Class DigitalInput

java.lang.Object
edu.wpi.first.wpilibj.DigitalInput
All Implemented Interfaces:
Sendable, AutoCloseable
public class DigitalInput extends Object implements AutoCloseable, Sendable
Class to read a digital input. This class will read digital inputs and return the current value on the channel. Other devices such as encoders, gear tooth sensors, etc. that are implemented elsewhere will automatically allocate digital inputs and outputs as required. This class is only for devices like switches etc. that aren't implemented anywhere else.
