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 ...

Light-emitting diodes are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the constant-current ...

Discover the step-by-step process of creating a powerful music reactive LED strip circuit in this comprehensive tutorial. This video will guide you through the essential components and techniques ...

I was tired of replacing my LED lights when they should have lasted for years, so I asked the pros why it kept happening.

In many consumer applications for lighting the cost of existing technology – namely incandescent light bulbs or fluorescent tubes – is so low that LED lighting’s many advantages simply cannot make up ...

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 ...

The basic circuit illuminates up to ten LEDs in sequence, following the rhythm of music or speech picked-up by a small microphone. The expanded version can drive up to ten strips, formed by up to five ...

When Raj Patel looks down from an airplane, he doesn't see streetlamps dotting the ground. He sees potential business partners. Patel founded Ferndale-based Midwest Circuits, now a municipal LED ...
