This category covers the fundamental building blocks of digital electronics, focusing on logic gates (AND, OR, NOT, XOR, etc.), digital circuits, and their applications in modern electronic systems. You’ll find detailed articles on how these logic gates function, how to design digital circuits, and the importance of digital electronics in everything from microcontrollers to advanced computing systems.
What is a 7-Segment Display? A 7-segment display is an electronic component made up of 7 individual LEDs arranged in a specific pattern to display digits (0-9) and some letters. These LEDs are named a, b, c, d, e, f,
In the world of Internet of Things (IoT) development, the ESP8266 and ESP32 are two of the most popular Wi-Fi modules available. Both are powerful, cost-effective, and widely used by hobbyists and professionals alike. While both belong to the 32-bit
Introduction to NOR Flash and NAND Flash NOR Flash Intel first developed the Nor Flash technology in 1988. Nor Flash is characterized by on-chip execution (XIP, eXecute In Place), and its reading is similar to the random reading form of
FPGA, short for Field Programmable Gate Array, is a hardware reconfigurable architecture. In other words, it is a chip that can be programmed to change its internal structure. FPGAs have been used for many years as a low-volume replacement for
Introduction to Boolean expressions Boolean expressions are fundamental components of digital logic design. They represent logical relationships between variables, typically resulting in a binary output. These expressions are crucial for building efficient and reliable digital circuits. In this article, we
Logic Gates are the basic components on Integrated Circuits. Simple logic gates can be made of transistors. The combination of these transistors can make the high and low levels representing the two signals pass through them to generate a high
What is TTL? TTL, or Transistor-Transistor Logic, is a type of digital circuit design that uses bipolar transistor technology to create logic gates. TTL is commonly used in electronics, particularly in the design of digital circuits, because it is fast
What is 74HC245? 74HC245 is an octal transceiver used for asynchronous data transfer between two devices. Furthermore, it supports data transmission at different voltage levels. The internal structure of the chip consists of two amplifiers. Therefore, it can perform two-way
BMP280 is a high-precision sensor module chip that can measure atmospheric pressure and temperature in the air. Not only that, but it can also measure the humidity in the air. This 6-Pin module supports both SPI and I2C interfaces. This
What Is 74LS04? The 74LS04 is a digital logic gate integrated circuit that features six inverters, also known as hex inverters. Each inverter within the chip has an output signal that is the inverse of its input signal. The six
Well Done Technology was established in 2008, focus on reverse engineering, IC unlock, PCB Clone and design. Our technical team of more than 40 people includes senior engineers with rich experience.
