    Default LED with Transistor

    Hi guys... I am wondering how do we light up so many LEDs in one I/O pin. I have around 50 LEDs that need to be turned up which are controlled by PIC16F84A. So, I am thinking of putting a BC547C transistor as the switch. However, I am not sure about the connection and also the code. Does anybody can give me any suggestion?

    I've attached my schematic. Thank you
