Edit, when I have interface the PIC with my relay with LED as output, the circuit works perfectly with the program of my PIC.
But, when I change the output of the relay to motor, when I press the button, the motor would not turn on (the relay did not switch on also), but when I turn on the relay manually by connecting the input of relay to VCC, the motor works perfectly. It seems the input of my relay cannot detect anything from output of PIC when I switch the output of relay to motor, while when with LED it works perfectly.
Any solution to this?
