Satellite Solar Array Simulator Kit with Arduino Uno and LDR
Satellite Solar Array Simulator Kit with Arduino Uno and LDR Sensors
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit transforms an Arduino Uno into a working solar array orientation simulator. Four light-dependent resistors (LDRs) detect a moving light source, and two SG90 servos automatically adjust to keep a virtual solar panel pointed straight at it - the same closed-loop tracking principle used in ISRO's satellites. Perfect for students exploring space technology or preparing a Science & Technology Exhibition project.
What You'll Build
A motorised twin-axis light tracker that continuously adjusts to follow a flashlight or the sun. The quad-LDR sensor module reads differential light levels, the Arduino computes the optimal solar panel angle, and two micro servos physically rotate the platform in pitch and yaw. In the process, you'll create a miniature model of how a satellite's solar array drive assembly (SADA) works.
What You'll Learn
- Wiring and reading multiple LDR sensors with Arduino analog inputs
- Coding proportional-derivative control logic to balance light readings from four sensors
- Calibrating servo positions for smooth, precise mechanical tracking
- Understanding the engineering behind spacecraft solar panel pointing systems

Who This Kit Is For
Beginners in STEM: CBSE Class 11-12 physics and computer science students, ATL Tinkering Lab participants, and first-year engineering undergraduates (B.Tech ECE, EEE) at IIT, NIT, VIT, or BITS Pilani. It's also an excellent choice for Smart India Hackathon hardware prototypes that need a light-following proof-of-concept.
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?
Scan the QR code on the box to launch the AI build companion, which walks you through each step. You can also chat with us on WhatsApp for direct help.
Can this kit really follow the sun, or is it just for a torch?
The quad-LDR array works with any directional light - sunlight, a table lamp, or a flashlight. It's designed to demonstrate the principle; attaching a larger solar panel is possible with external drivers.
Do I need any prior coding or electronics experience?
No. The included build guide starts from connecting wires to uploading pre-written Arduino code. You'll learn as you build and can modify the code later.
Is this kit suitable for a school science exhibition?
Absolutely. Many students have used this exact project in CBSE and ICSE exhibitions. It demonstrates real-time sensor feedback and closed-loop control, which earns top marks.
