Python / Mac OS X

revsin · June 2014

Nothing fancy, but just sharing what I've done with my blinkytape since I got it last Thursday. You'll notice that some of this code is redundant, but was just playin around with Python and seeing what I could come up with.


from BlinkyTape import BlinkyTape
import urllib2
import re
from time import sleep
import random
import math

from datetime import datetime
now = datetime.now()
hour = int(now.hour)
min = int(now.minute)

if int(hour) > 12:
	hour = int(hour) - 12
	

bb = BlinkyTape('/dev/tty.usbmodem1441') #least on Mac OS X, this is the port to use!

			bb.sendPixel(r,g%25,g%255)
		bb.show()

	for y in (range(60)):
