Galactic Unicorn: How to Turn on a Single LED

Discussion Raspberry Pi

Using micropython…

Does anyone have an example of how to blink, for example LED at position 5,5 with a BLUE color?

TIA

It’s display.pixel to set individual pixels - more info in the PicoGraphics docs!:

Give this a try.

from galactic import GalacticUnicorn
from picographics import PicoGraphics, DISPLAY_GALACTIC_UNICORN
import time

display = PicoGraphics(display=DISPLAY_GALACTIC_UNICORN)
gu = GalacticUnicorn()
gu.set_brightness(0.5)

BLACK = display.create_pen(0, 0, 0)
BLUE = display.create_pen(0, 0, 255)

while True:
        
    display.set_pen(BLUE)
    display.pixel(5, 5)
    gu.update(display)
    time.sleep(1)

    display.set_pen(BLACK)
    display.pixel(5, 5)
    gu.update(display)
    time.sleep(1)

Wow, that was fast. =)
I happen to have one to test code on. Saves the guessing. ;)
