What is a Semiconductor? A semiconductor is a material that has electrical conductivity between that of an insulator and a conductor. Its ability to conduct electricity can be controlled through various means, such as doping, temperature, and exposure to light. This unique property makes semiconductors the foundation of modern electronics. […]

Introduction to PCB Milling PCB milling is a subtractive manufacturing process used in the fabrication of printed circuit boards (PCBs). It involves the use of a computer-controlled milling machine to remove unwanted copper from a pre-laminated PCB substrate, leaving behind the desired electrical circuit pattern. This process is an alternative […]

Introduction to USB Pinout USB (Universal Serial Bus) is a widely used interface standard for connecting various devices to computers, such as keyboards, mice, printers, and external storage devices. Understanding the USB pinout is crucial for anyone working with USB devices, whether you’re a hobbyist, a technician, or an engineer. […]

What are Zero-Crossing Detectors? Zero-crossing detectors are electronic circuits that detect the point at which an alternating current (AC) signal crosses the zero voltage level. In other words, they identify the moment when the voltage waveform transitions from positive to negative, or vice versa. This information is essential for controlling […]

What is an HHO Fuel Cell? An HHO fuel cell, also known as a hydrogen generator or a brown gas generator, is a device that produces a mixture of hydrogen and oxygen gases through the electrolysis of water. This gas mixture, often referred to as HHO or oxyhydrogen, can be […]

What is a Float Switch? A float switch, also known as a level switch, is a device that detects the level of liquid in a tank or container and sends a signal to control the operation of a pump, valve, or other equipment. The switch consists of a floating object, […]

What is a Voltage Converter? A voltage converter is an electronic device that changes the voltage level of an electrical power source. It allows you to convert a higher voltage to a lower voltage or vice versa, depending on your requirements. Voltage converters are essential in various applications, such as […]

Introduction to ATTINY45 The ATTINY45 is an 8-bit microcontroller that belongs to Atmel’s AVR series. It comes in a compact 8-pin package, making it ideal for space-constrained applications. With its low power consumption and rich set of peripherals, the ATTINY45 is a popular choice for hobbyists, engineers, and embedded systems […]

What is a Copper PCB? A copper PCB is a printed circuit board that uses copper as the primary conductive material for its traces, pads, and planes. Copper is laminated onto a non-conductive substrate, typically made of fiberglass or epoxy resin, to create the PCB. The copper layer is then […]
