Pin-1, GROUND: It is the GROUND PIN of the IC. The negative terminal of DC power supply or battery is connected to this pin. Here note that…

Security alarm using IC 555

We know that when pin-4 is connected to positive potential, the IC works in normal condition, but whenever, the pin-4 is connected to ground, it overrides all functions of the IC and the output of the IC remains LOW. This facility is used in the following circuit to design a simple security system. Circuit diagram…

Simple Tutorials: Complete Working of NPN Transistor

Brief Introduction Transistor is a semiconductor device having three layers, three terminals and two junctions. Since we have only two types of semiconductors i.e. the p-type and n-type, there are two types of transistors: they are NPN transistor and PNP transistor. It is named as transistor which is an acronym of two terms: “transfer-of-resistor.” It…
