From my OP: The said circuit produces a siren type sound on a buzzer so I added an led through a resistor, a 10k pot and a LDR.
So when light hits the LDR, the alarm goes off.
Again, the same or earlier circuit works fine so I'll just leave it at than now. Thanks
No. A photo of your breadboard is not *clearer* -- in fact it is almost worse than having nothing at all.
And you have still avoided *actually answering the question*. There are three proper answers:
1) I am using bipolar 555's 2) I am using CMOS 555's 3) I don't know, the numbers on the top of the chips are: .........
Three days in, 21 articles, and only *now* do you actually state why you added the extra components. Your OP three days ago left off the "So when ... off." sentence.
Yup, I think we can all agree on that one :-)
