Lighting Groups Of Pixels
The functions in this first set are pretty basic. I use these as
indicators when trying to get the robot to respond to its sensors.
from microbit import *
import neopixel
# Initialise neopixels
npix = neopixel.NeoPixel(pin13, 12)
# Define some colours
red = (255,0,0)
green = (0,255,0)
blue = (0,0,255)
nocol = (0,0,0)
# light all neopixels with given colour
def LightAll(col):
for pix in range(0, len(npix)):
npix[pix] = col
npix.show()
return
# light neopixels on the left fin
def LightLeft(col):
for pix in range(0, 6):
npix[pix] = col
npix.show()
return
# light neopixels on the right fin
def LightRight(col):
for pix in range(6, 12):
npix[pix] = col
npix.show()
return
while True:
# All red
LightAll(red)
sleep(2000)
# Clear all
npix.clear()
sleep(1000)
# Light left pixels green
LightLeft(green)
# Light right pixels blue
LightRight(blue)
sleep(2000)
# Clear left
LightLeft(nocol)
sleep(1000)
# Clear right
LightRight(nocol)
sleep(1000)
