hi everyone,, ceiling fan project

i want to ask for a guidance for my project . The project basically use Temperature sensor (LM35) as input , PIC as "analyze" item and ac motor (output-speed change)..

here the problem is regarding 2 things

1. ADC problem-- LM35 interface pic
-either use PWM or sampling

2.the big one- how to interface PIC 16f877 and ac motor--can someone provide some diagramm..just for the guidance..

to be truth... i quite new in this area (microcontroller)....someone please...

wait for ur respond... i'm newbiee here...
 

thanks for the info...however, i have left micro controller knowledge since 2 years...i just need to refresh back...so, i am truly sorry because i can't understand clearly with the info given...

i hope u can give some explanation...basic thing i thought is OK...i am truly sorry for my weakness....
