This simple LED driver circuit allows us to drive up to seven LEDs by using a single NiMH (Nickel Metal Hydride) AA cell. The circuit produces voltage pulses at a much higher level than the input ...

The project is a simple way of producing a fading LED without the need to program the chips or write the code but rather using a few simple components with a constant fade up and fade down as the end ...

Regular readers may recall we recently covered a neat Arduino trick that allowed you to “blow out” an LED as if it was a candle. The idea was that the LED itself could be used as a rudimentary ...

Sometimes the best inspiration is limitation. The 555 timer does “one thing” — compares a voltage to a couple thresholds and outputs a signal accordingly. It’s two comparators, a voltage ladder, and a ...

Semtech Corp announced a sub-1 V analog timer platform that revolutionizes the conventional 555 timer for low-voltage, battery-operated small appliances. Semtech Corp. announced a sub-1 V analog timer ...
