Hi,
I'm working on a project and need help. I have a small room that I need to setup a couple of devices. This is for an art show im doing, and its suppose to mimic an interrogation room.
So, as you walk into the room (normally lite room)
- a pressure sensor will be setup under a stool
- when you sit on the stool, it trips a relay
- switches off normal lights and turns on spot light over stool
- i then have pre-recorded questions on a cd which i would like to start play whent the spot light is turned on
- when the person stands up i need the cd player to stop, but if they sit down again the cd needs to start again (from the start)
Im really confused how to set this up electronically
I have thought of using a relay that when closed from the pressure sensor, it will close the loop for the speakers (which i thought of letting the cd run on a loop) but I need the cd start at the start everytime someone sits on the stool.
thanks
s.
