Hello again
I tested the circuit in breadboard
I am facing this problem
When connecting pin 14 of U1 to pin 2 of 555
the counter only shows zero and not changing also I found that the LDR should be in very dark place so the buzzer get activated
See the quote from Audioguru in my post above. There is no point in us giving you advice if you don't take heed of it.
That’s why I decided to connect pin 14 of U1 to pin 3 of the 555
and the lDR is working fine and the sensitivity is perfect
but facing this problem
the counter starts from 0 zero and when the buzzer stop making sound
it shows 1 wow it counts
But here what will happen
when the buzzer activated again and stops the counter return to Zero !!!!
See below.
so it's like this
zero one zero one zero one
how can I make it counts zero one two three ....... and so on !!!
