burglar alarming latch

future is here
I was in 9th standard then. Every year our school organized "ANNUAL SCIENCE EXPO". That year I participated and after lot of discussion I made "burglar alarming latch".
Actually in that project I used LDR (light dependent resistor). First I made a house using cardboard, then at the door of the room I fixed LDR. LDR is sensitive to light. Slight change in intensity of light can trigger the alarm connected to that LDR.
It worked really very well. I got second prize for that even. I have a certificate for that also. School science fairs
are really very encouraging, as they help children to think of something new yet something creative.
Yes I would like to do it again.Barry's Response
- Yes, Kumar, we need more sensors. They can function as our eyes and ears when we're not around, and may be an important step in the eventual creation of artificial intelligence.
