Block Diagram Of Ic 555 Timer. As shown in figure ic555 includes two comparators one rs flip flop and other few discrete components like transistors resistors etc. The resistive network contains three equal resistors which will act as a voltage driver.
Now as shown in figure there are eight pins for a 555 timer ic namely 1 ground. The ic 555 uses three resisters of 5kω therefore the name is given as ic555. The working modes of a 555 timer are astable bistable and monostable.
Even make things simpler require more effort than making it complex.
Upper comparator has a threshold input pin 6 and a control input pin 5. The working modes of a 555 timer are astable bistable and monostable. From these 1 3 vcc is given to non inverting terminal of trigger comparator and 2 3 vcc is. I have made this circuit as simple as possible you can find many complex clap switches using 555 ic with some more components in it and merely doing the same thing.
