Solar System Orrery Motor Kit with Arduino Uno + Stepper Motor
Build a Working Mechanical Solar System Orrery with Arduino & Stepper Motor
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 a miniature mechanical solar system on your desk, with planets orbiting at accurately scaled speeds. This kit lets you build that orrery using a precise stepper motor and Arduino control. Perfect for space science demonstrations, STEM fairs, and understanding planetary motion through hands-on construction.
What You'll Build
A motorized orrery with planetary arms driven by a NEMA 17 stepper, displaying relative orbital periods. The 0.96-inch OLED shows current planet and rotation speed, while tactile buttons let you pause, speed up, or reset the simulation. The mechanical assembly (arms and planet cutouts) can be crafted from materials like cardboard or 3D-printed using our provided templates.
What You'll Learn
- Stepper motor control using A4988 driver and Arduino Uno
- Programming Arduino for precise angular movement and timing
- Calculating gear ratios and step angles to simulate planetary orbits
- Reading button inputs to create interactive simulation modes

Who This Kit Is For
Ideal for CBSE Class 11-12 students exploring physics and electronics, B.Tech ECE/EEE undergraduates building lab projects, and participants in Smart India Hackathon or ATL Tinkering Lab challenges. It's also a perfect fit for space science clubs at IITs, NITs, and VIT seeking a hands-on demonstration of orbital mechanics.
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 kit includes a QR code to our AI build companion, trained on this exact project. You can also reach us on WhatsApp for real-time guidance.
Does it include the mechanical structure for the planets?
The kit focuses on the motor drive and control electronics. You can construct the mechanical arms and planet cutouts from cardboard, foam board, or 3D-printed parts — we provide a template and suggestions in the build guide.
How accurate are the planetary speeds?
The Arduino code scales orbital periods to make the inner planets visibly move within minutes, while Jupiter and Saturn take much longer. It's a visual demo, not an exact clockwork.
Can I program my own orbit patterns?
Yes, the Arduino code is open-source and fully modifiable. The AI companion can help you adjust speed ratios or add new planets.
