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, ...

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 ...

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 ...

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 ...

Here is the circuit diagram of Two Flashing LED’s for different applications (such as model construction), and recreational. Having adjustable flashing speed with two potentiometers. It is the ...

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 ...
