This class allows you to get datas from the HC-SR04 sensor easily in C++!

• Download WiringPi library

    git clone git://git.drogon.net/wiringPi
    cd wiringPi
    git pull origin
    cd wiringPi
    ./build
  

• Use the Sonar class as follows:

    Sonar sonar;
    int distance = sonar.distance(30000); // 30000 is a timeout in microseconds
