controlling transistors with the BSII

Obiwan

I am trying to build an h bridge circuit where the base is being pressed by the output pins of the BSII.· In one line of circuit, the positive power enters the collector of the PNP I am using and exits the emitter into a motor.· The other side of the motor goes to the collector of another PNP transistor whose emitter then goes to the negative battery.· I want both bases to be pressed by pins of the stamp.· For testing purposes, i set the whole thing up on a solderless breadboard and connected the bases through 4.7k resistors to pins.· Can I just do LOW 0 and LOW 1 on a loop to test it out?
