My project has my Arduino controlling 10 led strips. I'm going with a plan by @gre_gor that is posted here: Setting 10 RGB Strips Independently from Single Arduino ...where each strip is controlled by an STM32 driver.
I'm packing all electronics into a tight space and will need to have the power adapter external with just the cable coming in.
I need power both to the arduino and directly to the stm32's.
Question: can I simply split the 12V power cable to send power to both the led strips and the arduino? Or is there something I should worry about?
