Hacks of Electronics
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 […]
An Astable Multivibrator is an essential oscillator circuit in electronics, used to generate continuous square wave signals without any external triggering. It is called “astable” because it has no stable state — both transistors in the circuit keep switching ON and OFF alternately, producing a continuous flip-flop output. In this article, we will explore a […]
Explore Universal NAND Gate from its truth table to its IC pin diagram, delve into transistor-based logic circuit construction and working, and discuss the advantages, disadvantages, and various applications of the NAND gate. Just as the NOR gate combines the OR and NOT functions to provide an inverted output when all inputs are low, the […]
While they may seem like two sides of the same coin, encoders and decoders serve opposite but equally crucial roles. In this article, we’ll learn about difference between encoder and decoder with their types, pros and cons, real-world applications, and some of the most commonly used encoder and decoder ICs. In the world of digital […]
