I am new to andriod and arduino programming, just recently got an arduino. My project is basically an andriod phone that is programmed to get input to turn on any of the three leds on the arduino. I will send the data based on the persons input and forward the information to a file in dropbox or googledrive. This will sync with the pc, where my pc will continually check the file and send commands to bluetooth on the arduino. Is there a better way to do this, as I am not sure which language should i use to check the file synced in dropbox to communicate from pc to arduino, should it be matlab or java.
