I apologize if this seems like a fundamental question, but I feel like I'm missing a fundamental understanding about digital rotary encoders, because none of my basic encoders are working as expected.
These are the encoders I'm working with. Link to Encoders
Based on my fundamental understanding of an encoder, it's basically like a double switch that are 1/4 cycle out of phase. At times, 1, 2, or 0 of the encoder pins will be connected to the base pin.
Given this, it seems like the resistance between pins should be either 0 or INF? Correct? Depending on the current position of the encoder?
If the multi-meter was showing 0 resistance (closed switch), and if I move the encoder two clicks, then it should show INF resistance from pin 1 and base, correct?
I'm losing my hair becuase I have several encoders all acting the same way....always showing INF resistance between pins ALL THE TIME.
Please show me what I'm doing wrong.
NOTE: I'm currently hooked up the the pins on the side with 3 pins. Pin 1 and 3 are encoder pins and Pin 2 is the base pin.
I got a response from another forum that mentioned that in a single click the pins complete the entire cycle (A HIGH, B HIGH, A LOW, B LOW). Is this true? Does anyone have a video or article that says this?
