Is it in yet?  Need garage parking clearance sensor with display design

Occassionaly, we don't pull the car in far enough.  The door comes down and scratches the back of the car.

I would like to display a red led whenever there is an obstruction (car) breaking the beam.

 

I want to construct a photo sensor solution?

  1. inexpensive and educational for my children to participate
  2. reliable
  3. display a red led whenever beam is broken
  4. door opening is 22'
  5. led will be at front of 24' garage

 

I see a broad array of emitters and sensors.

 

But, I need a recommendation to integrate with a controller and transformer.



 

I am capable of fabricating mounting brackets, soldering, etc..

 

Is there a kit or source of simple designs like this?  I tried the reference library and didn't fine one.

 

Thanks...

DMS
