    Hi,

    I’m driving a suction pump through relay, im interfacing relay and PIC through ULN 2803. The problem is when i was using a 12 V pump it was running fine when i replaced it with 5V pump , PIC gets reset. relay clicks but PIC resets so prog stops there. the relay im using¬† is 12 V. can you tell me where the prob is?

    Use Separate Power Supplies for PIC and PUMP.
