奥特曼心率灯 · 心率传感器试用

实现的效果如上图.....

需要的东东
----------------------------
Arduino UNO*1
DF心率传感器*1
RBGLED模块*1
LC12S无线模块*1

本来打算使用DF的Bluno来实现心率同步的效果的,但困于ble的开发...
于是想到了之前用过的一款性价比极高的无线模块,LC12s某宝有卖
可以实现在同一频道下串口数据透传,那么为什么需要这么一个模块呢
这个项目除了心率的显示之外,还有一个遇到相同心率的人的时候爆闪的功能
Arduino在读取了心率的数据之后,同时会通过LC12s无线模块广播自身的心率值
同时也会接受频道内其他的心率值,遇到数值相同的时候,爆闪,好像挺酷的

1.首先,我们需要一个奥特曼外壳根据RGBLED大小来设计

大概的外形就是这样了

开打

然后用热熔胶固定一下LED模块就可以了

刷程序进去看看效果

视频演示效果(好像看视频没什么特别的饿...呃...紧张的那部分因为没有去跑步,改了一点数值来拍视频的....)
心率传感器的库里面的关于无效数值的这部分有时候会奇怪,而且模块要放在手上一段时间才会出数据,并且剧烈抖动的时候会比较不准
实际使用的时候,驱动可以自己写,或者直接读取模拟量,至于数值误差这部分,可以根据项目的需要进行过滤
