This Project of control fans is used to control not only switching properties but also control speed of fan.
The main advantage of Clap Operated Fan Speed Control is, it can control up to ten-step speeds of fan.
Sound-operated trigger pulse : The MIC is used to change voice signal into its corresponding electrical signal…..
Clock pulse generator : This section timer 555 and configured as monostable multivibrator. The trigger pulse generated by MIC.
round decade counter which counts the clock pulse generated by timer IC.
Load operator:This section is build around three transistor as relay driver to operate three separate relay.
