I purchased a couple quadrature incremental rotatory encoders (ACZ16NBR1E-20KQA1-12C) and they're not responding as I had expected.
To test them, I connected phases A & B to 5V through LEDs and Common to ground. Yes, I know it'll damage my LEDs, but I just wanted to see the encoder work for the first time. I expected to see each LED light up 2 times for every 4 positions of the dial.
Instead, I see very erratic behavior. Typically the LED only lights up half-way through a position change. Sometimes the LED will stay on after I reached a position, but it occurs much less often than 50% of the time.
This is my first encoder experience. Please help!
