Hello kind people, I am in the process of making a mood lamp using 20 RGB LEDs (common anode) and have 2 questions about the circuit: I plan to drive these LEDs with each color channel in parallel using an NPN transistor driven by a PWM pin (3 NPNs for 3 colors). 20 LED's would be ~400ma for each…

Thank you gentlemen.....think i will end up soldering separate resistors to each of the cathodes....60 resistors that’s going to be a task
