SignalTower#

Signal Tower commands can only be used with the CTE Signal Tower.

Initializing the SignalTower Class #

A Signal Tower is created by using the following constructor:

arm.signal_tower

This constructor uses no parameters.

# Construct a Signal Tower "signaltower_1" with the
# arm.signal_tower class.
signaltower_1 = arm.signal_tower

This signaltower_1 object will be used in all subsequent examples throughout this API documentation when referring to SignalTower class methods.

The set_color(color, state) method is used to set the Signal Tower’s color and state indefinitely, or until the method is used again.

Parameter	Description
`color`	A valid `SignalTowerColorType`.
`state`	A valid `SignalTowerStateType`.

Returns: None

# Set the Signal Tower to start blinking the blue LED.
