Mircemk has developed a digital compass utilizing a HMC5883L magnetometer, an Arduino Nano, WS2812B LEDs, and a small OLED display. Traditionally, magnetic compasses have been relied upon for navigation, and this project showcases the capabilities of modern digital magnetometers. The HMC5883L magnetometer detects magnetic fields in three axes, with the Arduino Nano processing the data to indicate the bearing of magnetic north. The compass’s output is represented through a string of WS2812B LEDs, while an OLED display provides information about the angle between the compass arrow and magnetic north. This creation serves as both a functional device and an educational tool for learning electronics and navigation concepts.
By creatively combining modern technology with a classic navigational tool, Mircemk has successfully built a compact digital compass. The project’s core component, the HMC5883L magnetometer, detects magnetic fields and facilitates the calculation of magnetic north bearing. An Arduino Nano processes the magnetometer’s output, enabling the WS2812B LEDs to display the magnetic north direction, and the small OLED display to showcase the angle between the compass arrow and magnetic north. This project is a testament to the fusion of traditional navigation with contemporary electronics, making it a valuable educational tool while also retaining practical functionality.
