Learn to build a GPS data logging system using a Raspberry Pi Pico W and Adafruit Ultimate GPS module in this 39-minute tutorial. Discover how to create a GPS tracker that measures and displays your current position, then logs GPS data to the Pico's flash memory with button-controlled start and stop functionality. Master the programming techniques for implementing a toggle system where pressing a button initiates data logging mode and pressing it again returns to standard measurement mode. Explore the hardware setup including the Raspberry Pi Pico W, Adafruit Ultimate GPS module, optional external antenna, and button battery for faster GPS fixes. Gain practical experience with GPS data handling, file logging operations on microcontroller flash memory, and user interface design for embedded systems. Follow along with detailed explanations of the code structure, data logging protocols, and best practices for GPS tracking applications on microcontroller platforms.
