This circuit was originally designed in 2003 by using IC 555 as a 30kHz square wave frequency generator. The red LED lights up immediately when the circuit is turned on. … Read more →
IC 555 in this circuit is configured as a monostable multivibrator that has one input. because monostable circuits have a certain period, the number of periods is determined by a … Read more →
This circuit is called a bi-polar led because it consists of two LEDs, each of which has a different polarity. These two LEDs will emit light alternately. The light turnover … Read more →
