【一起diy】AI智能垃圾分类箱

【一起diy】AI智能垃圾分类箱

1、前言

感谢DF的粒子邮寄过来的人工智能三剑客中的两剑客：中英文语音合成模块和I2C语音识别模块。于是做什么项目呢？
上海在2019年7月1号起已经开始实行强制垃圾分类，实行了垃圾分类的政策，主要原因是随着人们生活水平的提高，各类消费增加，产生了大量的垃圾，如果不能够合理处理这些垃圾，将严重污染环境，为了解决这个问题，响应国家提出的垃圾分类政策，保护我们赖以生存的家园。用掌控板结合中英文语音合成模块和I2C语音识别模块来做一个AI智能垃圾分类箱！

2、材料清單

数量	硬件名称
1	掌控板
1	掌控宝
1	I2C语音识别模块
1	中英文语音合成模块
4	9G 舵机
1	激光切割键若干

3、硬件介绍

2.1语音识别模块
该模块采用由 ICRoute 公司设计的 LD3320 “语音识别”专用芯片，只需要在程序中设定好要识别的关键词语列表并下载进主控的MCU中，语音识别模块就可以对用户说出的关键词语进行识别，并根据程序进行相应的处理。本品不需要用户事先训练和录音就可以完成非特定人语音识别，识别准确率高达95%。

详细资料可以看一下产品wiki

2.2语音合成模块

支持中文、英文和中英文混合合成、自带喇叭、Gravity I2C/UART双通讯、支持多种主控板，arduino、micro:bit、掌控板等。语音合成功能支持多种文本控制标记，可以满足用户对语音合成发音人、音量、语速、语调等的设置。更新详细说明可以查看产品wiki

4、电路连接

**注：**在使用舵机时，为了对称本来使用的P5硬件来驱动一个舵机，单独调试运行的时候发现不能驱动。于是换了P0,P3,P6,P7,P11都不行，有时引脚设置后会导致原本正常的引脚BUG。可能是引脚占用的原因。于是就换成了P14引脚。

5、程序设计

打开mind+ 在‘上传模式’下，点击“扩展”选择掌控板后，然后添加用户库搜索ext 然后选择中英文语音合成模块和I2C语音识别模块。

然后开始对项目进行编写。
