Temperature of the room

[Afnan_123_]

Hi everyone,
please i am doing project about measure the temperature of the room, if the temperature is more than 24 the led will turn on
i should connect crystal with capacitors for OSC1 and OSC2 pins 13 and 14 of PIC
can anyone tell what is the suitable value of crystal and capacitors??

also , can you give me ideas to develop this project??

this is my attached file
it include proteus file and the code

What is the problem? I see it is working. Use 4 MHz crystal and 27 pf capacitors.

yes it's working, but just i asked about the value of crystal and capacitors

but i want help, how can i do serial communication for this porject?

You are using mikroC and it is very easy to do Serial communication with UART library. See UART example in the example folder. Are you going to connect MCU to PC using MAX232?

yes, but can u please do the connection in proteus??

See mikroC PRO manual. There is an example of RS232 interface with PC. In that the Circuit is given. If that doesn't help, I will try to draw the circuit.
