  • Arduino应用_Arduino连接超声波传感器测距

    超声波传感器适用于对大幅的平面进行静止测距。普通的超声波传感器测距范围大概是 2cm~450cm,分辨率3mm(淘宝卖家说的,笔者测试环境没那么好,个人实测比较稳定的 距离10cm~2m 左右,超过此距离就经常有偶然不准确的情况发生了,当然不排除笔者技术 问题。) 测试对象是淘宝上面最便宜的SRF-04 超声波传感器,有四个脚:5v 电源脚(Vcc),触发控制端(Trig),接收端(Echo),地端(GND) 附:SRF 系列超声波传感器参数比较   模块工作原理: 采用IO 触发测距,给至少10us 的高电平信号; 模块自动发送8个40KHz 的方波,自动检测是否有信号返回; 有信号返回,通过IO 输出一高电平,高电平持续的时间就是超声波从发射到返回的时间.测试距离=(高电平时间*声速(340m/s))/2; 电路连接方法   Arduino 程序例子: constintTrigPin = 2; constintEchoPin = 3; floatcm; voidsetup() { Serial.begin(9600); pinMode(TrigPin, OUTPUT); pinMode(EchoPin, INPUT); } voidloop() { digitalWrite(TrigPin, LOW); //低高低电平发一个短时间脉冲去TrigPin delayMicroseconds(2); digitalWrite(TrigPin, HIGH); delayMicroseconds(10); digitalWrite(TrigPin, LOW); cm = pulseIn(EchoPin, HIGH) / 58.0; //将回波时间换算成cm cm = (int(cm * 100.0)) / 100.0; //保留两位小数 Serial.print(cm); Serial.print("cm"); Serial.println(); delay(1000); }

  • Arduino学习笔记3_连接HMC5883L三轴电子罗盘传感器

    用途:测量地磁方向,测量物体静止时候的方向,测量传感器周围磁力线的方向。注意,测量地磁时候容易受到周围磁场影响,主芯片HMC5883 三轴磁阻传感器特点(抄自网上): 1,数字量输出:I2C 数字量输出接口,设计使用非常方便。 2,尺寸小: 3x3x0.9mm LCC 封装,适合大规模量产使用。 3,精度高:1-2 度,内置12 位A/D,OFFSET, SET/RESET 电路,不会出现磁饱和现象,不会有累加误差。 4,支持自动校准程序,简化使用步骤,终端产品使用非常方便。 5,内置自测试电路,方便量产测试,无需增加额外昂贵的测试设备。 6,功耗低:供电电压1.8V, 功耗睡眠模式-2.5uA 测量模式-0.6mA   连接方法: 只要连接VCC,GND,SDA,SDL 四条线。 Arduino GND -> HMC5883L GND Arduino 3.3V -> HMC5883L VCC Arduino A4 (SDA) -> HMC5883L SDA Arduino A5 (SCL) -> HMC5883L SCL (注意,接线是A4,A5,不是D4,D5) 源程序: #include <Wire.h> #include <HMC5883L.h> HMC5883Lcompass; voidsetup() { Serial.begin(9600); Wire.begin(); compass = HMC5883L(); compass.SetScale(1.3); compass.SetMeasurementMode(Measurement_Continuous); } voidloop() { MagnetometerRaw raw = compass.ReadRawAxis(); MagnetometerScaled scaled = compass.ReadScaledAxis(); float xHeading = atan2(scaled.YAxis, scaled.XAxis); float yHeading = atan2(scaled.ZAxis, scaled.XAxis); float zHeading = atan2(scaled.ZAxis, scaled.YAxis); if(xHeading < 0) xHeading += 2*PI; if(xHeading > 2*PI) xHeading -= 2*PI; if(yHeading < 0) yHeading += 2*PI; if(yHeading > 2*PI) yHeading -= 2*PI; if(zHeading < 0) zHeading += 2*PI; if(zHeading > 2*PI) zHeading -= 2*PI; float xDegrees = xHeading * 180/M_PI; float yDegrees = yHeading * 180/M_PI; float zDegrees = zHeading * 180/M_PI; Serial.print(xDegrees); Serial.print(","); Serial.print(yDegrees); Serial.print(","); Serial.print(zDegrees); Serial.println(";"); delay(100); }

  • This algorithm was developed by Professor Ronald L. Rivest of MIT and can be found presented in seve

    This algorithm was developed by Professor Ronald L. Rivest of MIT and can be found presented in several languages. What I provide to you here is a C++ derivative of the original C implementation of Professor Rivets. The library code itself is platform-independant and has been tested in Redhat Linux. I ve included the sample code and makefile that I used for the Linux test. The demo, however, was written with Visual C++ 6 on a Windows 2000 platform.
