Modulus operator produces the remainder.Including arithmetic operators, relational operators, logical operators, increment and decrement operators, Assignment operators.Specifies what is to be done on the operands.Data on which the computation is performed.This can be done in Arduino through operands and operators. Sometimes we want to combine variables to product new values or solve mathematical formulas.

Please search from the web to find out how to declare the variable as a constant, what is the use of it and what will happen if you change the value of the constant. Instead of variables, we may also want to assign a fixed value to an identifier and don’t want to change its value anymore.
Using uninitialized variables in computations will give unexpected results, and thus should be avoided. A variable that has not been given a value is said to be uninitialized, and will contain some garbage value.A variable may be initialized in its declaration by using an equal sign followed by a value.variable type variable name1, variable name2, ….A declaration specifies a type, and contains a list of one or more variables of that type.Arduino is case-sensitive so radius, RADIUS, Radius, etc., are different.a letter (i.e., A to Z, and a to z), or.It tells the Arduino board the size of storage needed to store the dataĮxtended size variables for integer storage.width is the identifier (variable name).Variable name (the identifier of the variable).When declaring a variable, we can choose….
Before variables are used, all of them have to be declared. Necessary Information for Electronic TraineesĪ variable is a way of naming and storing a value for later use by the program, such as data from a sensor or an intermediate value used in a calculation.
