ABSTRACT
A new cost effective, speed controlled method was introduced to change the
speed of fan and coolers automatically. The device here presented makes the fan run
at full speed then change the speed to medium and finally the fan or cooler will turn
off. The system consists of an astable multivibrator which adjusts the speed of the
circuit. It also consists of two counters which counts the output from the multivibrator
and a relay is used, which act as an electrical switch. From this product, we can
change the speed of fan and coolers automatically without doing any manual effort.
Thus it’s the main advantage of this project.
