Digital Out

Introduction

The Digital Out 3-Wire device allows the EXP Brain to send a digital signal to an external component such as an LED, relay, or other electronic device. It can send a high signal (5 volts) or a low signal (0 volts).

This page uses dig_out as the example Digital Out device name. Replace it with your own configured name as needed.

Below is a list of available methods:

• set – Sets the signal level of a 3-Wire Digital Out port to high or low.

Constructor – Manually initialize and configure a Digital Out device.

• DigitalOut – Create a Digital Out device.

set

set sets the signal level of the selected 3-Wire Port.

Usage:
dig_out.set(boolean)

Parameter	Description
boolean	Whether to send a high or low signal: True sends a high signal (5V), and False sends a low signal (0V).

# Send out a low signal from dig_out
dig_out.set(False)

Constructor

Constructors are used to manually create DigitalOut objects, which are necessary for configuring a Digital Out device outside of VEXcode.

DigitalOut

DigitalOut creates a Digital Out device.

Usage:
DigitalOut(port)

Parameter	Description
port	The 3-Wire Port that the Digital Out device is connected to: On the EXP Brain – brain.three_wire_port.x where x is the number of the port. On a 3-Wire Expander – expander.a where expander is the name of the expander instance.

# Create a Digital Out device in Port A
dig_out = DigitalOut(brain.three_wire_port.a)
