In this project, I'll make a small circuit capable of blinking lights, on its output we get a digital signal that we can use ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components to a 555. But you needn’t go so fancy! [The Design ...

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 ...

Signals when an on-circuit battery is exhausted, 5V to 12V operating voltage A Battery-status Indicator circuit can be useful, mainly to monitor portable Test-gear instruments and similar devices. LED ...

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 ...
