# Arduino makefile
#
# This makefile allows you to build sketches from the command line
# without the Arduino environment (or Java).
#
# The Arduino environment does preliminary processing on a sketch before
# compiling it.  If you're using this makefile instead, you'll need to do
# a few things differently:
#
#   - Give your program's file a .cpp extension (e.g. foo.cpp).
#
#   - Put this line at top of your code: #include <WProgram.h>
#
#   - Write prototypes for all your functions (or define them before you
#     call them).  A prototype declares the types of parameters a
#     function will take and what type of value it will return.  This
#     means that you can have a call to a function before the definition
#     of the function.  A function prototype looks like the first line of
#     the function, with a semi-colon at the end.  For example:
#     int digitalRead(int pin);
#
# Instructions for using the makefile:
#
#  1. Copy this file into the folder with your sketch.
#
#  2. Below, modify the line containing "TARGET" to refer to the name of
#     of your program's file without an extension (e.g. TARGET = foo).
#
#  3. Modify the line containg "ARDUINO" to point the directory that
#     contains the Arduino core (for normal Arduino installations, this
#     is the hardware/cores/arduino sub-directory).
#
#  4. Modify the line containing "PORT" to refer to the filename
#     representing the USB or serial connection to your Arduino board
#     (e.g. PORT = /dev/tty.USB0).  If the exact name of this file
#     changes, you can use * as a wildcard (e.g. PORT = /dev/tty.USB*).
#
#  5. At the command line, change to the directory containing your
#     program's file and the makefile.
#
#  6. Type "make" and press enter to compile/verify your program.
#
#  7. Type "make upload", reset your Arduino board, and press enter  to
#     upload your program to the Arduino board.
