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 ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

[Peter] needed to drive a high power LED for his microscope. Rather than pick up a commercial LED driver, he built a simple constant current LED driver and fan control. We’ve featured [Peter’s] ...

I needed a simple LED indicator showing that a particular voltage level had been reached—specifically, that a capacitor had charged to a particular potential. I was convinced that there must be a way ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

So, your company has decided that it has either found a niche market or an industrial customer(s) with a sufficiently large volume to justify a business case for some kind of LED lighting. Now what?

These light up paper circuit cards were much easier to make than I expected and only need a few inexpensive materials.

Originally hailing from Troy, Ohio, Ry Crist is a writer, a text-based adventure connoisseur, a lover of terrible movies and an enthusiastic yet mediocre cook. A CNET editor from 2013 to 2024, Ry's ...

This is an automatic emergency lamp with day light sensing, means it senses darkness/night and turns ON automatically. Similarly it senses day light and turns OFF automatically. A simple emergency ...

LED (light-emitting diode) bulbs are longer-lasting and more energy-efficient than their incandescent counterparts. But that doesn't mean they last forever. If your LED bulbs are burning out well ...
