Its output is given as a trigger to the first Its output is given as a trigger to the first monostable multivibrator NE 555.monostable multivibrator NE 555.

The output of decade counter is taken The output of decade counter is taken through Resistors R5 to R9 and capacitor C5 through Resistors R5 to R9 and capacitor C5 controls the pulse width which is actually controls the pulse width which is actually determining the speed of the fandetermining the speed of the fan

multivibrator is triggered by pulses multivibrator is triggered by pulses from opto coupler MCT2E.from opto coupler MCT2E.

The output from counter is given to The output from counter is given to NE555 and this is given to the NE555 and this is given to the transistor BC548transistor BC548

It is given to the Opto isolator MOC It is given to the Opto isolator MOC 3021. It is used for driving the Triac 3021. It is used for driving the Triac BT136BT136

control the pulse width. control the pulse width.

As the pulse width decreases firing angle of the As the pulse width decreases firing angle of the triac increases and speed of the fan also triac increases and speed of the fan also increasesincreases

remote controller controls the pulse width,which remote controller controls the pulse width,which in turn varies the firing angle of triac, and there in turn varies the firing angle of triac, and there by varying the speed of the fanby varying the speed of the fan
