While LEDs are common in voltage detection applications, I have never seen an LED circuit that is dedicated to indicating the presence of low values of current flow. This simple LED current sensor ...

Sometimes the most useful hacks are also the simplest ones. A case in point is the LED and resistor assembly that [Skippy] recently posted on his blog. The idea is to solder up some pre-made ...

This LED DC voltage indicator circuit is a voltmeter, rather than simply a battery tester. As such it may measure voltages as low as 3V. It utilizes venerable LM741 operational amplifiers applied as ...

Waytek has added six new LED indicator lights to its product line to complement its incandescent indicator lights. These new LED indicator lights come Waytek has added six new LED indicator lights to ...

ROHM Semiconductor has announced its new low current, high brightness chip led SMLx family featuring various package sizes and colour ranges for usage in advanced automotive cluster and indicator ...

Diode Inc.’s 18-/12-channel linear LED drivers deliver precise digital color mixing and brightness control for vivid lighting ...

Indicator and backlighting assignments can both be tackled by three new high-intensity SMT LEDs. Available in blue (TLMB3140), blue-green (TLMBG3100) and pure green (TLMTG3100) styles, the LEDs are ...

The ubiquitous LED continues to expand frontiers and applications with a plethora of sizes, colors, and output lumens. Flashing LEDs that incorporate internal electronics for oscillation offer ...
