Sense Hat tester

# Sense hat tester - change sense_hat to sense_emu to use the emulator

from sense_hat import SenseHat

sense = SenseHat()

b = (0, 0, 255)
r = (255, 0, 0)
g = (0, 255, 0)
y = (255, 255, 0)

sense.show_message("Colin was here", text_colour=r, back_colour = y)

#Added by John T
#you can use a web page for Trinket trinket.io/python/312a2b66ba
#The emulator will not display text_colour or back_colour as a pretty sparkle instead it displays black & white only
