constrain()

Constrains a number to be within a range.

constrain(x, a, b);

x is the number to constrain, all data types a is the lower end of the range, all data types b is the upper end of the range, all data types

The function will return: x: if x is between a and b a: if x is less than a b: if x is greater than b

// EXAMPLE USAGE
sensVal = constrain(sensVal, 10, 150);
// limits range of sensor values to between 10 and 150
