Largely a work in-progress, please add/edit as you learn the details.  Note that this page is documenting the NXT-Python v1.1 release (http://code.google.com/p/nxt-python/), not the NXT_Python v0.7 release which appears to have gone dormant (note hyphen vs underscore).

== Software Stack ==
The function of this module is to locate NXT brick(s). Returns an <code>nxt.bluesock.BlueSock</code> object for robots connected by Bluetooth and a <code>nxt.usbsock.USBSock</code> object for robot connected by USB, and throws <code>nxt.locator.BrickNotFoundError</code> if none can be found.

*** <code>next()</code> - Find the next brick in the sequence, returns the same thing as <code>find_one_brick()</code>.
 
** <code>find_one_brick()</code>
 
** <code>find_bricks(host=None, name=None)</code> - Find all the bricks in the area, returns a generator object <code>find_bricks</code>.

**UltrasonicSensor
 
The compass sensor is a digital sensor, and can be interfaced as if it were another digital sensor, such as the Ultrasonic sensor. This is not recommended as a long-term solution.
 
 
 
* Methods
 
**UltrasonicSensor(bot,port)
 
**get_sample() returns a value between zero and 180 depending on the heading of the sensor. There is a one-to-two ratio between degrees from due North and get_sample() values.
 
 
 
* Example
 
compass = UltrasonicSensor(bot, PORT_1) #declare the sensor plugged into port 1 "compass"
 
heading = compass.get_sample()*2 # get the current heading in degrees from due north
