Create a Wearable Sedentary Alert with Arduino Nano: Vibrates Every 30 Minutes to Keep You Active

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Sitting for hours harms health, especially for young students and desk workers. This kit turns an Arduino Nano into a lightweight clip-on reminder that vibrates silently every 30 minutes, nudging you to stand up and move. The real magic: the same vibration motor doubles as a movement sensor, detecting when you actually get up and resetting the timer—no extra tilt switch required.

What You'll Build

You’ll assemble a compact, battery-powered wearable that attaches to your clothing or wrist. It keeps accurate time with the DS3231 real-time clock, triggers a discreet vibration alert on schedule, and then watches for your movement. Once you stand and start moving, the motor itself sends a tiny signal back to the Nano to reset the 30‑minute countdown.

What You'll Learn

• Program an Arduino Nano to work with a DS3231 real-time clock module
• Drive a coin vibration motor using a BC547 transistor switching circuit
• Use the motor’s back‑EMF as a movement detection signal (sensor‑less trick)
• Build a wearable prototype on a breadboard and power it from a 9V battery
