Material ownership is that which is tangible (touchable), like property, a car, a book, etc. Immaterial ownership defines intangibles like copyright, trademark, patent, etc. Different kinds … Read more
In this article, we are going to make an automatic street light circuit. You must want to know how the streetlights turn on automatically in the evening and off in the morning. We want to tell you that nobody manually turns these lights on or off physically. In this article, we are describing a circuit … Read more
In this project I am going to show a very useful and beautiful flip flop circuit using timer IC 555. The circuit is able to blink 8 super bright blue and red LEDs. The circuit is built around a famous 555 timer IC, which is wired as an astable multivibrator here. The LEDs are classified … Read more
The 2N3904 is basically an NPN transistor made up of silicon material. It is used for a general-purpose switch and amplifier. It supports the current up to 100 mA when acting as a switch, and it supports the frequency up to 100 MHz while acting as an amplifier. 2N2222A is also an NPN transistor and … Read more
It is a small high-voltage shock circuit, with pressure from the low current. It is best for fun play. In-circuit has a few tools. just 2 small NPN transistors, 2 resistors, and 1 transformer. So easy to make and cheap. Pin detail of a small high-voltage shock circuit: When switch S1 closes, the circuit for … Read more
In this article we are going to explain different types of input devices. An input device is a special type of peripheral device that allows communication along with the processing unit of the computer system. A computer’s input devices are mostly to be used for recognizing the input data that are provided by users for solving their … Read more
An LED (Light Emitting Diode) is a semiconductor tool that emits light due to the electroluminescence effect. A light-emitting diode is mainly a PN junction diode, which emits light whenever forward biased. Light-emitting diodes are almost everywhere. You can find LEDs in cars, mobile phones, televisions, bikes, office lighting, street lights, home lighting, and many … Read more
LiFi Data Transfer System: A visible light communication system transmitting wireless internet communications is a visible light communication system that transmits data at very high speeds. This technology makes an LED light bulb transmit pulses of light that are unseeable by the human eye, and within those emitted pulses, data can travel in both directions. … Read more
The water level indicator is a system that gets information about the water level in tanks, which is used in homes and public places. We can control the overflow of water tanks by using the tank level indicator. As everybody knows, when the water is stored in the tank, nobody can identify the actual level of water … Read more
