from blinkstick import blinkstick

username = "username"
password = 'password'

#No need to edit anything below this line

_URL = "https://mail.google.com/gmail/feed/atom"

bstick = blinkstick.find_first()

#This overriden class will automatically supply username and password for atom URL
class my_opener (urllib.FancyURLopener):
    # Override
    def get_user_passwd(self, host, realm, clear_cache=0):
        return (username, password)

def auth():
    '''The method to do HTTPBasicAuthentication'''
    opener = my_opener()
    f = opener.open(_URL)
    feed = f.read()
    return feed

```python
from blinkstick import blinkstick

# Find all connected BlinkStick devices
sticks = blinkstick.find_all()

print(f"Found {len(sticks)} BlinkStick device(s)")

# Set different colors on each device
colors = [(255, 0, 0), (0, 255, 0), (0, 0, 255)]
for i, stick in enumerate(sticks):
    color = colors[i % len(colors)]
    stick.set_color(red=color[0], green=color[1], blue=color[2])
    print(f"Device {i+1}: {stick.get_serial()} - Color set to RGB{color}")
```
