Sorry, the diagram is on another page - I meant NPN, as well as the PNP.
I thought the collector resistor is to limit the Ic max? As long as the Ic is below Ic max, Ic is controlled by the base current isn't it?
Only if you're using the transistor as an amplifier and not a switch - add NPN's and lower the resistors - all removing the resistors would do is strain the PIC.
