Note that it's possible to run example code without hardware on regular CPython - but instead of a lovely seven-segment rendering with neopixels you'll have RGB values for each neopixel printed out. See
For amore authentic experience, copy
display_all.py to a MicroPython-powered board, connect a Neo7Segment to it (Pin 17 by default) and execute the code.
import utime as time from neopixel import NeoPixel from machine import Pin neo = NeoPixel(Pin(17), 29, timing=True) neo7 = Neo7Segment(neo, 1) display_string = '1234567890.abcdef' for char in display_string: neo7.display(char, (0, 0, 1)) time.sleep_ms(250)
