Basic micropython library to read the distance from an ultrasonic sensor US-100 in serial mode

##############################################################################################

This library allows the micro:bit to read the distance from an ultrasonic sensor US-100 (Y401)).

It uses the serial port to communicate with the device and to retrieve both the distance and temperature. By default it assumes pin15 connected to trigger/tx and pin14 connected to echo/rx

Main features

=============

* Get the distance in mm from the sonar to an object.

* Get the temperture measured by the sensor.

* Sample program.

Library usage

=============

distance_mm()

+++++++++++++++++++++++

Get the distance in mm.

.. code-block:: python

   from us100 import US100

   from microbit import sleep

   sonar=US100()

   while True:

       print('%.1f' % (sonar.distance_mm()/10))

       sleep(1000)

temperature()

+++++++++++++++++++++++

Get the temperature from the sonar

.. code-block:: python

   from us100 import US100

   from microbit import sleep

   sonar=US100()

   while True:

       print('%i' % sonar.temperature)

       sleep(1000)
