Note that theordfunction returns the value of the byte as an integer. Nonetheless, in Python, we cannot concatenate a string or a character to an integer. So, before we add the comma, we need to convert the value of the byte to a string using thestrfunction. Only then we can concaten...
也可以选择ZIP压缩包解压后，双击Arduino.exe直接进入IDE使用。具体安装过程，这里就不详细介绍了。
