Hello every one.
I have build a simple alarm system (see picture at the bottom)
but now I don't Know what I'm suppose to do. we have free build in school and we are suppose to build some thing that are a alarm. We had to build this (see picture at the bottom) But I most warn you I did the picture on 5 min or so, so it's not good...
So do any one have any idea on what to build on it?
I got a idea on some lasers but I dunno how to build that...
OBS: I will get the more info and picture tomorrow when we have the lesson... And dunno if I did the PNP and NPN right tho...
and the resistor I dunno what number...
I guess it would be better to post this when I know more but I have like 2h before next lesson...
