title: Sending data from android to arduino rx-tx USB
body: <p>I have an arduino that controls a car, I need a compass to control the car automatically, unfortunately we could net get a compass (not in stock, no online shopping availble in my country)</p>
  
  <p>So the idea is this:</p>
  
  <p>I will get a compass running on android and feed the data using the USB connection to send a hex data (as a serial connection)</p>
  
  <p>I cann set tx/rx pins  on arduino, but i do not know the capabilites of android and whether i can actually manage this..</p>
  
  <p>The idea is simple, get the data from the app and send it through the USB as a serial connection, no need for feed back or anything, just plug in the tx/rx wires coming from the phone into the arduino pins and start receiving.
  How can I manipulate the USB in such a way? is it even possible?</p>
  
  <p>Searching on google just returns unwanted results like connecting android to PC/ADB/external flash.. thise are not usedul at all.</p>
