Nano Pendulum Clock Escapement Kit with Arduino Nano + Sensor
Build a Real Working Pendulum Clock with Arduino Nano and Hall Sensor Escapement
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 pendulum that never stops swinging — not by magic, but by clever electronics that detect its motion and give it a tiny, precise nudge at exactly the right moment. This kit replaces the traditional mechanical escapement of a clock with an Arduino Nano, a Hall sensor, and a servo motor, creating a fascinating fusion of physics and coding that tells accurate time on a bright OLED display.
What You'll Build
You'll assemble a self‑sustaining pendulum clock that counts each swing via a magnetic Hall sensor placed near the bob. The Arduino Nano reads this signal and commands the SG90 servo to deliver a calibrated push, maintaining perpetual oscillation. The DS3231 RTC provides tenacious timekeeping, and the 0.96-inch OLED shows hours, minutes, and seconds — a fully functional clock born from a handful of components.
What You'll Learn
- Detect magnetic fields and pendulum position with an A3144 Hall sensor
- Program a servo motor to execute precise angular nudges on command
- Interface a DS3231 real‑time clock module for rock‑solid timekeeping
- Implement a closed‑loop control algorithm that keeps the pendulum swinging indefinitely

Who This Kit Is For
Young makers aged 5‑15 (with adult guidance) will love seeing physics come alive through a real escapement. It’s a standout project for ATL Tinkering Labs, CBSE school exhibitions, and budding electronics hobbyists across India who want to move beyond blinking LEDs and build something that ticks with purpose.
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 AI companion, trained on every step of this clock project, will diagnose your issue instantly. You can also message us on WhatsApp for a quick reply from a real builder.
Does this kit require soldering?
Yes, a soldering iron and solder wire are included because you’ll need to solder header pins onto the Nano and mount components on the PCB prototype board. It’s a perfect first soldering experience.
Can the clock run without the DS3231 RTC module?
Technically yes, but you’d lose accurate timekeeping. The RTC keeps track of actual time even when the pendulum pauses; without it, the clock would just be an oscillator with no real‑world time reference.
Is the Arduino Nano pre‑programmed with the clock code?
No, you’ll upload the code yourself using the Arduino IDE. This gives you full control to tweak the servo push strength, sensor sensitivity, and even add chimes — turning it into a true coding learning experience.
Hall sensor on pendulum counts swings. Servo nudges pendulum. Nano keeps pendulum swinging as clock.
