Clap worked Remote Control for Fans

Clap  worked Remote Control for Fans
Here is the circuit of applaud worked remote control fans is utilized to control not just exchanging properties additionally control speed of fan. The fundamental favorable position of applaud worked remote control for fan is, it can control up to ten-stage velocities of fan where ordinarily a fan has three to five stage speeds. Circuit depiction applaud worked remote control for fan This whole circuit applaud worked remote control for fan is partitioned into four noteworthy segment i.e. sound-worked trigger heartbeat generator, clock beat generator, clock beat counter and load administrator. Sound-worked trigger heartbeat.

The heart of this area is transistor T1 BC148, arranged as class-C speaker mode. The MIC1 is utilized to change voice motion into its comparing electrical flag and is given to base of transistor T1 so as to intensify and increment its power. Clock beat generator:- This segment is work around clock IC NE555 and designed as monostable multivibrator. The trigger heartbeat created by transistor T1 is given to stick 2 of IC1 what's more, day and age (T) for yield high is figured by recipe. T = 1.1RC Clock Pulse counter:- This area is work around decade counter CD4017BC which checks the clock beat produced by clock IC (IC1). The yield from IC1 is given to stick 14 of IC2. IC2 has ten yields, viz, o, 1, 2, 3, 4… ..9. Here we utilize just three yields i.e. yield 1, 2 and 3 from stick 2, 4, and 7 separately. Yield 4 from stick 10 is straightforwardly associated with reset stick 15. Stack administrator:- This segment is work around three transistor as hand-off driver to work three isolate hand-off. Yield from every stick of IC2 is given to base of every transistor through 100ω and Driven as appeared in circuit graph. Yield is taken from authority of transistor and is associated with transfer. The three LEDs used to show rigging or speed i.e. LED1, LED2 and LED3 shows outfit 1, equip 2 and apparatus 3 individually. 

Resistors (all ¼-watt, ± 5% Carbon) R1 = 10 Kω; R2 = 1.2 Mω; R3 = 2.2 Kω; R4 = 150 Kω; R5 = 220 Kω; R6 = 10 Kω; R7, R8, R9 = 100 Ω
Capacitors C1, C2 = 0.1 μF/16V; C3 = 4.7 μF/16V; C4 = 0.01 μF (fired circle); C5 = 1000 μF/12V Semiconductors
IC1 = NE555 (Timer IC); IC2 = CD4017BE (decade counter); T1 = BC148; T2, T3, T4 = BEL187; D1, D2 = 1N4001 silicon diode Incidental MIC1 = Condenser receiver 34LOD; LED1 = Green; LED2 = yellow; LED3 = RED 6V-0V-6V, 500mA optional transformer.
