arduino/analog_shield/read_pot/main.py

Prints the potentiometer's (RV1) reading ten times a second. A5 reads up to 2.048 V, so with VIO at 3.3 V the last third or so of the turn reads full scale.

Uses

analogRead(A5), delay()

# Prints the potentiometer's (RV1) reading ten times a second, 0-1023.
#
# RV1 goes from 0 V to VIO (JP3) and is read on A5, where 1023 is 2.048 V:
# with VIO at 3.3 V, the last third or so of the turn reads 1023.
