Hi all
I am new to the forum and have probably an odd question.
I am one of the owners of a small brewery and we have a canning line. The canning line has a 3 foot tall stack of lids for the cans that drop down one at a time. Its basically a big tube with lids stacked.
We have to monitor it visually all the time to make sure it doesn’t run out of lids.
Is there a way to build a sensor that would detect (laser) when the lids were running low? Something audible is ideal.
Attached is a rough drawing of it
Just learning about Arduino so any help on what is needed (without acronyms) is greatly appreciated!
Cheers
John
