Double

Is the double implementation is exactly the same as the float

Float

Is a number that has a decimal point

Unsigned

An unsigned data type that occupies 1,2 and 32 byte of memory

Long

Are extended size variables for number storage, and store 32 bits 

Word

 This action stores a 16-bit unsigned number

Int

This function integers are your primary data-type for number storage.

Byte

This action stores an 8-bit unsigned number, from 0 to 255.

Char

This means that it is possible to do arithmetic on characters

Void

 Is used only in function declarations

Enter Constans

Are numbers used directly in a sketch, like 123

True-False

Is used to deine 0 and 1 (respectly)

Input-Output

Is useful to reading a sensor and powering LEDs (respectly)

High-Low

The meaning of high an low have a different meaning depending on whether a pin is set to input or output

left bit shift, right bit shift

These operators cause the bits in the left operand to be shifted left or right by the number of positions specified by the right operand.

bit a bit x or

Is used to evaluates to 0 for a given bit position when both of the input bits

bit a bit or

Like the bit a bit AND operator, this operates independently each bit in its two surrounding integer expressions

bit a bit AND

Is a single ampersand, used between two other integer expressions.

Modul

This action calculates the remainder when one integer is divided by another. It is useful for keeping a variable within a particular range

Addition, Substraction, Multiplication, Division

These operators return the sum, difference, product, or quotient (respectively), are valors of the arithmetic

Include

This action is used to include outside libraries in the sketch

Define

Is a useful component that allows give a name to a constant value
