Thanks to all the reply,

After I change it to PIC16F876 and 4Mhz cystal, pause 500, commandus 2000 and dataus 1000. It is work.
I had adding 4 button to increment the hrs,minute,day and month.
I feel happy.THANK YOU ALL THAT PROVIDE ME A LOT OF INFORMATION.

I have thinking to advancing my project by using the A/D function.
The idea is get the input from the solar PV and sent into the PIC16F876.
When the voltage is lower than 2 volt then motor stop and vice versa.
The input voltage from the solar PV is up to 15 volt.

Can someone help and guide me thru the basic part such as the initialization of the of the PIC???
Possible that the PIC get the analog input above 5Volt????

Any suggestion and Please advice....Thanks
