5Micro controller based tachometer6 design makes use of 78,1 micro

controller for interfacing to #arious hardware peripherals. *echnology today is

seeing its heights in all the areas0 especially in the area of %mbedded "ystems. It is

true that e#ery electronic gadget that is used in daily life right from a PC keyboard

to be frigerator is an %mbedded "ystem. *his itself shows how #astly the

technology is e&panding .*he current design is an embedded application which is

used to calculate the speed of the motor without the need of tachometer. In this

application I fre3uencies are used to calculate the speed of the motor.

Photoelectric tachometer measures the rpm of most shop9floor tools and manyhousehold machines without any mechanical or electrical interface by making use

of 78,1 microcontroller. *achometer is nothing but a simple electronic digital

transducer. 4ormally0 it is used for measuring the speed of a rotating shaft. *he

number of re#olutions per minute :rpm; is #aluable information for understanding

any rotational system.
