Satellite Solar Panel Orientation Tracker with 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.

In this project, you’ll build a light-seeking mechanism that uses four LDRs to detect the brightest direction and command two SG90 servos to point a small solar panel model towards the light source – exactly how satellites orient their vast solar arrays in orbit. It’s a hands-on introduction to space technology and feedback control systems that is as fun to build as it is to demonstrate.

What You'll Build

By assembling this kit, you’ll create a fully functional solar tracker that follows a torch or sunlight across a room. The quad-sensor setup ensures accurate positioning in both horizontal and vertical axes, mimicking the dual-axis movement used by real spacecraft. When finished, your tracker responds in real‑time to changing light conditions, a tangible demonstration of automation and renewable energy concepts that you can proudly showcase.

What You'll Learn

• Using a light-dependent resistor (LDR) as an analog sensor to measure brightness
• Servo motor control through PWM signals from Arduino Uno
• Reading multiple analog inputs and computing differentials to determine direction
• Simulating satellite orientation logic with a feedback loop and simple Arduino code

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is ideal for school students aged 5-15 (with adult supervision) discovering electronics, CBSE Class 11-12 students building physics or computer science projects, and ATL Tinkering Labs exploring satellite technology. It also serves as a hands-on introduction for B.Tech ECE/EEE first-year students and teams participating in space-themed competitions like the Smart India Hackathon junior track.

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.
