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 ...

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 ...

High-brightness LEDs, with independent delay and duration, find use in a visual-inspection application. This circuit is not complex, but it saved the day in an application involving visual inspection ...

The flashing is thanks to LEDs with a built-in, integrated flashing circuit and the nasty noise comes from a piezoelectric buzzer — both are available from electronics stores that sell ordinary LEDs.

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 ...

The fabric of the future won't be just plain chiffon, silk or cotton. Instead electroluminescent material, microprocessors and LEDs may be woven together with clothing fibers to create smart textiles.

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 ...

A hybrid conductive material which can be bent and stretched has been developed by a team of researchers in China. Circuits made with this part elastic polymer, part liquid metal hybrid – known as a ...
