Sensor de luz

Introducción

El Sensor de Luz mide la intensidad de la luz reflejada o incidida sobre un objeto. Emite un valor analógico que representa la cantidad de luz detectada.

This page uses light_sensor as the example Light Sensor name. Replace it with your own configured name as needed.

A continuación se muestra una lista de los métodos disponibles:

• brightness – Returns the amount of light detected by the Light Sensor as a percent.

• changed – Registers a function to be called whenever the Light Sensor’s brightness value changes.

Constructor – Inicializa manualmente un sensor de luz.

• Light – Create a Light Sensor.

brillo

brightness returns the amount of light detected by the Light Sensor as an integer. This can be used to check if an object is bright enough to accurately report other visual data.

Usage:
light_sensor.brightness(units)

Parámetro	Descripción
units	Optional. The unit to return the brightness with: PERCENT (default).

cambió

changed registers a function to be called whenever the Light Sensor’s brightness value changes.

Usage:
light_sensor.changed(callback, arg)

Parámetros	Descripción
callback	Una función previamente definida que se ejecuta cuando cambia el valor de brillo del sensor de luz.
arg	Optional. A tuple containing arguments to pass to the callback function. See Functions with Parameters for more information.

def my_function():
  brain.screen.print("Brightness changed")

# Call my_function whenever the brightness changes
light_sensor.changed(my_function)

Constructor

Constructors are used to manually create Light objects, which are necessary for configuring a Light Sensor outside of VEXcode.

Light

Light creates a Light Sensor.

Usage:
Light(port)

Parámetro	Descripción
port	The 3-Wire Port that the Light Sensor is connected to: On the V5 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 Light Sensor in Port A
light_sensor = Light(brain.three_wire_port.a)
