Applications for using a single pushbutton to advance a circuit to its next logical state are legion. Typically, there are just “on” and “off” states, but there can be more. The heart of the circuit ...

Here’s your useful and beautiful circuit for the day — [New Pew]’s vibration sensor takes manual control of the flip-flop inside a 555 timer and lights an LED in response. Use it to detect those ...

The flip-flop, in whichever of its several forms you encounter it, is a staple of logic design. Any time that you need to ...

Many varieties of ON/OFF control circuits use some form of flip-flop that responds to a pushbutton switch or other control input. These all have volatile memory and default to an OFF condition if ...

In this paper, the authors deal with the testable design of conservative logic based sequential circuits by using two test vectors. The conservative logic based sequential circuits are built from the ...
