Hello,
Created a working board a few months back. Returned to it. The board was working but the code had been lost.
Trying to use the given code by the manufacturer of the laser finder (below), I get errors I can't understand.
Any help or suggestions greatly appreciated.
the errors I get are :

Here is the code as given on the website ..I've only changed the library include method because it doesn't find it otherwise.

//#include <SoftwareSerial.h> it doesn't find the library with this one

distance=(data[3]-0x30)*100+(data[4]-0x30)*10+(data[5]-0x30)*1+(data[7]-0x30)*0.1+(data[8]-0x30)*0.01+(data[9]-0x30)*0.001;

Serial.print(distance,3);
Serial.println(" M");
}
}
else
{
Serial.println("Invalid Data!");
}
}
delay(20);
}
}
and here is the library as i found it online on github. I don't even know if it is the right one, but it seems like it is and I can' t find it anywhere else.
