The encoder used is a mechanical encoder with 24 pulses-per-revolution (PPR). High PPR encoders provide more precise positioning information. However, this example uses it for user interfacing, where the precision of a higher PPR encoder was not needed.

To connect the encoder to the microcontroller, the manufacturer for this encoder (Bourns Inc.) recommends pulling up the outputs of the encoders to Vdd and filtering with an RC filter, an example of which is shown in Figure 3. (See the [Manufacturer's Datasheet](https://www.bourns.com/docs/Product-Datasheets/PEC12R.pdf) for up-to date information.)
