/*######################### SMART BUTTON EXAMPLE ############################
This sketch gives a really basic example of how to send images to the Smart Button from NKK. The button
is just a basic button but the LCD screen is programmed with SPI. We use one of our smart switch boards
that uses an i2C to look for button presses and also send the control line to the smart switch. The smart
switch has a "selected" pin that needs to be high for the button to receive the data.
