I am using a 5volt WS2812b LED strip with a 5volt mini controller. When I connect the LED strip and controller to my power supply it works flawlessly. When I connect to a 9v battery instead my LED strip lights up one solid color and the controllers buttons appear to do nothing.
I thought for some reason the voltage being so high above the strips rated value had something to do with it so I took a 7805 voltage regulator, a 10uf electrolytic cap on the + in, a 10uf electrolytic cap on the + out, and a .1uf ceramic cap on the + out to create a small voltage regulator circuit.
I tested the circuit with my DMM and with my 9v input I get a steady 4.98v output, but again the LED strip lights up one solid color. I am at a loss for why this LED strip and controller work flawlessly on my power supply feeding it 5.02v but I get this one solid color with my 4.98v battery voltage regulator setup.
Any help and insight is greatly appreciated.
