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 ...

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 ...

LEDs are often used on manmachine interfaces (MMIs) or device front panels to illuminate switches or backlight text information so that the user knows what the device is supposed to be doing at the ...

Blinking an LED is generally considered the hardware equivalent of the classic “Hello World” project. It’s a quick and simple test to show that you’ve got the basics worked out, and a launching point ...

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 ...

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

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 ...

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 ...
