In modern electronics, signal isolation between different parts of a circuit is crucial for protection, noise reduction, and system stability. Optocouplers, also known as optoisolators, play a vital role in achieving this electrical isolation while allowing signal transmission. This article provides a thorough exploration of optocouplers (Optoisolator / Photocoupler), including their construction, working principles, advantages, […]
We see numbers displayed on many electronic devices around us, like digital clocks, calculators, microwave ovens, and scoreboards. But have you ever wondered how these numbers appear on the screen? One of the most common ways to show numbers in electronic devices is by using a Seven Segment Display. It is a simple electronic component […]
In the field of electronics and optoelectronics, light-sensitive devices play a crucial role in converting light signals into electrical signals. Among the most widely used light sensors are the Photodiode, Phototransistor, and Photoresistor (also known as Light Dependent Resistor or LDR). Though they all respond to light, their construction, working principles, advantages, disadvantages, and applications […]
Photodiode is a crucial component in modern electronics, enabling devices to detect and respond to light.
