what is mean by " when test 1 is low pin 1 is high "
dear moderator , i want if test 1 is high pin 1 is high .. And if test 1 is low pin 1 is low..
ACTUALLY I WANT IF THE ELECTRICITY IS AVAILABLE THE OPTO-COUPLER CONDUCTS AND IT WILL GIVE THE SIGNAL TO THE BASE OF PNP TRANSISTOR ..
SO THE PNP WILL WILL CONDUCT AND TAKE PIN 1 HIGH..
I HAVE ATTACH THE ELECTRICITY DETECTOR CIRCUIT PLEASE HAVE A LOOK....
Thanks again...
If you add a filter capacitor on the output, you can get 5V out. See attachments.
The half wave circuit requires a larger capacitor, and several cycles to get to a full logic level.
The full wave circuit uses a smaller cap, and can get to a full logic level within a half cycle.
