I purchased a RFID reader and I pulled a servo out of an old RC plane. the goal is to use the servo to lock and unlock my dorm room door with just a tag. i was able to find a code but the writer make an error in the line that states:
"SoftwareSerial RFID = SoftwareSerial(rxPin,txPin);"
the error reads:
" In function 'void loop()':
error: 'SoftwareSerial' was not declared in this scope"
i have no clue how to declare it.
any help?
