unsigned char

[Data Types]


An unsigned data type that occupies 1 byte of memory. Same as the byte datatype.

The unsigned char datatype encodes numbers from 0 to 255.

For consistency of Arduino programming style, the byte data type is to be preferred.


unsigned char var = val;


var: variable name.
val: the value to assign to that variable.

Example Code

unsigned char myChar = 240;
