Hello,I know this question has probably been answered a hundred times but I'm having trouble finding a simple solution. I've designed an apparatus that uses a 12v dc motor to open and close a sliding door for our dog. I'm using a DPDT relay that reverses the motor when it reaches the end of it's stroke to then close the door. What I need though is a simple delay, around 10 to 20 seconds before the relay switches the motor to reverse. Thanks for your help in advance.
