I had a great idea, use an Arduino to control status indicators. i.e. have led’s light up dependent on product status.
I know I can send serial commands over batch script and I recall you can open progams, or .bat files from actions in samba. So Lets say I had a led to show if a workperiod was open, so my employee would only try logging themselves in if the blue led was on. What I think I would do is when a workperiod is started I run the batchscript to turn on the led and when it is closed I run a different script which turns the led off.
Does anyone see any issue in what I am hoping to achieve?
