# Makefile found at http://www.instructables.com/id/Honey-I-Shrunk-the-Arduino-Moving-from-Arduino-t/step2/Our-first-AVR-C-project-Hello-world-LED/
#
# The following modifications have been done:
#
# target fuse_flash will both flash chip and set fuses instead of sequential invocation of avrdude which causes problems on my system because the dragon
# reenumerates on the USB bus, second invocation takes place too fast. Using only one invocation of avrdude fixes this.
#
# Added .PHONY for targets that doesn't produce files
