Light multiple RGB Led Strips from same 3 RGB PWM outputs 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:

And what i want is something like this:

Is this possible? What should i modify to make it work?
Thanks in advance.
You have few options:


do as you represented in the drawing: it should work, as I expect the transistors to not load too much the input.
add a logic buffer inbetween the arduino and the driver stage
use other pins from the arduino for driving the additional strips and bitbang the PWM, instead of using the HW blocks


Whether the solution you propose (1) will work or not depends entirely on the max current that each PWM pin can output vs the total load from the 3 transistors it will have to drive.
