  # 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.
