Hi I am sorry for bothering you with an urgent question; I had an IR light barrier connected to a piece of work of mine. Yesterday it found out that it's too slow, and so I decided to buy a laser light barrier. I connected it to a 12 V DC adapter (it works!). Now I want to connect it to my Arduino …

You will need to provide information about the light barrier (for example, a link to the datasheet) before anyone can answer your question.
