5 Set 360 Degree Rotary Encoder Code Switch Push Button EC11 Digital Potentiometer with Switch 5 Pin Handle Length 20mm and Knob Cap for Arduino Electronics Projects

Work great on the project I was working.

I was unsure at first, because a multimeter shows an open circuit from GND to A and GND to B.However, it is definitely doing four pulses per stop, with each stop open circuit, presumably to make it so a pull up resistor won't be wasting power.I was able to use the Encoder library for the Teensy (pjrc) and it had a lot of noise (scores of pulses) but overall it still went a predictable four steps per stop.I wouldn't recommend them highly, but at least my batch was tolerable.

I tested all five of the encoders and all were working fine. Not very high resolution, with only 20 pulses per revolution, but perfect for simple OLED menu control. I've successfully used them in multiple such projects.I prefer this style (threaded shaft with nut) as they're easy to mount in a box compared to the ones on a PC mount module.Great value at two bucks each, with knobs included.

This rotary encoder works reliably and has a strong click feel as it moves through each position. The legs are quite malleable though and I was not able to pin them into a breadboard without them popping right out at the lightest touch. Once actually in a soldered circuit though they have worked very reliably for me

they do not function very well at all, outside of the click. the rotary action is quite poor. it will frequently register going in either direction no matter which direction you turn it. the only way to get an expected result is to start to turn the knob, without allowing it to click past its position. but if you go to far it will read the opposite direction. also, if you do this it thinks the dial is being forever turned.i tested 4 of 5 pieces and just dont have the patience to wire up the 5th. i know what will happen. this is a very low quality product as mentioned by other reviews.. i just didnt read them before it was too late.save yourself some money, dont buy them or get a different piece of equipment from someone else.

Very good pots, love the added button. Great for menus like on 3d printers. seems very well constructed and worth giving it a go.

Used these for an Arduino project. They are very smooth with noticeable detents and the button has a nice click. 1 star removed because one encoder sometimes would register rotations in the opposite direction when spinning fast.

Perfect
