Arduino Controller android app

Hello Marque

First of all i would like to thank you for this great application you have no idea how helpful it is with my project, to begin with my project is a multi-axis sun tracking system that uses mathematical models to calculate the suns position and then send the servo motors to the the calculated angles. The program starts with a simple user interface where it asks the user to enter the location as (Longitude/ latitude) then the date and time, this is done by using an attached keypad and an lcd screen. To not take any longer of your time here is my question can i use the arduino application as the other alternative for the data input and for feed back; for example i can add a temperature sensor and use it for feedback in case of extreme temperatures, if this is possible please let me know how and also i would like to know what level of programing it needs because am still a beginner and have limited information on arduino programing. Thank you very much and i appreciate you work.
