New Dobsonian go-to indicator using an Arduino UNO. Uses 2 I2C connected AS5048B Magnetic rotary sensors/encoders, 1 2x16 LCD shield (DFR0009 by DFRobot.com) which includes buttons, and 1 DS1302 real time clock module. Also needs the DS1302RTC library from http://playground.arduino.cc/Main/DS1302RTC and the Time library from http://playground.arduino.cc/Code/Time or http://www.pjrc.com/teensy/td_libs_Time.html or https://github.com/PaulStoffregen/Time
