How to Use Word() Function in Arduino?

The word() function converts a variable of any data type to the word data type. It is essentially a cast function.

Syntax

The syntax is −

word(var)

Where var is a variable of any datatype.

Alternatively, you can also construct a word by specifying two bytes, the higher byte and the lower byte.

Syntax

The syntax is −

word(highByte, lowByte)

For instance, word(2,5) will return 517 (2 is 0b00000010 and 5 is 0b00000101; word(2,5) will return 0b0000001000000101, which equals 517).

You can try out other combinations of characters and data types. You can read more about the word function from Arduino’s official documentation here.
