motion
• Displaying live force readings and setpoint adjustments on a 0.96‑inch OLED using I2C communication

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate kit is designed for CBSE Class 11–12 students exploring applied physics and control systems, B.Tech ECE/EEE undergraduates building mechatronics prototypes, and Smart India Hackathon teams working on automated material handling solutions. It also suits ATL Tinkering Lab projects where force sensing and actuator control overlap, as well as hobbyists preparing for engineering college exhibitions at IITs, NITs, or BITS Pilani.

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.
