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, ...

“1001 ways to blink a LED” is a blog named as a tribute to my passion of blinking LED on any device I can find. The concept of this blog is to give readers source code to use different libraries, ...

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 ...

In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...

Computer monitors often include one or more LED indicator lights that show these devices' operating status. Monitor manufacturers can build a set of signals -- made up of sequences of LED flashes and ...

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 ...
