* OPEN-SMART Rich Shield Lesson 10: Measure voltage and Display
* You can learn use the 4-digit tube to display the input voltage value you measure.
*
* The following functions are available:

* voltage.read();//read the voltage and return a floating-point value

* disp.init(); // initialization
* display(double Decimal);// display a floating-point value
