Int vs Byte
When working with microcontrollers like Arduino, understanding data types is crucial. Two of the most commonly used data types in Arduino are int vs byte. In this article, we will explore the differences between
byte in Arduino and provide a comparison table to help you choose the right data type for your project.
What are int and byte data types in Arduino?
int is short for “integer,” which is a whole number that can be positive, negative, or zero. In Arduino, an
int data type is a 16-bit (2-byte) signed integer. This means that it can hold values between -32,768 and 32,767.
int is typically used to store values that require more than 8 bits of memory.
On the other hand,
byte is a data type that can hold an 8-bit (1-byte) unsigned integer. This means that it can hold values between 0 and 255.
byte is typically used to store values that require less than 8 bits of memory.

Differences between int and byte in Arduino
- Memory usage: The main difference between
byteis the amount of memory they use. An
inttakes up 2 bytes of memory, while a
bytetakes up only 1 byte of memory. This means that if you need to store a large number of values, using
bytecan help conserve memory.
- Range of values: Another difference between
byteis the range of values they can hold. An
intcan hold values between -32,768 and 32,767, while a
bytecan hold values between 0 and 255. This means that if you need to store values that are outside the range of a
byte, you must use an
- Operations: The operations that can be performed on
byteare also different.
intcan perform all the standard mathematical operations such as addition, subtraction, multiplication, and division.
byte, on the other hand, can only perform addition and subtraction. If you need to perform more complex mathematical operations, you must use an
|Data Type||Memory Usage||Range of Values||Operations|
|2 bytes||-32,768 to 32,767||Addition, subtraction, multiplication, division|
|1 byte||0 to 255||Addition, subtraction|
In conclusion, understanding the differences between
byte data types in Arduino is essential for creating efficient and effective projects. While
int is used for storing larger values and performing complex mathematical operations,
byte is used for storing smaller values and conserving memory. Use the comparison table to help you choose the right data type for your project, and remember to optimize your code for memory usage whenever possible.
