I am currently a G.C.S.E. student. I am studying Technology and Design and for my project I am designing and constructing a phone alarm which activates after a certain time and if the phone is not put down the person will be cut off.
I would be grateful if you would send any information on alarm circuits,cut off switches,or components that would be useful to this project or any other information that might be helpful.
Thank you Gerard.
