Your Ryobi battery charger LED lights notifies you of more information about your battery than you think.

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 ...

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, ...

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 ...

Time for another update for the Hackaday 68k, the 16-bit retrocomputer developed on Hackaday to show off both our love for vintage hardware and our new project hosting site. There’s still invites to ...

Modern Wi-Fi routers give you a lot to work with in terms of troubleshooting issues at home. This is mainly in the form of various LED (light-emitting diodes) indicators that flash to show what ...

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 ...

I’m not really sure if this is good or bad news for end consumers, but a couple of Japanese companies have developed a technology that makes it possible to transmit information from blinking LEDs ...

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