Build a Precise Pendulum Clock with OLED Display — Arduino and Stepper Motor 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.

Create a mesmerizing pendulum clock that combines mechanical motion with electronic precision. The stepper motor swings the pendulum arm in a perfect 1-second rhythm, while the DS3231 real-time clock ensures the time display on the bright OLED screen stays accurate to within seconds per month. This isn't just a clock — it's a piece of kinetic art that teaches advanced timing and motor control.

What You'll Build

You'll assemble and program a fully functional pendulum clock. The finished project features a smoothly oscillating pendulum driven by a NEMA 17 stepper, regulated by the highly accurate DS3231 RTC. The 0.96-inch OLED shows the current time in large, clear digits, with minimal drift thanks to automatic correction from the RTC.

What You'll Learn

• Interface and calibrate a DS3231 RTC for precise timekeeping
• Control a stepper motor for smooth pendulum motion
• Program an OLED display for real-time data output
• Debug timing loops and integrate hardware interrupts
