thanks for the reply

eventually, this project used the ceiling fan motor-single phase motor...

can u suggest something...?

totally need help...

i am really blur and confused right know...can anyone tell me on how to interface the PIC16f877 with ac induction motor ( speed)...--ceiling fan...

guide me please....

urgent...

thanks for the info..really hope it function well for the project...

by the way, how about the interface with ac induction motor.. isn't been conclude in the book??

i hope for Ur opinion about that...

waiting for respond....

hi everyone,, 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- ...
