Black Rotary Encoder Module Brick Sensor Development KY-040 Fit For Arduino

This model seemed like it had a little less "bounce" in it than another module I purchased with a similar design..I guess that's a good thing but I can't guarantee that is typical of every component.Since it was my first time using this type of component it took a little while to figure out how to wire this up to a raspberry pi - everything was soldered on properly - just needed to use a few jumper wires to make the GPIO connections.http://forum.arduino.cc/index.php?topic=242356.0http://theatticlight.net/posts/Reading-a-Rotary-Encoder-from-a-Raspberry-Pi/..able to make it work with Bob Rathbone's python rotary encoder class.http://www.bobrathbone.com/raspberrypi/Raspberry%20Rotary%20Encoders.pdf..as a part of building an internet radio using his specifications.http://www.bobrathbone.com/raspberrypi_radio.htm

Works as expected. Arrived as pictured. In particular, it does have the screw threads shown. Not that it does not ship with a mounting nut though. My favorite feature is that no soldering is required for project use. For documentation on this part, see http://www.stuffaboutcode.com/2015/05/raspberry-pi-and-ky040-rotary-encoder.html.

This rotary encoder has a push button and click-y perforated feel to its movement, which is exactly what I needed. I ended up buying a few more of these since they worked so well. I put a black knob on the post, works like a charm.

very good products

Works great and quick delivery.
