####### NOTE ################
# This example is meant for use with Blinka/rasberry Pi due to the lack of analog pins.
# CircuitPython board users should run the "ds1841_simpletest.py" example

# WIRING:
# 1 Wire connecting  VCC to RH to make a voltage divider using the
#   internal resistor between RH and RW

# As this code runs, measure the voltage between ground and the RW (wiper) pin
# with a multimeter. You should see the voltage change with each print statement.
