Blinking an LED is generally considered the hardware equivalent of the classic “Hello World” project. It’s a quick and simple test to show that you’ve got the basics worked out, and a launching point ...

Not just for nerds, anyone with an interest in electronics, computers, or engineering can build a circuit to blink an LED or read a temperature sensor. The NerdKit will walk you through building the ...

In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...

This simple project aims to build a circuit that can make the LEDs blink with the sound that comes out from the P2 connector. Shown in the video is the LED blinking in action. The design of the ...

You know how it is. You’ve got that new project running, and while it doesn’t consume much power, it also doesn’t give much indication of whether it’s functioning or just sitting there with a dead ...

When an organization needs to make sure that a computer is as secure as possible, it will often "air-gap" it. An air-gapped computer isn't connected to the Internet. It's not even networked to other ...

Researchers say sensitive data can be extracted from air-gapped networks via a wireless router’s blinking LEDs. Researchers have uncovered a new data extraction hole inside air-gapped networks that ...
