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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
