Introduction

This project does a pretty simple task: it blinks between red and yellow in 0.3s intervals!

Components Needed

• A Little Python Brain
• A tablet/phone/computer

How To Build:

1. Connect to your Little Python Brain using a tablet
2. Go to the Blocks IDE
3. Import the neopixel, sleep, and Pin libraries
4. Set up the neopixel
5. Create your loop!
   • You can build your loop using a while True block or a while condition block. Use whatever you prefer!
   • Make sure to add a sleep(0.3) after each np.write()!
6. Run the code!

The Code

import neopixel
from time import sleep
from machine import Pin
np = neopixel.NeoPixel(Pin(12), 1)
while Pin(0, Pin.IN, Pin.PULL_UP).value():
np[0] = (102, 0, 0) # Colour = #660000
np.write()
sleep(0.3)
np[0] = (102, 102, 0) # Colour = #666600
np.write()
sleep(0.3)
