################ AnalogIn Example #####################
#
# This example shows how to use the AnalogIn class provided
# by the library by creating an AnalogIn instance and using
# it to measure the voltage at the first ADC channel input
#
# Wiring:
# Connect a voltage source to the first ADC channel, in addition to the
# normal power and I2C connections. The voltage level should be between 0V/GND and VCC
#
