D-type flip-flops are used in prescalar/divider circuits and frequency phase detectors. This circuit shows how a D-flip-flop can be made to change state and switch two coloured LED's.
Please note: EveryCircuit has included a power source into some components such as logic gates to save workspace. This circuit hasn’t taken advantage of this initiative yet but also recognises that the included power source isn't indicative of reality and is only applicable in a simulator environment.
