Hacks of Electronics
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 […]
Field-Programmable Gate Arrays (FPGAs) might sound intimidating at first, but they’re actually one of the most exciting ways to learn digital design. Unlike microcontrollers (like Arduino or STM32) that run instructions on fixed hardware, FPGAs let you design your own hardware. That means you can create custom processors, signal processors, robotics controllers, or even video […]
Photodiode is a crucial component in modern electronics, enabling devices to detect and respond to light. From remote controls and light meters to solar panels and advanced optical communication systems, photodiodes play a silent but powerful role in shaping how we interact with technology. In this article, we’ll explore everything you need to know about […]
This article is on MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistor), covering the difference between D-MOSFET and E-MOSFETs with construction, working, advantages, disadvantages, and applications. MOSFETs are the most common types of Field Effect Transistors (FETs) in Modern electronics. It functions as a voltage-controlled device and delivers high input impedance along with fast switching speed. MOSFETs are the […]
A phototransistor is a semiconductor device that combines the properties of a photodiode and a transistor. It is sensitive to light and provides amplified electrical output based on the light intensity incident on its base region. Phototransistors play a vital role in optoelectronic applications such as light sensing, encoders, switches, and signal transmission, owing to […]
