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 ...

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 ...

A counter counts the bounces and flip-flops act crazy, so reliable operation requires the elimination of the bounces. Switch-debounce circuits have been around for a long time, but I'm revisiting them ...

More complex circuit elements, such as flip-flops, inverters or Schmitt triggers, are created from various permutations of these building blocks. For example, when two transistors are combined to ...

Figure 5: Schematic representation of a 'flip-flop' circuit in feeding regulation and testing predictions based on the circuit. Our appetite can be regulated by the appearance, smell and taste of ...
