Code Overview, Compile and run
This time as we use the potentiometer it will require us to do some manual action,
But turning the potentiometer either right or left it will turn the value, higher or lower.
By doing so we can control multiple things such as brightness of LED's etc ... try to turn it around and see the value
changing.
Compile the script by going into the samples directory and running: python3 pcf8591.py
