As I mentioned in my recent columns on the topic of adding pull-up or pull-down resistors to the inputs of unused or partially used logic gates and functions (see Part 1, Part 2, and Part 3), I was ...

Logic Gates are among the important components of a circuit. All the logical operations required to perform a particular task in an electronic circuit are carried by these logic gates. If you are an ...

The circuit was designed to create a handy logic probe that can show off the logic states for high, low and pulsing outputs with the use of CMOS 4001 integrated circuit. Logic Probe – a handheld probe ...

Scientists have succeeded in developing logic circuits equipped with diamond-based MOSFETs (metal-oxide-semiconductor field-effect-transistors) at two different operation modes. This achievement is a ...

While working on recreating an “ancient” (read: 60-year-old) logic circuit type known as resistor-transistor logic, [Tim] stumbled across a circuit with an unexpected oscillation. The oscillation ...

Often, it becomes necessary to interface an existing or new 5V AVR / PIC / MCU project to new devices that use 3.3V logic, like memory cards, sim cards, etc. Described here is a circuit that converts ...

A rduino boards are a popular choice for DIY electronics, but it's not always clear how to get started with building projects ...

Transistors, the fundamental building blocks of digital logic, are now being made just a few dozen atoms wide. At these incredibly small scales, traditional silicon fabrication faces significant ...
