Abstract
The purpose of this paper is to explain how to build a digital compass and program the pic16f72 microchip, which will result in a fully functional directional compass. Additionally, I will discuss how I then modified the circuit board, as well as the software, in order for the digital compass to display arrows that point North when rotated in every direction.

Introduction
The compass kit used in this project was ordered through the DeVry bookstore: 32DVRCOMPASSR1. The heart of this project is the Dinsmore 1490 sensor compass module. When rotated, it displays the position of the four cardinal points on the compass: N, S, E, and W as well as the intermediate directions: NE, NW, SE, and SW. The signal from the module is controlled by the program in
