Sedentary Time Vibration Alert Kit with Arduino Nano: A Wearable Buzz to Beat Prolonged Sitting

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 transforms an Arduino Nano, a DS3231 real-time clock, and a coin vibration motor into a wearable device that vibrates gently every 30 minutes, reminding the wearer—a child glued to screens or studies—to stand up and move. Tapping or shaking the device resets the timer, turning a simple circuit into an engaging health gadget that children build themselves. From understanding how an RTC keeps precise time to programming a motor-driven alert, every step builds real-world STEM skills while fighting sedentary habits common in Indian homes.

What You'll Build

A compact vibration alert module that can be slipped into a wristband or placed on a desk. It tracks time precisely using the DS3231 RTC and triggers the coin vibration motor through a BC547 transistor. The magic happens when the wearer shakes the device: the same motor acts as a sensor, generating a tiny voltage that the Arduino reads to reset the alert—no extra accelerometer needed. The result is a battery-powered, attention-grabbing nudge that makes standing up a fun, interactive habit.

What You'll Learn

• Interface a DS3231 real-time clock with Arduino Nano and read accurate time data.
• Drive a vibration motor safely using a BC547 transistor as a switch.
• Detect physical movement by reading the motor’s back-EMF as an analog signal.
• Write Arduino code for timed alerts, noise filtering, and reset logic.
