Linear Actuator Position Control Kit — Master Feedback Loops with Arduino Uno and OLED

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 commanding a linear actuator to extend to exactly 50.0 mm, and watching an OLED display track its movement in real time — all governed by a proportional control algorithm you wire and code on the Arduino Uno. This kit gives you the exact hardware and pre-tested circuits to explore one of the most fundamental concepts in mechatronics: using potentiometer feedback to control position with a DC linear actuator.

What You'll Build

You'll assemble a complete motor-drive and feedback interface on a breadboard. A 10kΩ potentiometer acts as the actuator's position sensor (mimicking a linear slider mechanism), while a second potentiometer sets your target position. The Arduino reads both, computes the error, and drives the L298N motor driver to move the actuator proportionally. The result: smooth, repeatable positioning visible on a crisp 0.96-inch OLED display.

What You'll Learn

• Wire a DC motor driver (L298N) with Arduino to control actuator speed and direction
• Use a potentiometer voltage divider as an analog position feedback sensor
• Implement a proportional (P) control loop in C++ on the Arduino IDE
• Display real-time system variables (setpoint, actual position, error) on an OLED via I2C

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for CBSE Class 11‑12 students exploring control systems in their physics practicals, B.Tech ECE/EEE first‑years building a mini project on feedback loops, and Smart India Hackathon participants prototyping a precision actuator mechanism. ATL Tinkering Lab mentors will find it an ideal introduction to sensor‑actuator loops. If you have a DC linear actuator with a potentiometer feedback (or a slider‑actuator setup), this kit makes the control side plug‑and‑breadboard ready.
