Motor PID Speed Controller Kit with Arduino Uno + Motor
Build a Precision Motor PID Speed Controller with Arduino Uno – Complete Project 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.
Take precise control of motor speed with a feedback system used in robotics and automation. You’ll build a PID speed controller that reads actual RPM from an encoder, compares it to a serial-defined setpoint, and adjusts the L298N driver output in real time. The 16x2 LCD shows both target and current speed, turning you into a motion control expert.
What You’ll Build
Build a self-correcting motor speed controller that maintains a constant RPM regardless of load changes. Once assembled, you can dial in a target speed from the serial monitor and watch the PID algorithm automatically adjust power to the motor, with live feedback on the LCD. This project forms the core of any motion control system, from conveyor belts to robot arms.
What You’ll Learn
- Implement a closed-loop PID control algorithm on Arduino
- Interface a quadrature encoder (LM393) to measure motor RPM
- Tune proportional, integral, and derivative gains for stable response
- Drive a DC motor using an L298N H-bridge with built-in flyback protection

Who This Kit Is For
Ideal for CBSE Class 11–12 students pursuing electronics or computer science, this kit bridges textbook theory with hands-on PID tuning. B.Tech ECE, EEE, and mechatronics students at NITs, VIT, or BITS Pilani will find it perfect for control systems lab projects. ATL Tinkering Lab mentors and Smart India Hackathon participants can prototype motor-based solutions quickly with pre-tested components.
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 scans your QR code and provides real-time troubleshooting. If you need human help, WhatsApp us directly for a callback or text support.
How do I tune the PID gains for different loads?
The AI companion walks you through Ziegler-Nichols and manual tuning methods, explaining how to adjust Kp, Ki, and Kd using serial feedback while observing the RPM response on the LCD.
Can I use this kit with a different Arduino board?
The included Uno R3 is ideal, but the AI companion can adapt pin mappings for Mega or Nano if you already own them. The firmware is fully cross-compatible.
Does the encoder provide accurate RPM readings?
Yes, the LM393 encoder delivers 20 pulses per revolution. Our interrupt-based firmware calculates RPM to ±1% accuracy, and you can calibrate offsets via the serial monitor.
L298N drives motor with encoder feedback PID loop. Serial tunable gains. LCD shows setpoint and actual RPM.
