Help me make a light measuring circuit using PIC

concerning to my measurement project I want to make light measuring circuit using PIC .... please help!!
Thanks in advcance!

measurement project

1. Use a PIC with and ADC on chip. (many choices)

2. Use an LDR and a fixed resistor to generate a voltage varying with light.

3. Use a lookup table to calibrate with light units (like lux or candelas)

Thanks a lot but could you tell me how to get start with that?!
you might guide me with website or somethinglike this... Please I need more help about my project!

measurement project

You will have to tell me about the project in detail. But please dont expect anyone to do the project for you unless you pay them. I can give you a guideline for free. There are many websites that have lots of training matterial. Microchip (PIC manufacturer) has all the tools to get you started for free.

Of course I don't want anyone to do the project me..so why is it my project!
Concerningto websites I want to know about those who have the circuit diagrams or schematic (for exmple light measuring circuit)..
What can i find at microchip website ?! It's a huge site that provides everything about PIC such as datasheets, I don't think i could make that benefit of it!
If the measuring project using PIC is very difficuit, i'll make it without using PIC...really don't know how to get a start with measuring project, please I need more support!
Thanks in advance!

Added after 55 minutes:

Anyway I found this website, open this link and give me your opinion:

measurement project

have you used the PIC for any project before?

no, but i'm trying to learn...I was wondering if there's any asm file prepared previously for these purposes....anyway i don't know, please keep in touch with me

No, I dont think you will get a readymade solution for this. You will have to follow a proper path. Here is what I suggest.

Option #1
------------
If you want to avoid learning to use and program the PIC, you can use the circuit given in the website mentioned by yourself. This is the analog approach to the project and is fairly straight forward. Provided that you know how to use the simple op-amps and other electronic components.

Option #2
------------
If you want to use the PIC, you will have to do some study. The good news is that the analog circuit becomes very simple since you are doing the computations in software. But you need to have some sort of display to read the results.
So I suggest that you start learning to use the PIC. There are hundreds of websites and learning matterial.
