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, ...

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 ...

An earlier Idea For Design (“Hardware-Based LED Blinking Control Eliminates Software Overhead,” Sept. 27, 2007, p. 52) described a very interesting way to offload the software overhead required for a ...

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 ...

This time, I will try to run and debug the LED blinking using the Raspberry Pi Pico 2 and Raspberry Pi Debug Probe provided by the Raspberry Pi development team. I will use Ubuntu for building and ...

AC mains operated single LED flasher circuit, built using the popular CMOS timer chip TLC555 is shown below. The whole circuit is powered directly by the grid supply of 230VAC through a capacitive ...

It's easy to ignore your ethernet port's blinking lights, but in reality these signals could be communicating crucial information regarding your connection.

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 ...
