# BME280_Read_A Routine
# From BC-Robotics Tutorials (see Source at end)
# Just like the last sensor, we will import the library, set up the sensor, 
# read the sensor, and print the results. Since we are now using the Circuit 
# Python compatible libraries in this tutorial, there are a few extra chunks 
# of code to add.
#
# precede this program by the following Terminal commands:
# > $ sudo apt-get update
# > $ sudo pip3 install --upgrade setuptools
# > $ pip3 install RPI.GPIO
# > $ pip3 install adafruit-blinka
# > $ sudo pip3 install adafruit-circuitpython-bme280
# > $ sudo pip3 install adafruit-circuitpython-ads1x15
# no DS180B20
# > $ sudo apt-get install python3-w1thermsensor
# Preferences set to enable i2c and 1-wire
# Imports now succeed.....
