Constrains a number to be within a range.
constrain(x, a, b)
x: the number to constrain, all data types
a: the lower end of the range, all data types
b: the upper end of the range, all data types
x is between
x is less than
x is greater than
sensVal = constrain(sensVal, 10, 150); // limits range of sensor values to between 10 and 150
