Temperature of the room

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 want to do serial communication
but i don't know how to connect RS232 with MAX232 with PIc18f4550??
can u help me to do the connection in proteus file that i attached it

you do realize that by posting proteus file you are limiting possible number of replies to those who have proteus installed?
why not include pdf file?

in my attached .rar file i included proteus file and hex file

no problem, i just looked at it and i hope this helps. it may solve both problems.
