Description: Code for an arduino microcontroller that automates an electromechnical dogfeeder by controlling:
1)An 20x4 LCD screen and rotary encoder for user input
2)An I2C backpack for the LCD screen
3)A 12V DC motor that powers an auger that dispenses feed out of the device
4)A servo motor that is connected to a door on the front of the box(that covers the auger hole) by a pushrod.
5)An IR sensor to read the height of dogfood in the feeders hopper. This measurement is used to approximate the remaining food in the device
6)A AS5040 analog encoder to determine the total rotation of the auger. This rotation is used by the microcontroller so that the user can set precise feed volumes through the menu.
7)A DS3231 RTC clock for precise time keeping. This allows the user to set feed times for dog food to be automatically dispensed
Libraries Used
1)AS5040 http://madscientisthut.com/forum_php/viewtopic.php?f=11&t=17 by "John"

Installation
1)Place the libraries in the arduino's libraries folder then either
2.a)BUILD IN VISUAL STUDIO i)Open the solution
ii)Using the ARDUINO IDE for Visual Studio Extension, add the libraries used (The ones located in the libraries used folder) using the add libraries button on the top toolbar
iii)Ensure Arduino is connected and the right com-port is selected in the top tool bar iv)build
2.b)BUILD IN ARDUINO IDE
i)Either copy paste the AutomatedFeeder.ino text into a sketch using a)The arduino to open the solution b)Github to open the file as text
ii)Copy and paste the header files and cpp files for "AS5040" and "menu" into your sketch folder
iii)compile->send to arduino
