Hi Guys
I have built this 555 circuit and it is working well. It is connected to a set of IR-beams in the garden that switches on a light should someone break the IR-beam as a security measure.
With our winter approaching leaves that fall from the trees tends to trigger the IR-beam.
How can I build/connect a trigger delay between the 555 circuit and the IR-beams, that will ensure that a longer pulse (preferably adjustable) is needed before the 555 switches on the light.
Thank you for your valued response.
