# Lesson 06: Introduction to Arduino Data Types

This code is part of Lecture 06 Data Types: Integer

We learn how to define integers such as 0, 1, 2, 1000, 34500 etc.
Here is what we read on Arduino Official page Integers are your primary data-type for number storage. On the Arduino Uno (and other ATmega based boards) an int stores a 16-bit (2-byte) value. This yields a range of -32,768 to 32,767 (minimum value of -2^15 and a maximum value of (2^15) - 1). On the Arduino Due and SAMD based boards (like MKR1000 and Zero), an int stores a 32-bit (4-byte) value. This yields a range of -2,147,483,648 to 2,147,483,647 (minimum value of -2^31 and a maximum value of (2^31) - 1).
