A small and simple AM Radio project with only 2 transistors. Mediumwave stations cab be listened to in your area through this circuit. The variable capacitor (VC1) in parallel with the coil (L1) acts as a tunable resonant circuit. This {Read More}
In this article, we are going to show you how you can build a 5W stereo audio amplifier 5W using TEA 2025 IC. We have used two potentiometers for left and right volume controls. It has power output is {Read More}
Walkie Talkie using NRF24L01: Nowadays we are living in the area of 4G and 5G. Almost all devices enabled 4G or 5G. However, old technologies like walkie-talkie and RF communication are still using. In this modern age, Arduino based walkie-talkie {Read More}
In this article, we are going to explain the 1000W BT139 TRIAC light dimmer circuit by connecting the power line were a raised cardiac dimmer circuit triggered 500k can be adjusted by a potentiometer. It is a commonly used circuit that {Read More}
In simplest terms, a piezo buzzer is an electronic device that produces a tone, alarm, or sound. Piezo buzzer is like tiny little speakers, but unlike speakers, it does not require an amplifier or other circuit to drive. When voltage {Read More}
PC817 Optocoupler also called photocouplers & optoisolators, an IC kind of seeing tools available from 4 pins to many numbers of pins, they are commonly used for the separation of two circuits from each other. PC817 is a commonly used {Read More}
This article is about the infrared remote control switch by using simple components. This is simple and easy to make even one can design it at home with simple parts. The main part of this on/off switch circuit is IC {Read More}
A Logic gate is a circuit that has one or more input voltages however only one output voltage. logic gates are basic building blocks of the digital system.OR, NOT, & AND Gates are the fundamental kinds of gates. The interrelationship {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}
