Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...

This is a simple flashing led circuit with 2 leds and 2 NPN transistors. It illustrates the behavior of transistors and capacitors and if you use an oscilloscope it will be very easy to determine what ...

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 ...

Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...

Like many of us, [Tim]’s seen online videos of circuit sculptures containing illuminated LED filaments. Unlike most of us, however, he went a step further by using graph theory to design glowing ...

Modern LED strips are magical things. The WS2812 has allowed the quick and easy creation of addressable RGB installations, revolutionizing the science of cool glowy things. However, this accessibility ...

LED lightbulbs are more energy-efficient than standard bulbs, but that doesn't mean they work perfectly all of the time. Here ...

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 ...

You’ve probably heard of light-emitting diodes, a type of energy-efficient light. While they’re good for practical reasons—say, illuminating a room or a passageway—they can also add a little bling to ...
