Master PID Control with Magnetic Levitation Arduino Kit - Build It
Magnetic Levitation Controller Kit with Arduino Uno - Master PID Control While Levitating a Steel Ball
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 a iron ball hovering in mid-air, held steady by an invisible force you control. This kit transforms Arduino Uno, a Hall sensor, and an electromagnet into a complete closed-loop levitation system. You'll write a real-time PID algorithm that reads the ball's position 100 times a second and adjusts current to keep it floating - a perfect capstone for control systems coursework, Smart India Hackathon, or a final-year B.Tech project.
What You'll Build
You'll assemble a fully functional magnetic levitator: an electromagnet suspended above a Hall sensor, with a ferromagnetic ball levitating in between. The OLED display shows live position error, current draw, and PID output. Once tuned, the ball floats with sub-millimeter stability, and you can even tap it gently to watch the controller compensate - a mesmerising demonstration of classical control theory in action.
What You'll Learn
- Tune PID constants (proportional, integral, derivative) for stable levitation without oscillation
- Calibrate an A3144 Hall effect sensor and linearise its output to measure sub-millimetre ball displacement
- PWM-drive an IRF540N MOSFET to regulate electromagnet current with an INA219 current sensor for feedback
- Implement sensor fusion and real-time control loops on Arduino Uno with interrupt-driven timing

Who This Kit Is For
This advanced kit targets B.Tech and M.Tech students in ECE, EEE, and mechatronics who need a hands-on control system project. It's ideal for Smart India Hackathon teams, IIT/NIT/VIT/BITS lab assignments, and serious hobbyists who have basic Arduino coding experience. If you've already built simpler sensor projects and want to dive deep into feedback loops and automatic control, this is your next challenge.
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?
Scan the QR code to launch the AI companion that has debugged levitation builds before; if you need a human, our team replies on WhatsApp within hours.
Do I need prior experience with PID control?
No. The AI companion explains how P, I, and D gains affect the ball's behaviour from first principles, with interactive tuning examples you can run on the OLED.
Can the levitation be demonstrated without an oscilloscope?
Absolutely. The included OLED shows real-time Hall sensor voltage, current reading, and PID error - all the signals you'd normally scope, right on the board.
Is this kit suitable for my final year B.Tech project?
Yes. The levitation system meets curriculum requirements for control systems lab, and you'll have a full documented project demonstrating sensor feedback, actuator drive, and algorithmic tuning.
Hall sensor detects ferromagnet position. PID controls electromagnet current to levitate ball mid-air.
