I got a USB led strip from Ebay. Unfortunately there is no indication what type of led it is. Looking at power converter it says "5V Output 3x2A"
One strip has 15 leds. I want to connect it via standard battery (9V but if 3xAA are better they I am open to that.)
Also I wanted to add 3 potentiometers to be able to control each color separately. I did this on my Arduino - connected 3 10k Potentiometers and it kinda works but the knobs are not linear so I get full power when "open" and if I just "close" is a bit it loses like 50% power.
Not sure what's the best circuit I should build to make this work.
Any advice would be helpful.
Pictures attached for reference.
