Error when comiling in Arduino IDE

[rstrich]

Have built and used your default pin layout, however get the following error when compiling using Arduino IDE, any suggestions?:-

C:[DocRoot]\Arduino\useless-box\proximity-sensor.cpp: In member function 'uint8_t ProximitySensor::getProximity()':
C:[DocRoot]\Arduino\useless-box\proximity-sensor.cpp:45:19: error: control reaches end of non-void function [-Werror=return-type]

I found the solution on that forum..
https://forum.arduino.cc/t/probleme-beim-kompilieren-in-der-arduino-ide/1094051/2

in proximity-sensor.cpp

Add a new line between lines 46 and 47. It should look something like this...

  }

return 0;
}

worked perfect for me
