Need Timer and Dual Relay Circuit Design Help

StoshuOGR Forum Member

HI Guy's

My application is this.
At the momentary press of a button I would like to activate a relay
That would start the culvert unloader for 15 seconds. After that a second
relay would start the loader for 15 seconds.

It may sound kind of lame, but I plan to use it at shows where the
little engineers can operate the culvert accessory without any supervision.

I can do this with a mechanical timer and a couple relays but it's kind
of bulky. So solid state would be a better solution.

I was thinking of a 556 timer circuit, but I don't quite understand all
the jargon. Stable,monostable ect.
I'm also not sure about the reset function..

Can anyone help ?

Thanks
Bruce...
