I got a burglar alarm made from outside for my physics project. I showed it to my sir but he said it was an older version of the system(as in the circuit is open when the wire breaks instead of the usual ldr alarms i guess). It slightly confusing and i was wondering if a more in depth explanation of it could be givin? i have to show this in exam and even viva will be asked from it.
(the diagrams and all are given in the attachments)
thanks a lot
p.s. i know i shouldnt have got it done from outside
