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 as hoped easy to connect and solder and work exactley as hopedused in a sim button control box and work perfectly

I use these as a digital volume control with my raspberry pi media streamers. Work well.

A quadrature encoder is an incremental encoder with 2 out-of-phase output channels used in many general automation applications where sensing the direction of movement is required. Each channel provides a specific number of equally spaced pulses per revolution (PPR) and the direction of motion is detected by the phase relationship of one channel leading or trailing the other channel.The item description could be clearer as some have assumed that this item will output, as stated in the description gray codes. This is incorrect this item outputs two out of phase channels.

Replaced an unserviceable part in my LiPo charger, which meant I could once again use both sides of my charger! Only needed the one but means I have another in case the other side does the same thing! Very happy that for the small cost of the encoders and an hour of my time my £200 charger is fully functional! Time will tell how long it lasts but it's working now and that's all that I'm concerned about 🙂

I bought this to use in an ESP32 project, to work with a 64x128 display to develop a menu system. The code was relatively easy to develop, and there are loads of examples out there. Very pleased with end result. The push switch is a little clunky and takes effort to push though, so may not be ideal for use in thin panels. Certainly worth looking at, given the price.

These are nice little encoders and very reliable. I've used several to control simple Arduino/ESP32 projects.The negative reviews assume they should output a Grey code but that is incorrect. Look up "Quadrature Encoder".The photo shows one being used with an ESP32 and the 'encoder_example' from esp-idf-lib.

As somebody else has said, these are not usable as rotary encoders. The push-button switch seems fine, but there is a massive problem with rotary part.Instead of a standard Gray code (that's Gray the person, not grey the colour), the A & B outputs briefly pulse before going back to the previous state. Usually. You should get 00 - click - 01 - click - 11 etc. but the outputs will give "something" as the switch goes click and then revert back. I took one apart (a distructive process) and I think the encoder must be misaligned. One I would accept as bad luck, but the fault is across all of them. I used test equipment to confirm this.So basically, they're useless unless you want a strange spinning push button.I'm outside the returns window so I have to console myself with the fact that at least I can use the knobs when I get some switches that work from somewhere else.

After spending two evenings on trying to make it work, I have no success. I am still not sure though is that the device fault or me not wiring it properly. There lot of people saying that these are working and you just have to find more information. Nobody actualy gives that information. Impossible to find datasheet either. So please, anyone who got them to work, describe more detailed how you did it. Thanks.
