Communication with the HMC5883L is simple and all done through an I2C interface. There is no on-board regulator, so a regulated voltage of 2.16-3.6VDC should be supplied. The Honeywell HMC5883L is a surface-mount, multi-chip module designed for low-field magnetic sensing with a digital interface for applications such as low-cost compassing and magnetometry. Applications for the HMC5883L include Mobile Phones, Netbooks, Consumer Electronics, Auto Navigation Systems, and Personal Navigation Devices.<\/p>\n<p><strong>DL2308Mk03<\/strong><\/p>\n<p>1 x Adafruit METRO M0 Express<br \/>\n1 x DS3231 Precision RTC FeatherWing<br \/>\n1 x SparkFun Triple Axis Accelerometer ADXL335<br \/>\n1 x SparkFun Triple Axis Magnetometer &#8211; HMC5883L<br \/>\n1 x Rocker Switch &#8211; SPST<br \/>\n1 x Resistor 10K Ohm<br \/>\n1 x CR1220 3V Lithium Coin Cell Battery<br \/>\n1 x SparkFun Cerberus USB Cable<\/p>\n<p><strong>Adafruit METRO M0 Express<\/strong><\/p>\n<p>LED &#8211; LED_BUILTIN<br \/>\nSDA &#8211; Digital 20<br \/>\nSCL &#8211; Digital 21<br \/>\nSW1 &#8211; Digital 2<br \/>\nACX &#8211; Analog A0<br \/>\nACY &#8211; Analog A1<br \/>\nACZ &#8211; Analog A2<br \/>\nVIN &#8211; +3.3V<br \/>\nGND &#8211; GND<\/p>\n<p>&#8212;&#8212;<\/p>\n<p><strong>DL2308Mk03p.ino<\/strong><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"arduino\" data-enlighter-title=\"\">\r\n\/****** Don Luc Electronics \u00a9 ******\r\nSoftware Version Information\r\nProject #28 - Sensors - Magnetometer HMC5883L - Mk02\r\n28-02\r\nDL2308Mk03p.ino\r\n1 x Adafruit METRO M0 Express\r\n1 x DS3231 Precision RTC FeatherWing\r\n1 x SparkFun Triple Axis Accelerometer ADXL335\r\n1 x Rocker Switch - SPST\r\n1 x Resistor 10K Ohm\r\n1 x CR1220 3V Lithium Coin Cell Battery\r\n1 x SparkFun Cerberus USB Cable\r\n*\/\r\n\r\n\/\/ Include the Library Code\r\n\/\/ DS3231 Precision RTC \r\n#include &lt;RTClib.h&gt;\r\n\/\/ Two Wire Interface (TWI\/I2C)\r\n#include &lt;Wire.h&gt;\r\n\/\/ Keyboard\r\n#include &lt;Keyboard.h&gt;\r\n\/\/ Triple Axis Magnetometer\r\n#include &lt;HMC5883L.h&gt;\r\n\r\n\/\/ Keyboard\r\nString sKeyboard = &quot;&quot;;\r\n\r\n\/\/ DS3231 Precision RTC \r\nRTC_DS3231 rtc;\r\nString dateRTC = &quot;&quot;;\r\nString timeRTC = &quot;&quot;;\r\n\r\n\/\/ Accelerometer\r\nint iX = A0;\r\nint iY = A1;\r\nint iZ = A2;\r\n\/\/ Accelerometer\r\nint X = 0;\r\nint Y = 0;\r\nint Z = 0;\r\n\r\n\/\/ Triple Axis Magnetometer\r\nHMC5883L compass;\r\n\/\/ Triple Axis Magnetometer\r\nint mX = 0;\r\nint mY = 0;\r\nint mZ = 0;\r\n\r\n\/\/ The number of the pushbutton pin\r\nint iButton = 2;\r\n\/\/ Variable for reading the pushbutton status\r\nint buttonState = 0;\r\n\r\n\/\/ Software Version Information\r\nString sver = &quot;28-02&quot;;\r\n\r\nvoid loop() {\r\n\r\n  \/\/ Date and Time RTC\r\n  isRTC ();\r\n\r\n  \/\/ Accelerometer\r\n  isAccelerometer();\r\n\r\n  \/\/ Magnetometer\r\n  isMagnetometer();\r\n\r\n  \/\/ Read the state of the button value:\r\n  buttonState = digitalRead(iButton);\r\n\r\n  \/\/ Check if the button is pressed.
