ok so my teacher wont accept the fact that the circuit he has told everone to use isnt even going to work... he has refuses to let us make our own but i dont realy care as it isnt reght that we all have to use the same circuit cos its easier fr him...
so if anyone has any clues of what way i would go about doing this please tell me
the curicuit needs to do this...
activated by eiter the reed or tilt switchs
then set of an alarm with Flashing led's and a Buzzer and latch on with a thyristor.
the circuit can then be turned off by a key switch to cut the power from the thyristor.
it sounds simple anough but my teacher want to have a 555 timer to do this..
dont worry about parts as i will get them myself because i dont want to be stuck with him trying to tell me bull that things like reed switchs arnt sensitive (which is complete bull as he is just trying to save him self the hassle and the department the money even tho they still charge s for the crap he gives us)
ok so if anyone can give me a hand it would be great...
if you would like more info that is fine just ask
