Jo highVoltage brought her lego scene to life using her CPX, a Crickit, a continuous servo, a NeoPixel strip and an external speaker.  This project is coded in CircuitPython.

The video shows how the project was made.

 

Here is the CircuitPython code for this project:

import time
import board
import digitalio
from adafruit_crickit import crickit
import neopixel
import audioio

num_pixels = 30   # Number of pixels driven from Crickit NeoPixel terminal
pixels = neopixel.NeoPixel(board.A1, num_pixels,
brightness=0.3, auto_write=False)
RED = (204, 51, 0)
YELLOW = (255, 255, 102)
GREEN = (10, 204, 10)
GREY = (102, 153, 153)
BROWN = (153, 51, 0)
GOLD = (255, 204, 0)
BLUE = (0, 0, 204)
GRAY = (102, 133, 153)

wave_file = open(“HarryP.wav”, “rb”)
wave = audioio.WaveFile(wave_file)
audio = audioio.AudioOut(board.A0)

buttonA = digitalio.DigitalInOut(board.BUTTON_A)
buttonA.direction = digitalio.Direction.INPUT
buttonA.pull = digitalio.Pull.DOWN
