This is a 12-step rotary encoder with a nice 'clicking' feel. It's breadboard friendly, and has a pretty handy select switch (by pushing in on the knob). The encoder is different from a potentiometer in that an encoder has full rotation without limits. The unit outputs gray code<\/a> so that you can tell how much and in which direction the encoder has been turned.<\/p>\n\nThis unit does not come with a knob, but a working knob is related below.<\/p>\n\n
