Wearable Panic Button GPS Tracker Kit with Arduino Nano + LED
Build a Wearable Panic Button GPS Tracker with Arduino Nano — Instant SOS with Live Location
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 lets you create a compact wrist-worn device that, with a single button press, fires an SMS alert containing a live Google Maps link of your exact location. Whether you’re designing a personal safety solution for late-night campus commutes, a senior-care alert system, or a Smart India Hackathon prototype, the Wearable Panic Button GPS Tracker delivers real-time security in a build-it-yourself format. The integration of Arduino Nano, NEO-6M GPS, and SIM800L GSM module teaches advanced embedded skills while solving a pressing everyday problem.
What You'll Build
You will assemble and code a complete wearable unit fitted into a Velcro wristband. A tactile button mounted on the strap activates two high-brightness red LEDs for visual confirmation, while the microcontroller instantly reads GPS coordinates from the NEO-6M module and formats an SOS message. Within seconds, the SIM800L sends that message — with latitude, longitude, and a Google Maps pin — to a pre-programmed emergency contact. You’ll learn to manage a LiPo battery through a buck converter and TP4056 charging circuit, making the device truly portable.
What You'll Learn
- Interfacing the NEO-6M GPS module to parse NMEA sentences and extract real-time coordinates
- Establishing AT command communication with SIM800L to send SMS from an Arduino Nano
- Designing a stable wearable power system using an LM2596 buck converter, LiPo battery, and decoupling capacitors for reduced GSM spikes
- Soldering and assembling components onto a PCB prototype board within a fabric wristband enclosure

Who This Kit Is For
This advanced kit is built for B.Tech ECE/EEE students tackling embedded systems and IoT courses, especially those participating in Smart India Hackathon or BITS Pilani/VIT/NIT projects focused on women’s safety or assistive technology. ATL Tinkering Lab mentors will find it a powerful challenge for senior students moving beyond basic Arduino projects. It’s also ideal for security-conscious makers prototyping a real-world wearable alert system.
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?
Scan the QR code inside the box to open the AI companion, which offers step-by-step debugging and code verification. You can also message us on WhatsApp for direct guidance from our team.
Can I customize the emergency message or add multiple recipients?
Yes, the provided Arduino code is modular. You can edit the SMS text to include a name, medical info, or alternate contact numbers by modifying the AT command string and storing multiple numbers in the sketch.
Will the SIM800L module work with my existing 2G SIM card in India?
Airtel and Vodafone Idea still operate 2G networks in most areas, which the SIM800L requires. Insert a nano/micro SIM with an active 2G data plan, and the module will register on the network for SMS sending.
What if I want to extend the tracker to record location data on an SD card?
The kit provides a solid foundation; you can add an SPI microSD module to log coordinates periodically. The circuit design already includes spare prototyping area and decoupling caps to support expansion.
Button on wristband sends SOS SMS with live NEO-6M GPS coordinates via SIM800L on single press.
