| ## Encoder The Wiring Encoder library allows for easily reading and writing a position or angle from an encoder. The encoders are sensors used to track the position or rotation rate of a shaft. Encoders generate pulses when moved, on each pulse triggering an event on the Wiring I/O board, for this reason the phaseA pin of an encoder can only be connected to a Wiring pin capable of generating external interrupts. The Encoder library works on pins 2, 3, 38 and 39, so only four encoders can be working at the a time. |  | Encoder() Class for manipulating encoders attached to the Wiring I/O board. attach() Attaches an encoder variable to an encoder connected to a pin. detach() detaches an encoder variable from a pin. read() Reads the encoder position or angle. write() Sets the encoder position or angle. attached() Returns whether or not en encoder is attached to a pin. |  |
