Hardware Preparation

1. Mu editor supports Windows x64, Mac OSX, Linux operating systems, prepare a computer running one of these operating systems.

2. A development board that supports CircuitPython, such as BPI-PicoW-S3.

3. A USB cable that can connect the development board to the computer.

Download and install Mu Editor

1. Open the Mu editor web page and click the Download button to enter the new page.

Edit code.py to make the lights blink

1. Click the Load button, select the code.py file on the CircuitPython development board, and click Open to start editing code.py .

2. Enter the following code in the editor:

import time
import board
import neopixel

pixels = neopixel.NeoPixel(board.NEOPIXEL, 1, brightness=0.1)

while 1:
    pixels[0] = (255,0,0)
    pixels.show()
    time.sleep(0.5)
    pixels[0] = (0,255,0)
    pixels.show()
    time.sleep(0.5)
    pixels[0] = (0,0,255)
    pixels.show()
    time.sleep(0.5)
    pixels[0] = (255,255,255)
    pixels.show()
    time.sleep(0.5)

3. Click the Save button, and the edited content will be saved to the CircuitPython development board.

If the code is correct, the full color LED on the development board will twinkle red, green, blue, and white cyclically.
