python 程序发送的 RGB 数据未被 arduino 接收
RGB data sent from python program not recieving right by arduino
我正在研究 Twitter 情绪灯，并且有 arduino 和 python 代码。在丢失了我所有的 python 代码后，它不得不从内存中重新制作它，但我遇到了一些问题。 python 代码正在向 arduino 发送 rgb 数据以更改 rgb led 的颜色。但出于某种原因，arduino 没有获取最后一个值，而是将第二个值更改为蓝色 LED。
例如：我发送 50,50,50，它是暗白色，LED 显示紫色（蓝色和红色），如果我发送 0,0,255（蓝色亮起），它保持空白，如果我发送 0,255 ,0（绿色开启）它显示蓝色。
我不知道我已经尝试了这么多方法来让它工作。
Python代码：
我知道我发送了两次数据，这是发送功能工作的唯一方式

所有这些代码都是根据其他代码编辑或基于它的，所以有些注释在 python 程序中没有什么意义
