項(xiàng)目簡(jiǎn)介

1.功能詳解

STM32智能語(yǔ)音分類垃圾桶

功能如下：

1. STM32F103C8T6單片機(jī)系統(tǒng)板作為主控單元

2. 舵機(jī)驅(qū)動(dòng)垃圾桶蓋打開(kāi)與關(guān)閉

3. 按鍵控制四個(gè)分類垃圾桶的開(kāi)關(guān)

4. 語(yǔ)音識(shí)別控制分類垃圾桶開(kāi)關(guān)

5. 光電紅外傳感器監(jiān)測(cè)垃圾是否已滿，并指示燈提示

6. OLED顯示屏顯示分類垃圾桶開(kāi)關(guān)狀態(tài)

7. 手機(jī)藍(lán)牙APP接收分類垃圾桶已滿消息

2.材料清單
