led

Module: led
Source: modules/led.py

The led module provides the Led class, a high-level wrapper around MicroPython’s neopixel library for the single WS2812 RGB LED on the nXPico M (GPIO23).

Color constants

The following module-level constants are defined as (r, g, b) tuples and used internally by the shortcut methods:

Constant	Value
RED	(255, 0, 0)
GREEN	(0, 255, 0)
BLUE	(0, 0, 255)
WHITE	(255, 255, 255)
YELLOW	(255, 255, 0)
CYAN	(0, 255, 255)
MAGENTA	(255, 0, 255)
ORANGE	(255, 128, 0)
OFF	(0, 0, 0)

Class Led

from led import Led

Led()

Initialises the LED on GPIO23 and sets it to off [0, 0, 0].

---

set_color(value: list) -> None

Set the LED to an arbitrary RGB color.

Parameter	Type	Description
value	list	A 3-element list [r, g, b] with values in the range 0–255.

Raises ValueError if:

• value is not a list of exactly 3 elements.
• Any element is not an int.
• Any element is outside the range 0–255.

led.set_color([255, 128, 0])   # warm orange

---

get_value() -> list

Returns a copy of the current color as [r, g, b].

color = led.get_value()   # e.g. [255, 128, 0]

---

Color shortcut methods

Each method calls set_color() with the corresponding constant.

Method	Color
red()	[255, 0, 0]
green()	[0, 255, 0]
blue()	[0, 0, 255]
white()	[255, 255, 255]
yellow()	[255, 255, 0]
cyan()	[0, 255, 255]
magenta()	[255, 0, 255]
orange()	[255, 128, 0]
off()	[0, 0, 0]

All return None.

Example

from led import Led

rgb = Led()

rgb.red()
rgb.set_color([0, 100, 200])
print(rgb.get_value())   # [0, 100, 200]
rgb.off()
