hi guys,
ive a lot of problems with ldr circuits and I need it for my hand dryer diy project.
as I emphasised in pictures, I just combined LDR circuit with 3sec 555timer. it doesn't work this way and sadly I don't have ability to design new circuit, so I need your help here.
so
-the goal is to drive a relay for hand dryer , at least stay ON for 3 seconds without shot down, and I want it keep going as long as it detects hand.(smooth, without interrupt)
-of course LED in picture (part2)will be replaced with relay(that was just a simulation to see if it works )
-IR light and reciver will be used(like those which are used in TV control)
