Description
KY-040 Rotary Decoder Encoder Module
The M274 360 Degree Rotary Encoder Brick Sensor Module is a rotary input device (as in knob) that provides an indication of how much the knob has been rotated AND what direction it is rotating in. It’s a great device for stepper and servo motor control. You could also use it to control devices like digital potentiometers.M274 360 rotary Degree encoder, is an incremental electro-mechanical device that converts the angular position or motion of a shaft or axle to digital code. The output of incremental encoders provides information about the motion of the shaft, which is typically further processed in /controllers into information such as speed, distance, and position.

Customer Reviews
nice boards and knobs, also it does have amounting nut and washer screwed down on body. Each encoder is packed in its own bag with knob which provides better protection during shipping.
I just wanted to say that these are exactly as pictured. Which isn't always the case when ordering KY-040 units e.g. other suppliers picture the threaded version, but ship the unthreaded version. I need the threads (wood enclosure), and these have threads.
One of them failed on me but good thing i had 5.
I have only tried one. It seems to work as it should.
Excellent
It's a really good device, works as expected. It's logic is pretty simple: when CLK signal falls down, check the state of DT: if it's also "0" (zero) then it's a clock-wise rotation, if it's "1" - you're rotating counter-clock-wise. And of course you need some logic for de-bouncing.
great encoders and they have a switch integrated into the knob.
Good product, but when I was trying to set up a basic counter on my Arduino I could only get it to count forward. Once I removed the resistors from the back of the board it worked as it should.
Works good
Works as expected.Some bounce on switch but that's to be expected.
