GPS Compass/Magnetometer HMC5883L Problems with Arduino

[Daniel Alivov]

Hello everybody, I hope all is well. I am currently building a robotic car which is GPS Guided and Bluetooth Controlled, using the Arduino Mega 2560 microcontroller and HMC5883L compass. I have run into a problem while calibrating the compass, I cannot get data (or X Y coordinates) from the Serial Monitor. The Monitor is at 9600 baud, Newline, I have checked the wiring of this compass, and am using non-magnetic header pins (although this only affects the accuracy of data). For those with experience with the GPS projects and HMC5883L compass, I would appreciate your help.

Hi Daniel

For questions about the Serial Monitor, best to ask on the Arduino forum: https://forum.arduino.cc
