# Final Project ITCS2875 Computer Architecture & Organization
#
# Description: "Solve a humanitarian issue using electrical
# components and a Raspberry Pi"
#
# Using a Servo-Motor, LED, and a button,
# this program is used to rotate the top plate
# of a custom design circular pill container. The user is to 
# interact with the box by simply pressing a button and 
# referring to the LED as an indicator of whether the medication
# was taken or not. With each button press, the box rotates 
# through each day of the week and runs until the user either
# disconnects the power from the pi or can manage to end the
# program through the GUI of the IDE. No monitor output is
# required to use this box as the simplicity is what makes it
# most user friendly for people of all ages and abilities.
#
#
# INPUT: The program seeks input from the GPIO ports on the pi
# along with waiting for the user to interact with the button.
#
# PROCESSING: Upon button press, the LED indicator is turned off
# and the timer is set until the user has to be reminded to take
# their medication again given a set sleep window embedded into
# code from there, the LED will turn back on and wait for the user
# to interact with the button.
#
# OUTPUT: The outputs of this program are the power state of
# the LED being on or off and the rotational positioning of
# the servo-motor revealing or concelaing the sections of the
# container/box.
