I think that would be kind of cheating because those things are already their own circuit. For this I was going to use something like this: http://www.radioshack.com/product/index.jsp?productId=2049723 http://rsk.imageg.net/graphics/product_images/pRS1C-2110714w345.jpg

Where do you think I could find one of those to buy? How to those work? Do they complete the circuit when it senses something in front of it?

Still need a way to make this circuit work could anyone point me to an easy solution? Edit: What parts will I need?

Unfortunately I do not have any connections to someone with any electronics skills. I am sorry for my lack of experience. Do you still think you could help? Edit: Signing off for tonight Thank you for your interest guys!

There is my drawing sorry if it is not very clear I can try to explain things there if you need.

I'm sorry, I'm kind of confused. I tried to find a way I could draw out the circuit but I couldn't find an easy way it always looked really weird. I'm sorry! Is there any other way I could help explain?

How do I show you the circuit? I only have a pencil drawing for the plan. And yeah I want the circuit to activate then the beam is broken. Thanks.

Thank you very much for replying. To start off I will just say that I only know the very basics although I am very eager to learn. For the sound I haven't decided on anything in particular I was just planning on using a simple noise maker. (I'm sorry I can't be more specific.) The plan...

Hello everyone, I have a project in science and I am puzzled with something. I want to have and IR emitter and an IR detector to act as a burglar alarm that will activate lights and a speaker-like thing. The only problem is that the IR set that I am using opens the circuit until it gets...
