phillmybuttons:
...counting from 0.0ft to 10.6 ft ...
//example
switch (count){ //my generic switch code, counts up with button press

When count = 0, feet = 0. When count = 1, feet = 0.1. When count = 2, feet = 0.2. Time for our first expression...

float feet;

void loop( void )
{
...
  feet = count / 10.0;
...
}

Whenever you change count, recalculate feet using the expression above.
