I need to step down 12V to 3.2V to power 512 LED's in a parallel circuit, 256 in each. How can I do this?
My power source has 12V, 6A. Each LED draws 10-20ma and is powered on 3.2 V. Ive tried looking up how to do this already but havent really found anything like what im trying to do. The LED's will not all be on at the same time, im building an LED cube that pulses to music.
