Building a powerful yet compact audio amplifier can greatly enhance your audio experience. This article details how to construct a 3-channel TDA2030 amplifier circuit with separate left, right, and bass channels, powered by a dual ±12V supply. Additionally, it integrates a bass filter circuit, Bluetooth support via a 7805 regulator, and multiple protection features to […]
A Regulated Power Supply Block Diagram represents the working principle of a linear regulated power supply, which provides a stable DC output voltage. Unlike switching power supplies, linear regulators use transformers, rectifiers, and voltage regulators to ensure smooth voltage. A Linear Regulated Power Supply Circuit Diagram illustrates its detailed design. These power supplies are preferred […]
Air pollution has become a critical issue in modern society, affecting human health and the environment. Monitoring air quality is essential for creating a healthier living environment. With advancements in IoT (Internet of Things) technology, real-time air quality monitoring has become more accessible and efficient. In this project, we will build an IoT-Based Air Quality […]
Most electronics projects are characterized by breadboards, jumper wires, ICs, power supplies, and several other discrete components, such as resistors, transistors, and capacitors. But are wiring harnesses necessary? Cable assemblies are not really necessary in such projects because all you need are jumper wires. However, they provide several benefits, which I’ll explain below to justify […]
Weather monitoring is essential for various applications, from agriculture to home automation. The Arduino-based Weather Station using the BME680 sensor allows users to measure temperature, humidity, pressure, and gas resistance. The data will be displayed on an I2C LCD screen in cyclical manner, also it calculates Dew Point using Magnus formula and Altitude from pressure. […]
