Hello. First time poster, hope I'm in the right place.
What I have:
A secured entry door for guests.
A push-button switch behind the front desk to signal the door to unlock
A low-voltage signal.
Obviously it only sends the unlock signal when the button is pressed.
What I want:
The unlock signal to remain on for 3 seconds after the button behind the desk is pushed and released.
This way the receptionist does not have to hold the button down the entire time.
In my mind this seems very simple. I'm hoping someone here can lead me in the right direction.
Do I need a relay? Something more complex?
Thank you!
Mechanically inclined but a circuit rookie,
Robert
