Ok, this is quite hard to explain (for me!!!) so hopefully you can kinda guess what I'm saying.

For my GCSE project at school I need some help for it!!

I am making an infra red security alarm, but I cant find a site that has parts which actually exist for the circuit!!!

Please could anybody help me find a design for this as I'm finding this difficulkt at the time

Any point in the right direction would be much appreciated!

scuse me?

Sorry, my browser screwed up the address, I'll post the correct one soon.
