What is Back Drilling in PCB Manufacturing? Back drilling, also known as controlled depth drilling or back-side drilling, is a PCB manufacturing process used to remove unused portions of through-hole vias in high-speed printed circuit board designs. In a standard PCB design, a through-hole via extends through the entire thickness […]

Introduction to Biasing Resistors In digital electronics, biasing resistors are essential components used to ensure that digital inputs are correctly biased to a known logic level, either high (logical 1) or low (logical 0). Two common types of biasing resistors are pull up resistors and pull down resistors. These resistors […]

What is FR4 Material and Why is Yellowness a Concern? FR4 (Flame Retardant 4) is a commonly used material for printed circuit boards (PCBs) due to its excellent mechanical, electrical, and thermal properties. It is a composite material made of woven fiberglass cloth impregnated with an epoxy resin binder. FR4 […]

Introduction to Sirens Sirens are a type of audible warning device that produces a loud, attention-grabbing sound to alert people in various situations, such as emergencies, alarms, or public announcements. They are widely used in emergency vehicles, industrial facilities, and public spaces to signal potential dangers or convey important information. […]

Introduction to IoT and BLE Nano The Internet of Things (IoT) has revolutionized the way we interact with everyday devices. By connecting various objects to the internet, IoT enables seamless communication and data exchange between devices, creating a smart and interconnected ecosystem.

What are Arduino Data Types? Data types in Arduino define the type of data that a variable can hold. They specify the size and format of the data stored in a variable. Arduino provides several built-in data types that you can use to store and manipulate different kinds of data […]

Introduction to Bluetooth Positioning Bluetooth is a wireless technology standard for exchanging data over short distances from fixed and mobile devices, and building personal area networks (PANs). It uses short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz, and was invented by telecom vendor Ericsson in […]

ATM Anatomy The anatomy of an ATM can be broken down into several key components: Display Screen The display screen is the primary interface for the user to interact with the ATM. It displays instructions, prompts, and information to guide the user through their transaction. Modern ATMs often use touch […]

What is an OLED Display? Before diving into the specifics of the SSD1306, let’s briefly discuss OLED displays. OLED displays are a type of flat panel display technology that uses organic compounds to emit light when an electric current is applied. Compared to traditional LCD (Liquid Crystal Display) technology, OLED […]
