Hacks of Electronics
Modern electronic systems rely heavily on both digital and analog signals. While microcontrollers, computers, and digital processors handle data in binary (digital form), most real-world signals such as sound, temperature, pressure, and voltage are analog. To bridge this gap, Digital to Analog Converters (DACs) are used. A DAC takes digital input (binary numbers) and converts […]
In today’s world, most electronic devices operate digitally, but the signals we experience in the real world—such as sound, light, temperature, and pressure—are analog in nature. To process these signals in microcontrollers, digital signal processors (DSPs), or computers, we need to convert analog signals into digital form. This is where an Analog-to-Digital Converter (ADC) comes […]
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 […]
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 […]
Data transmission is the fundamental process of transferring digital or analog data between two devices. It plays a vital role in telecommunications, networking, computer architecture, and embedded systems. Two primary methods of data transmission are Synchronous and Asynchronous Transmission. Understanding their differences, working principles, and applications is crucial for designing efficient communication systems. Table of […]
