A light-dependent resistor is also known as a photoresistor, photoconductor, and photocell. An LDR is one kind of resistor whose resistance differs depending on the amount of light falling on its surface. When the light falls on the resistor, then {Read More}
In this article, we are going to show you two way light switch. A 2-way switching means you can control operate appliances like bulb water pump etc by using two switches at different locations, generally used to control water pump {Read More}
A neon bulb contains neon gas at low pressure, enveloped in a glass capsule. Neon lamp Circuits emit light when electric light passes through the gas. These lamps widely used in neon signboards. The neon lamp is composed of a {Read More}
A capacitor is an electronic component distinguish by its capacity to store an electric charge. A capacitor is a passive electrical part which can store energy in the electric field between a pair of conductors (it is called “plates”). In {Read More}
The Diode is an electrical part that allows the flow of current only in one direction. In-circuit diagrams, a diode is represented by a triangle with a line across one peak. Pin configuration of the diode. In this article, we {Read More}
The 2SA1943 transistor is a PNP transistor originally from Toshiba. Due to the transistor high current gain and collector current it is very generally used in AF amplifiers or High power audio circuits. But now this Transistor is entirely from {Read More}
The 2Sa1015 is PNP transistor which is mainly used for general purpose amplification. This transistor consists of three terminals: emitter, base and collector. N layer represents the base side and P layers represent emitter and collector. In the market 2sa1015-y, {Read More}
Doorbell Circuit using IC 555 and CD4017: The bell is a very common and useful electronic device used in houses, offices, etc. Among electronics students and hobbyists, the doorbell circuit project is very popular. So in this tutorial, I am {Read More}
BC549 transistor: This is an NPN transistor so the collector and emitter will be on when supply small current to base. BC549 is a low current transistor so the max amount of current that could flow through the Collector pin {Read More}
2n2907 transistor is PNP Bipolar transistor available in metal can package, having a high 600mA value of current with low voltage of 40v. Transistor 2N2907 being is fully biased when positive current is given to base. This transistor is having {Read More}
