Precision Linear Positioner Kit with Arduino Uno + Stepper Motor
Precision Linear Positioner Kit: Arduino Uno + Stepper Motor with AS5600 Encoder for Absolute Position Feedback and OLED Rotation Logging
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Step into industrial automation by building a closed-loop positioner that reads absolute rotor angle with a magnetic encoder, displays real-time data on an OLED, and logs every rotation to EEPROM. This kit transforms a standard stepper motor into a precision feedback system — the same principle used in CNC machines and robotic arms. You’ll wire, code, and test a complete motion control loop that a B.Tech student or hobbyist can complete in an afternoon.
What You'll Build
You’ll assemble a system where the AS5600 magnetic encoder tracks the shaft of a NEMA 17 stepper motor with 12-bit accuracy, sending angle data over I2C to an Arduino Uno. The OLED shows the current angle, and the firmware logs total revolutions into onboard EEPROM, preserving counts even after power-off. The result is a working linear positioner brain — you can later mount it on any linear rail to create a physical stage.
What You'll Learn
- Read absolute angular position from a magnetic encoder via I2C
- Control a stepper motor with microstepping using the A4988 driver
- Log rotation data to Arduino EEPROM for persistent storage
- Understand closed-loop feedback logic in real-world automation

Who This Kit Is For
Built for CBSE Class 11–12 students stepping into automation, first-year B.Tech ECE/EEE explorers, and Smart India Hackathon participants who need a dependable feedback-control demo. It also fits well into ATL Tinkering Lab sessions at schools and DIY corners of IIT, NIT, VIT, or BITS campuses.
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?
Open the AI companion through the QR code or send a WhatsApp message describing where you’re stuck. The guidance is based on the actual kit wiring and firmware, so you’ll get context-specific help.
Do I need an actual linear stage to test the positioner?
No, the kit focuses on the electronics and firmware. You can test the complete closed-loop logic using just the motor shaft and the encoder magnet, and later integrate it with any mechanical rail or lead screw.
Will the logged rotation data survive power loss?
Yes, the Arduino’s onboard EEPROM stores the total revolution count, so the tracking resumes correctly after a power cycle — just like an industrial encoder memory.
Is this kit suitable for a school exhibition project?
Absolutely. The OLED display shows live angle data, and you can demonstrate auto-homing, angular positioning, or rotation logging, making it a compelling and visual STEM exhibit.
Industrial Automation — AS5600 magnetic encoder reads absolute rotor position. OLED shows angle and logs rotations to EEPROM.
