Module for Digital Compass for Arduino
Introduction
Several people develop projects with robotics and one of the big problems is determining their navigation direction. In other words, the robot moves around the environment, but the system does not know its exact direction and this implies the process of its navigation.
As a solution, many people adopt the use of the GPS device to assist in the process of determining the direction. However, due to its commercial financial value, the project becomes more expensive and makes it impossible to use it to determine only the navigation direction.
In this case, the ideal is to use a magnetometer sensor. It has the ability to determine the direction of guidance from low financial investment in the project. That way, you will be able to determine your robot's navigation direction.
In this article, you will learn how to build your own digital compass with Arduino. Through it, you will be able to learn the complete operation of the HMC5883L sensor, to detect its orientation direction.
In addition, you will learn how to build your own electronic compass board and use it with your Arduino. In Figure 1 is shown the printed circuit board of the digital compassing.
Figure 1 - Printed Circuit Board of the Digital Compassing.
Therefore, at the end of the article you will have learned the following points:
- Creation of a digital compass with Arduino;
- Operation of the HMC5883L sensor;
- Creation of the Compass Printed Circuit Board with Arduino;
- Win the Compass printed circuit board files with Arduino.
