# 扩展模块概要说明

Bittle 的嘴部被设计成一个夹子，可以用来固定可扩展的模块。 我们用一些流行的模块编译了一个传感器包，它的内容将来可能会发生一些变化。 基于 Arduino 和 Raspberry Pi 社区的丰富内容，您还可以连接其他附加组件。

您可以在我们的 GitHub 代码仓库中找到这些模块的演示代码。 如果您下载整个 OpenCat 代码仓，它们应该位于 [ModuleTests](https://github.com/PetoiCamp/OpenCat/tree/main/ModuleTests) 文件夹中。

响度传感器和亮度传感器模块可以为相应的模拟信号生成[读数](https://github.com/PetoiCamp/OpenCat/tree/main/ModuleTests/test_Loudness_Light)，应连接到 Grove 插座上的模拟端口。 &#x20;

触摸传感器、反射式光电传感器、PIR 传感器可以生成数字 1 或 0 作为开关信号。 所以它们应该连接到Grove 插座上的数字端口。 在[演示代码](https://github.com/PetoiCamp/OpenCat/tree/main/ModuleTests/test_Touch_Reflection_PIR)中，我们使用标有 D6 和 D7 的数字端口连接传感器。
