Abstract

Nowadays, the usage of digital tachometer is rare and revolution counter is non existent due to the fact that these electronic devices are quite expensive in the market. A digital tachometer and revolution counter will be displaying digitally the revolution per minute and total number of engine revolution of a car’s engine on the liquid crystal display. The digitally displays are more accurate and precise compared to analogue. A tachometer is a device that measures the rotation speed of a shaft in a car’s engine. A revolution counter concept is similar to an odometer where the revolution counter measures the rotation of crankshaft coverage while the odometer measures the distance coverage. The main objective of this project is to design and develop a low cost digital tachometer and revolution counter by using Microchip PIC microcontroller. A car maintenance schedule base on the total number of engine revolution will be proposed in this project as a reference for the driver to do his car maintenance. There are four phases of methodology to complete this project which are literature review, PIC source code development, hardware development and thesis writing. The expected result of this project is that, the circuit will be able to measure and display the revolution per minute readings and total number of engine revolution digitally on the liquid crystal display. Hopefully, this project can be implemented in our national automotive industry.
