# Meant for use with the Raspberry Pi and an Adafruit monochrome OLED display!

# This program takes any image (recommended: landscape) and converts it into a black and white image which is then
# displayed on one of Adafruit's monochrome OLED displays.

# To run the code simply change directory to where it is saved and then type: sudo python OLEDimage.py <image name>
# For example: sudo python OLEDimage.py penguins900x600.jpg
