help me out in my 8051 temperature controlled fan

im facing problem writing the program for this particular project and im blur in programming.
it is in assembly language.

Looks like i have seen this circuit before too...
I think you are from Malaysia too.. one of your friend is working on the same thing.. and he also has a thread going on.. you can join and start your programing. I have explained few things which are necessary for your project. So please go through the thread.

thnks for replying but u see, before i post , i have went through the link u gave me but i i am still blur on which part of this project comes 1st. moreover i also would like to add optional items, like different led colour indicating different temperature and when it comes to the max temperature a buzzer was alert.

well if you ask me.. you must learn to write basic working of the project instead of going into the advance features of your projects.
First try to make you peripherals of your board work then think of something else. I mean make your FAN run, write small driver function that can write numbers on 7-seg display. If you are ready with your basic firmware only then you can write the advance controls and features. Hope you getting my point.

alright. with the help of my members i guess i have did wat u told me too... wat is next then??

let me see what you did
