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 ...

The circuit has a fairly simple explanation. U1 is a counter. Figure 1 A Flip ON Flop OFF circuit for DC voltages. The gadget is connected to the output terminals of the PB. With an adequate heat sink ...

Toshiba has launched a transistor array for LED lighting and industrial, high-voltage signal transmitters. The TBD62089APG incorporates 8-bit, D-type Flip Flop circuits that support a data storage ...

Figure 1 F1a regeneratively debounces S1 so F1b can flip ON and flop OFF reliably. An (almost) universal truth about mechanical switches, unless they’re the (rare) mercury-wetted type, is contact ...

This circuit uses a dual-D flip-flop and an OR gate (Fig ... creates innovative light-show systems using LED or video displays, and also does some contract consultation.

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 ...
