Abstract

This project is about digital tachometer. Tachometers are used to measure the velocity or speed of a rotating object in RPMs. Compares to analog system, digital is more accurate and easy to read the measurements as display on the screen. PIC microcontrollers from Microchip was use in this digital tachometer project. The main part of this project is encoding and decoding the digital signals. This problem makes it desirable to use a microprocessor, since the data registers can be use to store and parse the digital values at appropriate times. PIC16F877A has been chosen as a central processing unit in this project. This digital tachometer uses infra red sensors to detect the speed of motor and then the signal will be sent to the PIC. Next, the value will be display by 7 segments LED display. Using serial port connection, this tachometer can be connected to the computer and the value then can be display on the computer by Microsoft Visual Basic 6.0. At the end of this project, after implemented the hardware, the troubleshooting is the most important action that must be taken in order to achieve the objective of this project.
