employee attendance system using arduino wifi

hi everyone..

Iam busy designing a Fingerprint based employee attendance system using a fingerprint sensor (rg-511c3 module), Arduino Wifi, Raspberry pi for database, esp8266 wifi and a servo motor.

iam experiencing some programming difficulties in connecting the arduino wifi to a raspberry pi to save the templates and how to program the arduino wifi so that it can allow for authetification through to an esp8266 module which must turn the motor 180 degrees to open the door if the match is granted.

I also want to display the employee name and to say that ' access granted' or access denied' on the LCD display..
I attached the block diagram for clarity.

can anyone help me with writing the codes of this project if possible?.. or sources where I can get help in this project...please help me guys.. thank you in advance...

That means that you have some code. Don't expect us to guess what you have.

Which WiFi device/shield is connected to the Arduino? What is the other one connected to?

On a post-it note that you stuck to your monitor?

What is the point of using an Arduino when you have an ESP8266?

As for help with writing code . . . . either you want to pay someone to actually write the code, or you actually do some work and get help when you run into problems. That's how things work around here.
