Stepper Motor Analyser Kit with Arduino Uno + Stepper Motor
Diagnose and Understand Every Stepper Motor with This Arduino-Powered Analyser 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.
Turn your curiosity about stepper motor health into a hands-on diagnostic tool. This kit guides you in building an analyser that reads NEMA17 coil resistance, captures back-EMF on each phase, and cycles the A4988 driver through all microstepping resolutions—giving you a deep, practical understanding of how these ubiquitous motors actually perform.
What You'll Build
You'll assemble a compact, breadboard-based instrument with an OLED display that walks you through each test. The analyser automatically measures resistance in both coils, runs the motor at different speeds to sample back-EMF, and then sweeps the A4988 from full-step to 1/16-step, graphing current behaviour live. The result is a portable stepper motor health checker you can use for robotics maintenance, lab experiments, or troubleshooting motor-driven prototypes.
What You'll Learn
- Measure low-resistance windings accurately using an Arduino and ACS712 current sensor
- Sample and interpret back-EMF waveforms to detect phase imbalances
- Control the A4988 stepper driver programmatically across all microstepping modes
- Display real-time sensor data on a 0.96-inch OLED and build a simple UI

Who This Kit Is For
This kit fits naturally into CBSE Class 11–12 Physics practicals where electromagnetism and motor characteristics appear, and into B.Tech ECE/EEE labs covering actuator diagnostics. Students preparing for Smart India Hackathon hardware tracks will find the analyser invaluable for characterising donated or salvaged stepper motors. ATL Tinkering Labs and makerspaces at IIT/NIT/VIT/BITS Pilani can use it as a self-contained instrument to teach motor control fundamentals without an oscilloscope.
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 inside the box to launch the AI companion trained on this kit; it provides step-by-step debugging. You can also reach us on WhatsApp for direct help from our engineers.
Can this analyser test NEMA23 or other stepper motors?
The included NEMA17 is a reference motor. You can connect other bipolar steppers with similar current ratings by switching the coil wires; the code and sensor range are optimised for NEMA17-like windings under 5A.
Is any soldering required?
No. All connections are made on the 400-point breadboard using the pre-cut jumper wires. The OLED and sensor modules have pin headers that plug directly into the board.
How accurate are the resistance and back-EMF readings?
The kit uses a simple constant-current approach that achieves ±5% accuracy when compared to a lab DMM—more than enough for educational diagnostics and quick motor health checks. The AI companion explains calibration steps if you need tighter tolerance.
