==== 1. Bank Safe ====

=== Step ===

Connect a potentiometer to A0. Use the function //valRange = map(...)// to map the raw potentiometer values to the integer numbers 0..9 . The variable //varRange// can acquire these 10 different values.

Print the current value of //valRange// to the terminal, but only, if the value changes.
