Hi, I want to build huge 7segment display. I already made one using LED strips, but I was switching them using transistors, so I had to use on pin for each segment and I had problems with overheating ATmega when switching many transistors, so I wanted to build it using addressable LED strip. But I can't find single color one. I need maximum brightness, so I'd like to use SMD5050, all 3 LEDs on maximum, but all addressable strips are RGB, so this give me white color, but I'd like to have red one.
So, is there any way to have single color adressable led strip, or does exist something like addressable transistor? Or some kind of addressable switch, that I will be able to connect LED to every one and then switch every on/off using one or two pins like addressable LED strips. Thanks
