Rotary encoders are devices that can convey the position and direction of rotation through the use of two output channels, A and B. So we’ve made a breakout board that is both breadboard friendly and super easy to put together!



(Chicken head knob not included in kit)

Kit Parts:

• TurnMe board
• 2x 5pin male headers
• 1x rotary encoder
• 3x 1k ohm resistors

Build Notes:

• 2x 5 pin headers: One of the 5 pin headers is for breadboard support (if desired), and the bottom 5 pin header allows for interfacing with +, -, S, B, and A. S stands for switch, B and A are the two encoder outputs
• 1x Incremental rotary encoder: PEC11L-4220F-S0015-ND - http://www.bourns.com/PDFs/pec11l.pdf
• 3x 1k ohm resistors: Solder away!
• The input voltage (+) is rated up to (per datasheet) 10mA @ 5v DC. There are no current limiting resistors through S, B, and A - so if your application should require that, you will need to add them. We successfully tested 3.3V through this module + the Parallax Propeller with no problems.

Example Propeller Set-up (module is larger in picture for ease of view):

Demo PIC Code: Thanks to @chasxmd!: "I wrote some assembly code for the PIC 16F1509 (using TAUTIC’s 20 pin development board). It dumps a 8 bit counter to PORTC... you could easily drop this onto a DAC if you were looking for rotary encoder to voltage.. you’d have to stop the code at 0×00 and 0xFF so it doesn’t roll over/under though. The code is found at: http://iradan.com/?p=341."

The following is an example of what the serial terminal would look like with the demo code running:
