Hi this is my first post here and I'm really hoping someone here can help me. Here's the basic layout for what I'm trying to do. I have a 1/8'' mono output line that sends out a signal anytime i connect my reed switch that I have it hooked up to but I want that signal to be delayed but about 1/2 a second or so and I want it to be customizable in case I 1/2 isn't exactly what I want. I know it's possible to do this. I'm assuming I would need to use a 555 Timer circuit but that's about as far as my knowledge base goes. Can someone please help me with this? A schematic would be great or any other help too. If there's already a device like this for purchase from like Radio Shack or something that I'm not aware of that would be cool too.

EDIT I've also found this schematic: http://www.electronics-project-design.com/images/timedelaycircuit.gif , but I'm not quite sure how if this is what I need, or if this will work with my 1/8'' mono input or how to use it or how much delay this would provide or how to change the amount of delay it's providing
