First line is just to hi from a new user.
Its been a while since I did electronics (Army/Signals TeleTech Sys) and have forgotten most of it, so I would be greatful for any assistance.
I'm looking to put together a faily simple circuit:-
Electro-magnet, timer, switch, sound module on a 12v supply.
Position 1 of the switch should cause the magnet to be live, position 2 should start the timer sequence and end with cutting the supply. During the count down sequence I would like the sound module to say a couple of words (recording) and have 3 beeps before the magnet goes dead, the whole sequence should last about 5 seconds.
Hope this all makes sence and I would appreciate for any help.
