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 purpose of building this circuit is to create a LED flasher with alternating sequence from the two LEDs where the operation is based on the functionalities of a 555 timer integrated circuit. 555 – ...
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 ...
