Stepper Motor Desk Watch – Arduino Nano Clock Project with Microstepping

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 turns a NEMA 17 stepper motor into the heart of a miniature clock. A DS3231 real-time clock feeds accurate time to an Arduino Nano, which drives the stepper through an A4988 driver in microstepping mode. The result is a silent, continuous-sweep hand that advances 3600 times per hour – no tick marks, just one smooth arc. You’ll solder the circuit, fit it inside a laser-cut wooden frame, and watch time glide.

What You'll Build

A fully functional analog desk clock with a single sweeping hand, visible through the wooden case. The 0.96-inch OLED shows time and diagnostic info like motor steps, while the DS3231 keeps it accurate for months. The stepper motor moves with 1/16 microstepping, giving 3600 distinct positions per full revolution of the clock hand. Power comes from a 12V adapter, and everything fits inside a compact wooden enclosure you assemble yourself.

What You'll Learn

• Program an Arduino Nano to read the DS3231 RTC over I2C and update the OLED display in real time.
• Configure an A4988 stepper driver for microstepping, current limiting, and smooth acceleration.
• Solder through‑hole components and headers onto prototype boards to create a permanent, robust circuit.
• Combine timekeeping logic with motor control to build a sweep-motion clock that never stalls.

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11–12 students diving into embedded systems, first‑year B.Tech ECE/EEE learners, and ATL Tinkering Lab members will find this kit a natural fit. It’s also ideal for hobbyists who want a unique mechanical clock on their desk and for Smart India Hackathon participants prototyping precision motor control. The soldering step gives it a hardware depth beyond a breadboard project, making it a clear step up in skill.
