Hello

Some time ago I had an idea that light sensor can be also used as light/laser barrier, as I had some laser module laying around, which i bought some time ago on Ebay so I decided to give a try l, it's still to be tested in action, but it's a good opportunity to share some photos from workshop ;)

In future days I will try to make a some tests for it, generally use case is almost same as for reflection sensor, but sometimes I think it can be handier to use such laser barrier and I wanted to make use of those modules which i got lying around ;)
