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, ...

The project illustrates high power LED being driven to create a cheap and simple blinking LED. The idea behind the blinking effect is done by connecting the LED in series with a blinking light bulb ...

This is tutorial number 1 from our series of Arduino tutorials and in this part I will talk about blinking an LED using the one already available on the Arduino Uno board or using an external LED to ...

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 ...

There are plenty of utilities out there to control keyboard LED indicators, but I'm rather interested in controlling the power LED on my headless 1U rackmount. While theoretically there are tons of ...

An earlier Idea For Design (Hardware-Based LED Blinking Control Eliminates Software Overhead) described a very interesting way to offload the software overhead required for a microcontroller to drive ...
