Hi, I am doing a product design course and do not cover any electronics so even though I think this is quite a basic circuit I cannot be sure its correct.
I basically need to create a circuit with a tilt switch, once the tilt switch gets activated it needs to have a delay of 10 seconds before it sets off a siren. If the tilt switch gets reset it will then need to start again from 0.
Once the circuit has be activated and the siren is on there should be no way to stop the siren apart from disconnecting the battery.
Is this circuit correct and give me what I want?
Using T = C x R
To give 10 sec = 10uf x 1m ohm.
The relay will be connected to the Siren to set it off
