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, ...

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

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 ...

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 ...

This is a flashing led lights circuit powered from a 12V DC power supply that uses the well known 555 IC. Flashing lights have many and varied applications in life. They are used as warning lights on ...

When you ask for recommendations on which 3D printer to buy, damn the cost, the Ultimaker is consistently at the top of the list. There’s a reason for the popularity of this printer — it’s easy to use ...

It is the time of year when decorations appear everywhere and everyone has a preferred style, from bright flashing lights to ...

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 ...

Hackspace tinkerer Koka Nikoladze has built an impressive electromechanical monophonic step sequencer called the BlinkWheel. The looped sounds are triggered when a rotating arm comes into contact with ...
