There are several logical operators included in the Arduino programming language. These operators are the AND, OR and NOT operators. The NOT operator enables us to reverse a comparison operation. The AND and OR operators enable us to combine multiple comparison operators into one step. The following code shows how to use the logical operators:
(x > 5 && x < 10) // true if x is greater than 5 and less than 10 (x > 5 || x < 1) // true if x is greater than 5 or less than 1 !(x == y) // returns true if x is not equal to y
Now let's see how we can cast a variable.
