some 5..6 years ago, I bought a bunch of rotary ancoders with both, RG
(not B) LEDs and push button integrated.
I got them from ebay... chinese make, but they also sold those
(seemingly identical) at SparkFun.
They used to work back then. They had positional "clicks" in them.
Just a few years later, just form laying around, those "clicks"
magically disappeared, and one of the A,B outputs would give a garbage
signal, for every single of the 20 or so pieces I had bought.
As if some material inside dissolved.
Ever heard of such a thing?
Since then I have been reluctant to buy such stuff again ... ;-)
