The system includes a DC-DC converter circuit and control logic to operate a DC motor and display relevant information on an I2C LCD. A push button triggers the system, turning on a red LED and ...

The Joule Thief Circuit is a simple and clever electronic design that can power an LED using a nearly dead battery. The project demonstrates how basic components like a transistor, a toroidal coil, ...

Nowadays, many people are turning towards green solutions to lead healthier lives. Efforts are being made to grow plants, which contribute to maintaining the stability of nature. The key challenge in ...

This is a simple FM Radio Receiver that is built around a single IC1 AN7236 (18-pin), a single HF transistor Q1( BF 494) and a few external components. This FM radio can be tuned for frequencies ...

This simple micro ampere meter circuit can help in measuring small currents in five ranges: from 1 µA to 10 mA. The meter is working in this way: the current being measured Ix shifts the input voltage ...

The design of the project consists of a few simple electronic components to create a metronome device that can be used as an invaluable practice tool for musicians. The term metronome refers to ay ...

Each LED is connected to one of the Arduino's digital output pins through a 220Ω resistor. A push button is connected to each input pin and uses the internal pull-up resistor feature of the Arduino.

It's really surprising: it turns out that among simple electronic circuits, built of just a few components, many of them behave chaotically, in an extremely complicated, practically unpredictable ...
