# Firmware builder for BlinkyTape devices in PatternPaint
#
# To use this, you'll need to install Arduino (1.8.1 is current as of writing).
#
# You'll also need to add the following board support packages:
# * Blinkinlabs32u4 boards
#
# And the following libraries:
# * FastLED (available through the library manager)
# * BlinkyTape (download from https://github.com/Blinkinlabs/BlinkyTape_Arduino/releases)
#
# Note for Windows: you'll also need MinGW to run this script, as described in the PatternPaint readme.
