I should mention I have 4 strips of 45 leds each, and I have tested with a power supply at 5v, it drains about 1.5A,
I have also tested powering them with 3 AAA batteries, and they work with some dimmer,
Should I add a capacitor between the power supply and the led strip?
which size you recommend me?
And a resistor to the data in? which size?
Should I connect the end of the strip to the ground and voltage too? or it doesn't matter.
which should allow me to drain 15A a step down regulator
