Ball Balancer PID Kit with Arduino Uno - Master Control Systems
Ball Balancer Kit with Arduino Uno & MPU6050 - Build a Real-Time PID Control System
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
A steel ball, a tilting beam, and a servo motor - your code makes them one smooth system. This kit puts you inside the logic of a real-time controller, where every sensor reading becomes a motor correction. Once built, you'll have a working demo of how robots maintain posture, drones hold altitude, and industrial PID loops keep processes stable.
What You'll Build
You'll assemble a single-axis platform that senses a ball's position using the MPU6050's accelerometer and gyroscope, then runs a PID algorithm on the Arduino Uno to command an MG996R servo. The result is a platform that actively rejects nudges and pushes the ball back to centre - a tangible, physical proof of control theory.
What You'll Learn
- Tuning proportional, integral, and derivative gains on real hardware
- Reading MPU6050 motion data over I2C and extracting relative angle
- Controlling a high-torque servo with feedback for precise positioning
- Architecting a closed-loop system from sensor input to actuator output

Who This Kit Is For
CBSE Class 11-12 students taking physics or computer science with a project will find a direct application of PID looping and sensor fusion. B.Tech ECE/EEE undergraduates can reinforce control system fundamentals hands-on. Smart India Hackathon participants and ATL Tinkering Lab facilitators get a ready-to-demonstrate mechatronics module, while IIT/NIT/VIT/BITS makers explore embedded real-time systems in depth.
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 inside the box to open an AI companion trained on this project. It walks through soldering, wiring, and calibration. You can also reach out on WhatsApp; a real person responds within a workday.
Do I need to solder components?
Yes, you'll solder resistors, capacitors, and headers onto the supplied PCB prototype board. The guide includes a clear placement diagram, and the AI companion explains each joint if you're new to soldering.
How do I tune the PID gains properly?
The companion provides a structured process: start with P only, note oscillation, introduce D to dampen, then add I to eliminate steady-state error. You'll also get a pre-tuned baseline code you can load and observe before customising.
Can I extend this to a two-axis ball balancer later?
Absolutely. The core skills - MPU6050 data fusion, servo control, and PID - transfer directly. You'd need an additional servo and a gimbal structure; the kit's firmware is open source and commented so you can adapt it.
MPU6050 on a single-axis tilting platform uses PID to balance a ball in the centre using a servo.
