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 ...

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 ...

Flashing, spinning, and oddly blinking LED indicators have become the modern equivalent of red warning lights on a car dashboard. Rather than giving every potential problem and function on a ...

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 ...

The project was based on 3 LEDs to form the Red, Green, & Blue in place of a real RGD LED on a PCB that is connected to the controller using a 1m long 4-wire cable. The project was based on 3 LEDs to ...
