Jeg har brug for et godt råd til at kunne retrigge en 555 monostabil. Jeg har fulgr flere forskelleige application, men uden held. Jeg skal altså kunne trigge før perioden er udløbet uden afbrydelse. (Der findes ellers et hav af forskellige application men ingen der opfylde mit ønske.)
På forhånd tak for svaret.

Hej Børge
Her er en der laver kunster:
"Retriggering is made possible by transistor Q2, which acts to rapidly discharge the 10mF timing capacitor should a pulse arrive when the timer is already running. This means that once triggered, IC3?s output will remain high as long as additional trigger pulses are received within its set timing period."
