Interfacing optoelectric proximity sensor with arduino

Hi,

I am using the first LED, in your picture, everywhere. I got them from the local hardware store. It needs just 3V to light up. Sorry I can't show you a picture of the exact project. I am bound by my company rules.

You don't have anyone experienced in electronics at your work place?

outsider's circuit is what I was leading you, too.

A step at a time so you would understand and learn what is going on.
You haven't answered post #15 yet, to really establish if the output is 24V high output.
Please read the references I have posted so you understand how to drive LEDs.

Tom... :slight_smile:
