Motor Impedance Control Loop Kit with Arduino Uno + Motor
Master Virtual Spring-Damper Motor Control with Arduino Uno Impedance Control Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Step into real-world control system engineering by building a DC motor that behaves exactly like a mechanical spring-damper. Using current and position feedback, this kit lets you program a virtual mechanical impedance into an Arduino Uno — creating a motor that pushes back with tunable stiffness and damping when you twist the shaft. It is the same principle used in advanced haptic interfaces, collaborative robots, and prosthetics.
What You'll Build
You will assemble a closed-loop motor drive that continuously reads shaft angle and motor current. The Arduino runs an impedance control algorithm, making the motor resist external motion with a force proportional to its displacement (virtual spring) and velocity (virtual damper). The real-time response and parameter settings are displayed on an OLED, giving you a physical testbed to explore force-control dynamics at the component level.
What You'll Learn
- Sensor fusion using AS5600 magnetic encoder for angle and INA219/ACS712 for accurate current sensing
- Designing cascaded PID loops for current and position to realize stable impedance behavior
- Mapping spring stiffness and damping coefficient formulas to Arduino code and observing their effect on the motor shaft
- Hardware integration of an H-bridge motor driver with 12V power and protection circuits on a prototype board

Who This Kit Is For
This kit is made for final-year B.Tech students (ECE, EEE, Mechanical) tackling control system or mechatronics capstone projects. Smart India Hackathon participants will find a ready-to-deploy force-feedback module that can be integrated into larger prototypes. Researchers at IITs, NITs, VIT, BITS, or any engineering college looking to demonstrate impedance control without building all circuits from scratch will get a proven, replayable experiment.
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?
The AI companion walks through every connection, calibration, and code upload. If you need human help, just send a WhatsApp message — we'll help you debug within 12 hours.
What impedance parameters can I tune?
You can adjust virtual spring stiffness (N⋅m/rad) and damping coefficient (N⋅m·s/rad) directly in the Arduino code. The OLED shows real-time applied torque and angular displacement, so you can see the immediate effect of changing these values.
Do I need to solder?
Yes, the sensor and driver circuits are best assembled on the included prototype board using the soldering iron and solder wire provided. Full wiring diagrams are part of the project guide.
Can this kit serve as a capstone or mini-project demonstration?
Absolutely. The open-source code, data logging capability, and documented theory make it easy to present as a full control-system project. Many students have used this exact setup to earn top grades and hackathon recognition.
Current and position feedback implement impedance control on DC motor. Adjustable virtual spring-damper.
