【心率传感器试用】+奥特曼心率灯 |
本帖最后由 nicho 于 2016-12-8 11:01 编辑 实现的效果如上图..... @DFRobot @luna 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 下面的代码是常规写法的DIGITAL_MODE [mw_shl_code=c,true]#define heartratePin A1 #define LED_R 9 #define LED_G 10 #define LED_B 11 #define LC12s_init_pin 5 #include "DFRobot_Heartrate.h" DFRobot_Heartrate heartrate(DIGITAL_MODE); ///< ANALOG_MODE or DIGITAL_MODE char inputString; // a string to hold incoming data boolean stringComplete = false; // whether the string is complete void setup() { pinMode(LED_R, OUTPUT); pinMode(LED_G, OUTPUT); pinMode(LED_B, OUTPUT); pinMode(LC12s_init_pin, OUTPUT); digitalWrite(LED_G, LOW); digitalWrite(LED_R, LOW); digitalWrite(LED_B, LOW); digitalWrite(LC12s_init_pin, HIGH); Serial.begin(9600); // reserve 200 bytes for the inputString: //inputString.reserve(200); delay(500); LC12s();//无线模块初始化 } void loop() { uint8_t rateValue; heartrate.getValue(heartratePin); ///< A1 foot sampled values rateValue = heartrate.getRate(); ///< Get heart rate value if(rateValue) { Serial.println(rateValue); //rateValue分级 LEDMode(rateJudge(rateValue)); delay(20); } if (inputString==rateValue) {//遇到相同频率的心跳信号的时候执行 LEDMode(5); } } int LC12s() {//初始化LC12s模块 char initCode[] = {0xAA,0X5A,0X22,0X33,0X11,0X21,0X00,0X00,0X00,0X04,0X00,0X64,0X00,0X00,0X00,0X12,0X00,0X05}; digitalWrite(LC12s_init_pin, LOW);//拉低set引脚进行组网操作 delay(100); for(int i=0; i<17; i++){ Serial.print(initCode); } delay(100); digitalWrite(LC12s_init_pin, HIGH); delay(500); } void LEDMode(int rateLevel) { switch (rateLevel) { case 0: // do something digitalWrite(LED_R, LOW); digitalWrite(LED_B, LOW); digitalWrite(LED_G, HIGH);//green break; case 1: // do something digitalWrite(LED_G, LOW); digitalWrite(LED_R, LOW); for(int i=0;i<5;i++) { for(int i=0;i<255;i++) { analogWrite(LED_B, i); delay(10); } for(int i=255;i>0;i--) { analogWrite(LED_B, i); delay(10); }} break; case 2: // do something digitalWrite(LED_R, LOW); //digitalWrite(LED_B, HIGH); //digitalWrite(LED_G, HIGH);//bule&green for(int i=0;i<5;i++) { for(int i=0;i<255;i++) { analogWrite(LED_B, i); analogWrite(LED_G, i); delay(3); } for(int i=255;i>0;i--) { analogWrite(LED_B, i); analogWrite(LED_G, i); delay(3); }} break; case 3: // do something digitalWrite(LED_G, LOW); digitalWrite(LED_B, LOW); //digitalWrite(LED_R, HIGH);//red for(int i=0;i<5;i++) { for(int i=0;i<255;i++) { analogWrite(LED_R, i); delay(1); } for(int i=255;i>0;i--) { analogWrite(LED_R, i); delay(1); }} break; case 4: // do something break; case 5: //当遇到心跳频率一样的信号的时候执行 for(int i=0; i<5 ; i++){ for(int i=0;i<255;i++) { analogWrite(LED_R, i); analogWrite(LED_G, i); delay(1); } for(int i=255;i>0;i--) { analogWrite(LED_R, i); analogWrite(LED_G, i); delay(1); } } break; default: // do something break; } } int rateJudge(int rateVal) {//心跳频率分级 if(rateVal<=30){ return 0; } if(rateVal>30&&rateVal<60){ return 1; } if(rateVal>=60&&rateVal<=80){ return 2; } if(rateVal>80&&rateVal<=110){ return 3; } if(rateVal>110&&rateVal<=130){ return 4; } else { return -1; } } /* SerialEvent occurs whenever a new data comes in the hardware serial RX.
