# 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.
