Automation is also now playing wide role in the field of automobile design and to provide the vehicle management system with automatic units so the user has simplicity to use it. This project is also concerned with design of automatic unit to calculate the speed and distance covered by the vehicle.
A speedometer is a gauge that measures and displays the instantaneous speed of a land vehicle. An odometer is an instrument that indicates distance traveled by a vehicle, such as a bicycle or automobile. The device may be electronic, mechanical, or a combination of the two.
This kit is basically dependant of programming for interrupt. The IR sensor provides the interrupt signal which initiates a timer and using this feature we calculate the speed. Using the speed we can calculate the distance also.
