基于Arduino的蓝牙智能小车(代码+APP+教程)

ID:225013 · 发表于 2019-1-24 16:43

以arduino为主控板，包含电机驱动模块、蓝牙模块、语音模块、超声波模块、语音模块。实现前进后退左转右转（语音同步提醒），蓝牙APP所有按钮无障碍切换。

一.首先选择我们需要使用的APP

二.进入APP选择JDY-08设备

三，进入主界面操作

Arduino小车接收到相关的操作指令：
前进---- 0xa
后退----0xb
左---- 0xc
右--- 0xd
停止----0x10
音量+ ----0x11
音量- -----0x12
循迹----0xe
跟随---0x13
娱乐—0xf

Arduino源程序如下:
