[Moved] Request : 3 segment Timer with remote control facility.........

Hi everyone....
I need a circuit diagram for a timer based 89c2051....
I attached photo of a prototype that i want....
I dont have a circuit Diagram.
so I want a circuit diagram and relevent programe for the microcontroller.

My needs is as follows....

1. 3 seven segment display, each display can set 0 to 9
2. when press the next Up/Dn button, save the previous display setting , ie, the first digit setting.
3. we can set the time 5 minutes to 0.01 seconds...
4. After setting the display, the display will shown the ON time of the timer.
5. After press the 'set' button, the timer will run and reached the 0.00 the will go to the display setting position, ie
we set the time 4.30 and press button 'set' the timer will go 4.29>4.28>>>>>>>>0.58>0.59>0.00, the the display go to 4.30.

Your thread was posted to the wrong (DIY) section.
I have no idea about 89c2051 but what I can tell you is that your last comment "I pay if any one could help me" will put away people because it shows that you are not here to learn but just to get the project done and this will not be appropriated much.
