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 ...

I'm trying to help my son understand flip-flops. He's home from Uni for holiday and has a "workbook" to get thru all about Logic Circuits and Boolean algebra etc. Between us we've been able to ...

CD4027 is a JK flip flop that is generally used for data storing. Here we have presented the circuit diagram of JK flip flop designed using CD4027.CD4027 is a JK flip flop that is generally used for ...

We are somewhat spoiled because electronics today are very reliable compared to even a few decades ago. Most modern electronics obey the bathtub curve. If they don’t fail right away, they won’t fail ...

A flip-flop is one of the most basic digital electronic circuits. It can most easily be built from just two transistors, although they can and have been built out of vacuum tubes, NAND and NOR gates, ...

This circuit uses electromechanical relays to retain its state indefinitely, even when power is off. It consumes no power except when triggered from one state to the other. Many varieties of ON/OFF ...

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 ...
