python和arduino的接口

我們正在連接ardiuno和python，並且我們需要在不同的時間間隔後把我們的信號從python發送到ardiuno，因爲我們用循環來發送數據和接收數據，但是我們不是從循環中獲取python的信號。但是，當我們使用相同的代碼，發送信號從python到ardiuno而不使用循環，它工作得很好。python和arduino的接口

如何使用的Arduino UNO

您使用Serial.end（從中讀取數據後，關閉的Arduino的串行端口）內使用它在循環循環功能。如果您刪除/註釋Serial.end（）語句，您將繼續接收Arduino串行端口上的數據。

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

而且，我相信你正在使用Python中pyserial庫串行通信（它使我們的生活變得更輕鬆）:)

讓我們知道，如果它的工作原理。
