Before using mySerial in the 'offending' line, you need to declare a SoftwareSerial object; read up on SoftwareSerial in the library section.

Code: [Select]

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.
