The Speed Meter finds out the velocity and acceleration of a moving vehicle using the GPS coordinates. The location coordinates are used to calculate the velocity and acceleration using predefined formulae. The results are sent to an Android application over Bluetooth to be displayed in real time using graphs. The application displays other results such as trip data, average speed and average acceleration as well.
