Overview

The following sections below will go over how to control the LED array on your MATRIX Device.

Import Statement

from matrix_lite import led

led

.length

Returns the number of LEDs on a MATRIX device. 

led.length

.set()

Allows you to set the colors of each LED. A string, object, tuple or array can be given to this function.

led.set('blue') # color name
led.set('#0000ff') # hex values
led.set({'r':0, 'g':0, 'b':255, 'w':0 }) # object
led.set((0,0,255,0)) # tuple

Passing in an array allows you to set each individual LED color. However, passing an array that's larger than led.length will result in an error. 

led.set(['red', 'gold', (255,0,255,0), {}, 'black', '#6F41C1', 'blue', {'g':255}])

Everloop Examples
from matrix_lite import led
# A single string or object sets all LEDs
# Below are different ways of expressing the color blue (number values are from 0-255)
led.set('blue')
led.set('#0000ff')
led.set({'r':0, 'g':0, 'b':255, 'w':0 }) # objects can set white
led.set((0,0,255,0)) # tuples can set white

from matrix_lite import led
# Each line below is a valid way of turning the LEDs off
led.set('black')
led.set([])
led.set()
led.set({})

from matrix_lite import led
import time

everloop = ['black'] * led.length
everloop[0] = {'b':100}

while True:
    everloop.append(everloop.pop(0))
    led.set(everloop)
    time.sleep(0.050)

from matrix_lite import led
from time import sleep
from math import pi, sin

everloop = ['black'] * led.length

ledAdjust = 0.0
if len(everloop) == 35:
    ledAdjust = 0.51 # MATRIX Creator
else:
    ledAdjust = 1.01 # MATRIX Voice

frequency = 0.375
counter = 0.0
tick = len(everloop) - 1

while True:
    # Create rainbow
    for i in range(len(everloop)):
        r = round(max(0, (sin(frequency*counter+(pi/180*240))*155+100)/10))
        g = round(max(0, (sin(frequency*counter+(pi/180*120))*155+100)/10))
        b = round(max(0, (sin(frequency*counter)*155+100)/10))

        counter += ledAdjust

        everloop[i] = {'r':r, 'g':g, 'b':b}

    # Slowly show rainbow
    if tick != 0:
        for i in reversed(range(tick)):
            everloop[i] = {}
        tick -= 1

    led.set(everloop)

    sleep(.035)
