Web-Tunable PID Motor Controller
Web-Tunable PID Motor Controller – Arduino UNO + Encoder + Linux Web Dashboard
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 a bare DC motor with encoder feedback and turn it into a precision speed controller you can tune from any browser. This kit merges a real-time Arduino PID loop with a Linux-hosted web interface that lets you adjust Kp, Ki, Kd on the fly while watching motor response graphed live. It’s the exact workflow used in robotics drives, CNC spindles, and industrial positioning – shrunk to your workbench.
What You'll Build
You’ll assemble a complete closed-loop motor system: 12V geared motor, quadrature encoder, L298N driver, buck converter, and an OLED that displays setpoint vs. actual RPM. On a Linux machine (your laptop, Raspberry Pi, or even a virtual machine), you serve a web UI that sends tuning commands over serial. Every parameter change reflects instantly in the motor’s behaviour, giving you an intuitive grasp of derivative kick, integral windup, and response damping.
What You'll Learn
- Implement a PID control algorithm on Arduino UNO with microsecond-accurate timing
- Read quadrature encoder pulses to calculate real RPM and direction
- Build a responsive web dashboard using Python/Flask or Node.js that communicates with the controller over USB
- Map real-world tuning effects: overshoot, settling time, and stability margins while the motor runs

Who This Kit Is For
This kit is designed for B.Tech ECE / EEE / Mechatronics students working on control systems coursework, Smart India Hackathon teams prototyping motor-driven solutions, and anyone preparing a final-year project that needs a documented PID implementation. It’s also popular in IIT, NIT, VIT, and BITS labs where faculty want a ready-to-go tuning experiment instead of wiring from scratch.
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 you through every connection and code upload. You can also drop a message on WhatsApp – a real engineer who built this kit will respond within hours.
Do I need a separate Linux computer to run the web UI?
The web dashboard can run on any Linux machine with Python – even a laptop or a cloud VM. We include setup scripts and a pre-written server that works out of the box.
Can I use this kit for my engineering final year project?
Absolutely. The PID control with live tuning and OLED feedback meets most university project requirements. You’ll receive a complete circuit diagram and documented code that you can adapt and cite in your report.
Is the soldering iron included meant for surface-mount components?
The included soldering iron is a standard through-hole type – ideal for the prototype board and all components in this kit. No SMD soldering required.
Linux serves a PID tuning web UI. STM32 sketch runs the PID loop on a DC motor encoder in real time.
