I need to control about 6 RGB Led Strips from an Arduino Board. The problem is that i need 3 PWM outputs for each led strip, but each will have probably the same colors. I was wondering if i could put two strips receiving a signal from the same PWM output, then i would have to use half the PWM outputs but send the same signal for each pair of strips.

The scheme i found is this one:

[![arduino schematic][1]][1]arduino schematic

And what i want is something like this: [![enter image description here][2]][2]enter image description here

Is this possible? What should i modify to make it work?

Thanks in advance. [1]: https://learn.adafruit.com/system/assets/assets/000/002/693/medium800/led_strips_ledstripbjt.gif?1396785837 [2]: https://i.sstatic.net/yokZr.png
