Learn how to create an ESP32-based compass using a GY-271 magnetic sensor module in this hands-on tutorial. Begin by soldering pins onto the sensor board and wiring it to the ESP32 development board along with a 240x240 TFT LCD display and a 4x20 LCD module. Set up the project in VSCode with PlatformIO, install necessary libraries, and overcome initial challenges. Test the sensor using provided examples, then add LCD functionality to display XYZ coordinates. Implement a rotating gauge design inspired by Volos Projects for a visually appealing compass interface. Follow along as the project evolves from basic sensor readings to a fully functional, standalone compass with an attractive GUI. Gain practical experience in working with magnetic sensors, display modules, and ESP32 programming while creating a useful navigation tool.
