If you do need to work with a String class, you need to make an array of characters, as shown here: char name[5] = {'j', 'o', 's', 'h', 0}; or char name[] = "josh"; If you need to, for example, store multiple strings in an array, you can create an array with ...
SKIP_ALL: all characters other than digits or a minus sign are ignored when scanning the stream for an integer. This is the default mode. SKIP_NONE: Nothing is skipped, and the stream is not touched unless the first waiting character is valid. ...

action_servo = saved_data[Play_action] / 1000; //The fist character of the array element is split for knowing the servo number action_pos = saved_data[Play_action] % 1000; //The last three characters of the array element is split to know the servo postion ...
array void 数据类型转换: char() byte() int() long() float() 常量:HIGH | LOW 表示数字IO口的电平,HIGH 表示高电平(1),LOW 表示低电平(0)。 INPUT | OUTPUT 表示数字IO口的方向,INPUT 表示输入(高阻态),OUTPUT 表示输出(AVR能提供5V电压 40mA电流)。
Finally, we will iterate through all the characters of the string and print the corresponding byte value. To obtain the byte value of a character, we can use theordfunction. To make our life easier when copying the bytes to the Arduino code, we will append a comma after each byte. That...
37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
