simple circuit to close switch for x seconds

simple circuit to close switch for x seconds

(OP)
Hi.  I'm an amateur so please have patience.  I'd like to create a circuit that I can hook up to a household sensor light so that when the light comes on a sound would be produced by something for a certain number of seconds.  I can’t find any retail products to do this so thought I’d try making it myself.  Anything that would guide me in the right direction (eg: read this chapter in this book, etc.) would be appreciated.
Thanks in advance.

RE: simple circuit to close switch for x seconds

Go to www.national.com and look up the 555 timer.  Check out the spec and application notes and see if that helps.

Good luck and keep us posted!

Hi,
I also suppose (just an idea, I can not point you to any website), that you can try to use musical greeting card. Just connect yout sensor output (relay, open collector) to card's switch.

Best Regards
