                                        蓝牙控制摇摇棒

       经过三周的努力,蓝牙控制摇摇棒已经完成,在此过程中收获良多。选择这个题目的原因

是摇摇棒是很不错的一个玩具,再加上蓝牙的交互,可以随心所欲的控制摇晃的内容,趣味性

很强,这也是我选择做摇摇棒的一个原因。

           本设计本文介绍了一种以STC89C52RC单片机为主控制器,HC-05蓝牙模块作为数据传

 输媒介,利用人眼视觉暂留的原理设计的蓝牙控制的摇摇棒。摇摇棒在摇动过程中形成一个扇

 形平面,平面内可清晰显示文字、字母、图案。蓝牙作为一种新型的信息传送工具,具有无限

 传输、方便、快捷的优点。将蓝牙的这种特性运用到摇摇棒上,再结合摇摇棒本身可以在手挥

 式摆动下动态显示文字及图案的特性,使得摇摇棒具有更好的利用价值。在设计中,通过蓝牙

 无线透传,实现摇摇棒实时修改显示内容。

成果展示:

 蓝牙控制aap界面:

手机端主要采用上中下的列表式与选项卡式布局,可以从上到下清晰的展示已匹配或搜素到的蓝牙设备,分层位置清晰固定。底部为导航菜单栏,共有4个菜单功能选项,分别是终端操作,开关操作,切换显示和自定义显示。

          (1)终端操作也是整个手机端的主控界面,在此界面,实现蓝牙的开启与关闭,实现蓝牙设备的搜索与连接,实现基本指令的发送以及数据的接收。

(2)开关操作界面主要由16个红色开关按钮所组成,分别对应摇摇棒中的16个LED发光二极管,点击相应的红色开关按钮,则与之对应的LED法官二极管实现状态的改变。

(3)切换界面主要功能为控制摇摇棒程序中预置摇动的显示内容,预置的内荣为“四川工商电子信息工程学院通信二班”,“LOVE”与心形。通过此界面即可随意变换摇摇棒显示内容。如下图。

(4)自定义显示界面中可以通过手机键盘输入汉字,英文或则图案(由于用的是STC89C52RC芯片,存储空间有限,所以最多可以允许输入4个汉字大小)。并且可以对显示效果进行微调。如图下图所示。

       单片机系统程序采用 keil uVision4 软件编写          手机蓝牙控制app基于HBuilderX平台开发       

   点击 完整程序 可以获得 蓝牙控制摇摇棒相关资源
