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 ...

It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillator, ...

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 ...

Computer monitors often include one or more LED indicator lights that show these devices' operating status. Monitor manufacturers can build a set of signals -- made up of sequences of LED flashes and ...

Nowadays, single-color and multi-color flashing LEDs are easily available, which obviates the requirement of external chips to produce fascinating lighting effects ...

Almost every micro-based project that I have designed in the past 25 years has had a flashing LED, originally as a “health” indicator, but the feature has expanded to use as a status indicator where ...

The ubiquitous LED continues to expand frontiers and applications with a plethora of sizes, colors, and output lumens. Flashing LEDs that incorporate internal ...

Often, HP laptops are configured to go into sleep mode, causing data stored in RAM to be temporarily moved to the computer's hard drive when the lid is closed on the device. This is the default ...

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 ...
