Pulses from the IR receiver module are applied as a trigger signal to timer NE555 (IC1) via LED1 and resis- U tor R4. IC1 is wired as a monostable multivibrator to delay the clock given to decade counter-cum-driver IC CD4017 (IC2). Out of the ten outputs of decade counter IC2 (Q0 through Q9)‚ only five (Q0 through Q4) are used to control the fan. Q5 output is not used‚ while Q6 output is used to reset the counter. Another NE555 timer (IC3) is also wired as a monostable multivibrator. Combination of
