Hi Beno,
That definitely looks like what I want, but my company requires me to use a corporate purchase order to buy anything so I will try to figure out how to get. I do not mind buying other Opto modules to try, so I will order a couple of those modules.
What is the correct name for a LED light you can wire to a digital output? I do not think I want an alarm light or anything that blinks, strobes, or makes noise, just something I can turn on and off in software while I learn.
For software language, for the backend I want to try out Node-RED, for the front end that the operator would interface with, I am thinking PHP as I know that language very well.
Thanks again,
Josh
