Discover the step-by-step process of creating a powerful music reactive LED strip circuit in this comprehensive tutorial.

A middle school design and technology teacher breaks down a three-project unit that nicely overlaps with STEAM content.

Analog designers often need matched resistors. One solution is integrated resistor networks, but what if they don't offer the ...

When light strikes the photodiode’s active region, current flows from cathode to anode. Ideally, this entire photocurrent ...

This study proposes a novel light-emitting diode (LED) driver circuit that stabilizes the lighting output without a photodiode. The LED driver circuit is composed of a self-alignment circuit to ...

Build a modern twist on the classic Theremin using time-of-flight sensors and analog sound generation. No musical talent required, just a love for tinkering!

Given the performance decay of high-power light-emitting diode (LED) chips over time and package condition changes, having a reliable output light for sensitive applications is a point of concern. In ...

The compact “Multitester” design combines a logic probe, clock pulse detector, and voltage detector into one audio-feedback device.
