datatypes in arduino

In Arduino, there are various data types used for different purposes:

  1. int: It is a signed integer type that stores values from -32,768 to 32,767.

  2. unsigned int: This is an unsigned integer type that stores values from 0 to 65,535.

  3. long: It is a signed long integer type that stores values from -2,147,483,648 to 2,147,483,647.

  4. unsigned long: Similar to the unsigned int, it is an unsigned long integer type that stores values from 0 to 4,294,967,295.

  5. byte: It is an unsigned 8-bit data type that can store values from 0 to 255.

  6. char: It is a data type used to store characters. It can hold a single character like 'a', 'b', 'c', etc., and is often used to represent ASCII characters.

  7. float: This data type is used to store floating-point numbers, which include decimals. It can store values from approximately 3.4028235E+38 to 3.4028235E+38 with seven decimal digits of precision.

  8. double: It is a double-precision floating-point number that can hold larger values than a float, with approximately 6 decimal places of precision.

These data types are used in Arduino programming to declare variables and perform various operations based on the type of data being handled.
