Inspired to improve my own Larson Style scanners by @zleap and maybe learn a little micropython. This is a M5Atom Matrix, with 25 neopixels, only using the first 5 for this. My code is rough at best, I'm not a python person, and made it work with what little I do know. Code below.

from time import sleep import machine, neopixel

NUMBER_PIXELS = 25 STATE_MACHINE = 0 LED_PIN = 27

strip = neopixel.NeoPixel(machine.Pin(LED_PIN), NUMBER_PIXELS) #(NUMBER_PIXELS, STATE_MACHINE, LED_PIN, "GRB")

Color RGB values

red = (255, 0, 0) red_med = (32, 0, 0) red_light = (8, 0, 0) off = (0,0,0)

delay = .06

for i in range(0, 5): strip[i] = (red_light) strip.write() sleep(.1)

for i in range(0, 5): strip[i] = (red_med) strip.write() sleep(.1)

for i in range(0, 5): strip[i] = (red) strip.write() sleep(.1)

for i in range(0, 5): strip[i] = (red_med) strip.write() sleep(.1)

for i in range(0, 5): strip[i] = (red_light) strip.write() sleep(.1)

while True: strip[0] = (red) strip[1] = (red_med) strip[2] = (red_light) strip[3] = (off) strip[4] = (off) strip.write() sleep(delay) strip[0] = (red_med) strip[1] = (red) strip[2] = (red_med) strip[3] = (red_light) strip[4] = (off) strip.write() sleep(delay) strip[0] = (red_light) strip[1] = (red_med) strip[2] = (red) strip[3] = (red_med) strip[4] = (red_light) strip.write() sleep(delay) strip[0] = (off) strip[1] = (red_light) strip[2] = (red_med) strip[3] = (red) strip[4] = (red_med) strip.write() sleep(delay) strip[0] = (off) strip[1] = (off) strip[2] = (red_light) strip[3] = (red_med) strip[4] = (red) strip.write() sleep(delay) strip[4] = (red_med) strip[3] = (red) strip[2] = (red_med) strip[1] = (red_light) strip[0] = (off) strip.write() sleep(delay) strip[4] = (red_light) strip[3] = (red_med) strip[2] = (red) strip[1] = (red_med) strip[0] = (red_light) strip.write() sleep(delay) strip[4] = (off) strip[3] = (red_light) strip[2] = (red_med) strip[1] = (red) strip[0] = (red_med) strip.write() sleep(delay) strip[4] = (off) strip[3] = (off) strip[2] = (red_light) strip[1] = (red_med) strip[0] = (red) strip.write() sleep(delay)
