NEW Tutorial – Adafruit HMC5883L Breakout – Triple-Axis Magnetometer/Compass Sensor @ Adafruit Learning System. How to get started and calculate heading with the HMC5883 breakout from Adafruit.
He told you “Go West, young maker!” – but you don’t know which way is West! Ah, if only you had this triple-axis magnetometer compass module. A magnetometer can sense where the strongest magnetic force is coming from, generally used to detect magnetic north.
We based this breakout on a popular and well loved magnetometer, the HMC5883L. This compact sensor uses I2C to communicate and its very easy to use. Since it’s a 3.3V max chip, we added circuitry to make it 5V-safe logic and power, for easy use with either 3 or 5V microcomtrollers. Simply connect VCC to +3-5V and ground to ground. Then read data from the I2C clock and data pins.
