The circuit presented here is that of a digital fan regulator, variable to provide five speeds levels as catered for in ordinary fan regulators. The circuit makes use of easily available components. An optional 7-segment display with its associated circuitry has been provided to display your choice of fan speed. In future aspect, adding an IR system will improve the system so the speed change technique will be precised & accurate.
The heart of the circuit is a module-6 binary counter, built around IC2 and IC3 (IC 74LS76) which is dual JK flip-flops. The counter counts up in a straight binary progression from 000 to 101 (i.e. from 0 to 5) upon each successive clock edge and is reset to 000 upon next clock. The report consist of Circuit diagram, block diagram, PCB layout and complete working of the project.
Abstract:
Digital (Fan) Regulator is one of the applications of electronics to increase the facilities of life. Fan is one of the unavoidable Electronic equipment in our day to day life. It has become essential element without which people can’t lead a smooth life. The presence of a fan in a house or office is not now considered as a luxury on the other hand it is included in the basic requirement. The uses of new electronic theories have been put down by expertise to increase the facilities given by the existing appliance. Here the facility of ordinary fan is increased by the making its speed digitally displayed.
In digital fan regulator we can regulate the speed of the fan by using tactile button. Here the variation in the square wave counts of IC (NE555) is used for regulating the speed.
A Tactile button can be used for controlling speed of the fan. Using this circuit, we can change the speed of the fan. This circuit is used for controlling the speed of the fan in 5 levels. This innovation can be a success only if people are made aware about its advantages and how user-friendly it is. The circuit can be used to regulate the intensity of light, maintain the change of accuracy.This innovation finds its use mainly to help the industry where accuracy is needed in every moment.
So this topic was chosen for the necessity of regulation and the concept is based on the basic regulation prototype was thought in mind and the concept of doing this project was undertaken.
