data types in our applications. While using different type of variables we may need to convert then to different types. In this tutorial we will different type of conversion from list to string in Python.
You can use the Arduino Software (IDE) serial monitor to view the sent data, or it can be read by Processing (see code below), Flash, PD, Max/MSP (see example below), etc. The examples below split the incoming string on the commas and convert the string into numbers again. 可以使用...

No, you typically convert a number to a string first and then usetoCharArray()to convert that string to a char array. What happens if the char array size is smaller than the string length? If the char array is smaller, it will not store the entire string, and you may encounter data ...
如果您按下在新窗口中打开的按钮,将会自动输入VenderID、ProductID和Serial Number。需要使通信速度与Arduino程序中设置的值相匹配。请从BaudRate的下拉菜单中选择57600bps。需要设置接收来自Arduino的数据的方法。请将“Read Protocol”设置为“Line Feed Data To String”。
