I would like to drive 5x 12V RGB ledstrips (only 5x3 leds) on 2x 74HC595 shiftregisters (using the ShiftPWM library). The ledstrips have an common anode. They should stay individual addressable.
Do I have to use transitors for each R,G,B line of all the 5 ledstrips? That would be 15 transistors on the pcb!? :( Is there a better solution?
Regards and thanks in advance!
