Adafruit Rotary Encoder + Extras [ADA377]

Description

This rotary encoder is the best of the best, its a high quality 24-pulse
encoder, with detents and a nice feel. It is panel mountable for placement in
a box, or you can plug it into a breadboard (just cut/bend the two mechanical
side tabs.) We also include a nice soft-touch knob with an arrow in it, fits
perfectly and looks great. This encoder also has a push-button built into it
so you can press onto the knob to close a separate switch. One side has a 3
pin connector (ground and two coding pins) and the other side has two pins for
a normally-open switch. Rotary encoders are useful as rotation sensors or
selectors and look similar to potentiometers. However they are not like
potentiometers at all, so it’s important to realize the difference! These
rotary encoders rotate all the way around continuously, and are divided up
into 24 ‘segments’. Each segment has a click-y feeling to it, and each
movement clockwise or counter-clockwise causes the two switches to open and
close. There is no way to know what the current ‘position’ is – instead you
would use a microcontroller to count how many ‘clicks’ left or right it has
been turned. If you need to detect rotational ‘position’ a potentiometer would
be a better choice.
