That's all there is to getting started with CircuitPython and DotStar LEDs!

Below is an example that turns all 30 LEDs random colors. To use, download the file, rename it to code.py and copy it

to your board!

Full Example Code

import time

import random

import board

import adafruit_dotstar as dotstar

# On-board DotStar for boards including Gemma, Trinket, and ItsyBitsy

dots = dotstar.DotStar(board.APA102_SCK, board.APA102_MOSI, 1, brightness=0.2)

# Using a DotStar Digital LED Strip with 30 LEDs connected to hardware SPI

# dots = dotstar.DotStar(board.SCK, board.MOSI, 30, brightness=0.2)

# Using a DotStar Digital LED Strip with 30 LEDs connected to digital pins

# dots = dotstar.DotStar(board.D6, board.D5, 30, brightness=0.2)

# HELPERS

# a random color 0 -> 224

def random_color():

return random.randrange(0, 7) * 32

# MAIN LOOP

n_dots = len(dots)

while True:

# Fill each dot with a random color

for dot in range(n_dots):

dots[dot] = (random_color(), random_color(), random_color())

time.sleep(.25)
