Learn to calibrate a 3-axis magnetometer and build a digital compass using the Arduino Uno R4 WiFi and GY-87 module in this comprehensive 58-minute tutorial. Master the process of obtaining readings from the QMC5883L 3-axis magnetometer, which measures magnetic field strength in x, y, and z directions. Discover essential calibration techniques to ensure accurate measurements and calculate yaw or heading values to determine directional orientation. Follow along as you transform raw magnetometer data into a functional digital compass that displays the precise direction your device is pointing. Gain hands-on experience with magnetic field sensing, data processing, and compass implementation while working with the GY-87 sensor module and Arduino programming environment.
