Fingerprint Door Lock Using Arduino Circuit Diagram

Circuit diagram of the fingerprint door unlock system the brain of the circuit is arduino uno mcu board board1. In that i am using 2 3 digital pins of arduino for data transfer to the fingerprint i tried other pin configurations for this but it didn t work but as i am connecting lcd it also requires same 2 3 digital pins of arduino and it is not possible for me to use 2 and 3 pins of arduino for both lcd and fingerprint sensor for data transfer. We used analog pins since we need more that 14 digitals pins for this project.
