Using 3-Wire Digital In/Digital Out Devices – VEX Library

VEXcode V5 has a 3-wire Digital In device and a 3-wire Digital Out device.

What Is Digital In/Digital Out

Digital Input: A digital input detects if a voltage is above/below of a specific threshold. If the voltage is higher, the V5 Robot Brain will detect the digital input as high. If the voltage is lower, the V5 Robot Brain will detect the digital input as low.

Digital Output: A digital output allows you to control a voltage with the V5 Brain. If the V5 Brain instructs the output to be high, the output will produce a 5 volt voltage. If the V5 Brain instructs the output to be low, it outputs no voltage.
