Build a Dual-Axis Solar Tracker for Satellites & Space Projects — Arduino Uno + LDR 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.

When satellites orbit Earth, their solar panels must constantly reorient toward the Sun to maintain power — this kit recreates that critical system on your workbench. You’ll assemble a quad-LDR sensor array that feeds light direction data to an Arduino Uno, then program two servo motors to tilt and pan a small solar panel for maximum energy capture. It’s the same closed-loop control logic used in real spacecraft, shrunk into a hands-on 3-hour build.

What You'll Build

A fully functional solar tracking test rig. Four light-dependent resistors detect brightness from all sides, an Arduino Uno computes the vector to the strongest light source, and a pair of SG90 servos positions a panel mount (panel not included) to face it directly. The 0.96-inch OLED displays real-time angle data so you can verify tracking accuracy. By moving a flashlight around the sensor, you’ll watch the mechanism follow it — proving the concept behind tens of thousands of orbiting solar arrays.

What You'll Learn

• How to interface multiple LDR sensors with Arduino and read analog values to infer light direction.
• Dual-axis servo control using PWM signals and the Arduino servo library.
• Closed-loop control algorithms (simple difference-based tracking) for real-time reorientation.
• Displaying sensor data and tracker angles on an OLED via I2C communication.

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate kit is ideal for CBSE Class 11 and 12 students building physics investigatory projects on renewable energy, B.Tech ECE/EEE first-year students tackling mini projects at NITs, IITs, or VIT, and ATL Tinkering Lab participants preparing for the Smart India Hackathon. If you’ve completed a basic Arduino starter kit and want a deeper dive into sensor fusion and motion control with a real satellite-engineering use case, this is your next step.

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.
