Smart Blind Stick with GPS

Descripción de la oferta
I’m building a smart blind stick powered by Arduino that combines GSM and GPS. The core goals are straightforward: give real-time location tracking through GPS navigation and trigger an emergency alert whenever the user presses a panic button or the stick detects an unsafe situation. The alert must be sent over GSM as an SMS that includes live coordinates so a caregiver can locate the user immediately. Here is what I need from you: • Complete, well-commented Arduino code that integrates a GPS module for continuous position updates and a GSM module for outbound SMS alerts. • Circuit schematic (Fritzing or similar) showing all connections—microcontroller, GPS, GSM, power regulation, and tactile buttons/buzzers. • A concise bill of materials with part numbers that are easily sourced online. • Step-by-step setup instructions so I can reproduce the build and test it on a real stick. Acceptance criteria 1. The serial monitor shows latitude/longitude refreshed at least once every 5 s. 2. Pressing the emergency button immediately dispatches an SMS containing the latest coordinates. 3. GPS and GSM modules coexist without data loss or restart loops when powered from a single 5 V battery pack. 4. Code compiles on the current Arduino IDE with no external paid libraries. If you already have experience blending Neo-6M, SIM800L (or equivalent) and an Arduino Uno/Nano, this will be a quick project. I’m happy to answer hardware questions during development and will test everything on my bench the moment you deliver.
