python和arduino的接口

我们正在连接ardiuno和python，并且我们需要在不同的时间间隔后把我们的信号从python发送到ardiuno，因为我们用循环来发送数据和接收数据，但是我们不是从循环中获取python的信号。但是，当我们使用相同的代码，发送信号从python到ardiuno而不使用循环，它工作得很好。python和arduino的接口

如何使用的Arduino UNO

，这是我们的代码

int ra = 3; 
int ya = 4; 
int ga = 5;

int x2=0; 
int x=0; 
int led=10;

您使用Serial.end（从中读取数据后，关闭的Arduino的串行端口）内使用它在循环循环功能。如果您删除/注释Serial.end（）语句，您将继续接收Arduino串行端口上的数据。

参考https://www.arduino.cc/en/Serial/End

而且，我相信你正在使用Python中pyserial库串行通信（它使我们的生活变得更轻松）:)

让我们知道，如果它的工作原理。
