字符串转数字 String To Int 可以使用 atoi 函数将字符串转换为整数。例如: highlighter- Arduino String str = "12345"; int num = atoi(str.c_str()); // num 的值为 12345 另外,也可以使用 sscanf 函数将字符串转换为指定类型的数字。例如: highlighter- Arduino String str = "123.45"; float num;...

在开始使用Arduino之前，需要下载Arduino IDE进行安装，下载地址是 https://www.arduino.cc/en/Main/...

Basically, we can send and receive data as bytes or strings to the Arduino via its USB connection. I used strings since we can always cast these to anything else like numbers in Arduino and Small Basic.You could use any convention for your data, but you will need an event (LDCommPort....
