# Arduino核心库函数

- [必备函数](https://arduino.doc.skyone.host/core/base.md): 想要写一个Arduino程序，这些函数是必须的。
- [引脚控制](https://arduino.doc.skyone.host/core/io.md): 实现引脚控制是单片机程序的最简单最基本的功能
- [pinMode](https://arduino.doc.skyone.host/core/io/pinmode.md): 定义引脚模式
- [digitalWrite](https://arduino.doc.skyone.host/core/io/digitalwrite.md): 控制引脚的输出
- [digitalRead](https://arduino.doc.skyone.host/core/io/digitalread.md): 读取引脚的电位
- [analogWrite](https://arduino.doc.skyone.host/core/io/analogwrite.md): 控制引脚的输出
- [analogRead](https://arduino.doc.skyone.host/core/io/analogread.md): 读取引脚的电压
- [时间相关](https://arduino.doc.skyone.host/core/time.md): 控制时间也是非常重要滴
- [delay](https://arduino.doc.skyone.host/core/time/delay.md): 延时一定毫秒
- [delayMicroseconds](https://arduino.doc.skyone.host/core/time/delaymicroseconds.md): 延时一定微秒
- [millis](https://arduino.doc.skyone.host/core/time/millis.md): 获取 "Arduino时间"，而不是 UNIX时间
- [micros](https://arduino.doc.skyone.host/core/time/micros.md): 获取 "Arduino时间"，而不是 UNIX时间
- [串口通信](https://arduino.doc.skyone.host/core/serial.md): 串口通信是Arduino debug的最常用的手段
- [begin](https://arduino.doc.skyone.host/core/serial/begin.md): 使用串口之前，必须先初始化串口
- [print](https://arduino.doc.skyone.host/core/serial/print.md): 向串口写入数据，使我们在电脑上能看到Arduino的运行状态
- [read](https://arduino.doc.skyone.host/core/serial/read.md): 从串口获取数据，这样我们就能通过串口实时向Arduino发送命令
- [其它方法](https://arduino.doc.skyone.host/core/serial/other.md): 这是一些其他的常用的串口函数

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://arduino.doc.skyone.host/core.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
