I can not connect sensors with Arduino Uno fingerprint FPM10 R3. I have downloaded the library from address GitHub - adafruit/Adafruit-Fingerprint-Sensor-Library: Arduino library for interfacing to the fingerprint sensor in the Adafruit shop
and follow the instructions but now announced as follows 
Please help me
Make sure you have installed the library in the correct place.
Before using mySerial in the 'offending' line, you need to declare a SoftwareSerial object; read up on SoftwareSerial in the library section.
SoftwareSerial mySerial(somepin, anotherpin);
AdaFruit_Fingerprint finger ....
Please don't use stupid screendumps to post code. Copy and paste code and error message between code tags [code] and [/code]. Also reduce the size of picture how everything is connected; not everybody has unlimited bandwidth.
