Arduni for shoting Ray with sensor

Hi, I had an idea for a project and I was thinking to use arduino for accomplish it.

The idea basically is this:

I want a movement sensor that every time is crossed by an object shoot a ray (infrared ray). All the system would be set in small sizes part.

Is it possible with arduino create a thing like this? If yes there are tutorials?

Thanks in advice :):

Break your idea into each, separate, part of your project and get them working, individually. Only put them all together when you have all individual components working.
What do you think of when you write "infrared ray"? Who would know if this happened or not?

There is a receiver that as output has a sound:

  1. OBJ cross the sensor
  2. Sensor shoots a IR to a Receiver
  3. Receiver output a sound

In few words, I want to do a remote with a movement sensor

Distances, angles etc, . An outline for choosing the right components.

There are tutorials for all of those basic components. Search for "arduino something" to find what people have posted about using "something" with Arduino.
