Forked in 2015 and modified for personal project
- Added acceleration support with
setAccel(boolean value)Meaning that the faster the encoder is rotated the greater the step of increment/decrement will be and keeping in mind that the encoder must be able to step by 1 if rotated slowly enough. Threshold time between steps is 150ms
Original library by mathertel
A Library for the Arduino environment for using a rotary encoder as an input.
Here you can find an Arduino compatible library for using rotary encoders.
I was searching a library for using a rotary encoder in my latest project and found a lot of information on this topic but none of the existing libraries did immediately match my expectations so I finally built my own.
The article on my web site explains the software mechanisms used in detail so you can understand the coding and might be able to adjust it to your needs if you like:

There are various aspects when writing a library for rotary encoders and you can also find a lot of the sources I analyzed at the bottom of this article.
