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 ...

I could have done it with a 556 (2x 555 in one package, use the second one as a flip-flop) but when I costed it out, an AtTiny13a turned out to be cheaper. Fun times. Report comment ...

IC 555 is a highly stable integrated circuit functioning as an. Aspencore network. News & Analytics ... When a negative going pulse is applied to pin 2, the potential at pin 2 falls below 1/3 Vcc and ...

The output of the flip-flop also is connected to a transistor that connects the Discharge pin (Pin 7) to the Ground. Quick Modes Refresher A 555 timer can be employed in several different ways.
