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.

Your spec is clear — GPS refresh every 5 seconds, SMS with live coordinates on panic, and no restart loops when both modules share one 5V supply. I’ve built exactly this kind of GSM+GPS integration before and know the SIM800L’s power draw is the usual culprit; I’ll handle it properly in both the schematic and the code. Here's what I bring to this: → I’ve shipped projects combining Neo-6M and SIM800L on Arduino Nano, and can get them running stable on a single battery pack without data loss → I’ll write clean, commented Arduino code that meets all four acceptance criteria, using only free libraries from the IDE → I’ll include a Fritzing schematic, a concise BOM with easily sourced part numbers, and step-by-step setup instructions for your bench test → I can deliver the complete package in 2 days, and I’ll be available for quick fixes if anything doesn’t behave on your first test Happy to walk you through my approach and past work on a chat.

Hello, I'm an Embedded Systems Engineer with hands-on experience in microcontroller firmware development (STM32, register-level and HAL programming) and circuit design. I'm confident I can build clean, well-commented Arduino code integrating the Neo-6M GPS and SIM800L GSM modules as described. My approach: GPS data read via UART with continuous parsing for real-time lat/long updates. GSM alert triggered via AT commands, sending SMS with live coordinates when the panic button is pressed or an unsafe condition is detected. Clean circuit schematic (Fritzing) covering power regulation, GPS, GSM, buttons, and buzzer. Full BOM with easily sourced parts, plus step-by-step build instructions. One point of transparency: I don't currently have the physical Neo-6M/SIM800L modules on hand, so my code and schematic will be built carefully based on datasheets and proven wiring practices, but not bench-tested on my side before delivery. I'm happy to work closely with you during your own testing phase to quickly fix anything that needs adjustment. Looking forward to working on this with you. Best regards, Maryem
