-GPS was tested by taking the GPS module and walking around campus to map out accuracy and areas of the campus that gave us inaccurate readings. Once the nodes were setup for pathfinding, the calculations of the desired heading were tested against the heading given by the compass to verify the accuracy of both the calculated heading and the actual heading of the car.

 We tested each of the components individually before integrating each component.
 Once each of the systems were verified to be working correctly, we connected one system at a time. We did this to help us identify if there were any systems that caused problems when adding them to the PCB.
