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 ...

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 ...

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, ...

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

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 ...

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 ...

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 ...
