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 ...

This is a simple LED Cube circuit designed using 555 timer. It can be very useful for home decoration purpose and home lighting systems. Many LED Cube circuits are available in the markets which are ...

Semtech has introduced an analogue timer chip that runs from 0.9V, but can drive LEDs at over 3V. Called SX8122, to the timer it adds: a simple battery charger, a boost converter, and a power-down ...

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 ...

エンジニアとしてセンスを磨く方法はいくつかあると思うのだけど、私のお気に入りは過去の優れたマスターピース(技術的傑作)に触れることだと思います。 集積半導体におけるマスターピースの一つは間違いなく555タイマ、8本のピンと内部に2つの ...

When asked to whip up a simple egg timer, most of us could probably come up with a quick design based on the ubiquitous 555 timer. Add a couple of passives around the little eight-pin DIP, put an LED ...
