Your project idea is very large in scope and needs to be broken down into sub projects, then research them independently. BTW, where did you get this idea from?
- Interfacing the LCD with the PIC. What LCD? Why a PIC16?
- Interfacing the PIC with the PC. Serial? Parrallel? USB? Ethernet? WiFi?
- Encoding and transferring the data from the database to the PIC.
That should get you going on research projects. This is not going to be easy or quick to do, so expect to do a lot of research.
