555定时器原理图

Question 1

您的代码是一个很好的尝试，但最好与良好的做法保持一致。这是一个可以用作电路框架的代码，这里是如何创建新组件并将它们用作电路 CAD 编辑器中的组件，基于 Henry 制作的组件亨利·孟克。他使用的另一种解决方案是克劳迪奥·菲安德里诺能够放置二极管的标识符和组件的类型。

在 MWE 中，创建了两个 tikz 对象，可以将其放置并识别为原理图编辑器（如 proteus 或 eagle）中的组件，引脚将使用宏通过坐标名称进行识别coordinate；对于电路的绘制，我根据以下结构使用circuitikz 手册，重要的是构造代码以使其可读；每个宏都故意\draw分配了颜色（蓝色）的绘制选项，将其更改为其他颜色，以便您可以识别它们绘制了电路的哪些部分；您可以使用 TikzEdt 编辑器立即可视化您所做的每个更改。

我支持你的问题，因为关于这个问题只有 2 个问题，也许可以鼓励很多人选择 tikz 的强大功能。
