If you've ever used a Wi-Fi router to connect to the internet, you've probably wondered what all the blinking lights mean.

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 ...

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 ...

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 ...

American motorcycle manufacture Harley-Davdson has just announced the release of new flashing LED police mirrors, offering customers the possibility to choose between any combination of red and blue ...

The eyes may be the window to the soul, but the blinking LED lights on a modem are more forthcoming, two researchers revealed this week in a proposed submission to a security journal. Joe Loughry, an ...

Checking a text on your mobile phone while crossing the road might seem harmless, but if you are unaware of the traffic flying by it could have tragic consequences. A QUT study found flashing LED ...

This is a simple flashing led circuit with 2 leds and 2 NPN transistors. It illustrates the behavior of transistors and capacitors and if you use an oscilloscope it will be very easy to determine what ...
