Please I need a delay circuit for 3 to 60 sec using LM324N that used in protection devices for homes. I tied to simulate a wrong one like the below https://www.circuitlab.com/circuit/y3p2sz/lm324-timer/

Sorry but your link is broken.

Thank you for rapid response. Can you try again this link please?
