hello friends, would u help me about the programming for PIC microcontroller in case of 5 pin dc relay.
 

Use an NPN transistor to drive the relay. Send a logic 1 to the base of the transistor to turn on the transistor and hence drive the relay. Send a logic 0 to the base of the transistor to turn off the transistor. Use a current limiting resistor between the transistor base and the microcontroller pin. Make sure you configure that pin as an output by writing 0 to the corresponding TRIS bit. Do remember to connect a diode across the relay.

You have discussed this before here as well: https://www.edaboard.com/threads/253786/

What problems do you currently face?

Hope this helps.
Tahmid.
