byte m = 25 ;//用字节类型声明变量,并用25初始化它. int 整形是数字存储的主要数据类型。int 存储一个16位(2字节)的值范围是: -32,768到 32,767 (最小值为-2^15,最大值为(2^15)- 1)。在Arduino中 int 的大小会因开发板的不同而不同。例如,在Arduino Due上,int 存储一个32位(4字节)的值,...

byte Description A byte stores an 8-bit unsigned number, from 0 to 255.Syntax byte var = val;Parameter Values var: variable name. val: the value to assign to that variable.Example byte b = B10010; // "B" is the binary formatter (B10010 = 18 in decimal) ...
