I have an array of LED clusters for a big VU meter. How can I distribute power evenly? Answered
Each cluster consists of 6 LED's, and is controlled individualy by an arduino (through a transistor).
If I start with normal power, when more LED's light up, they all dim. If I start with extra power, the first few LED clusters blow.
I don't want to have a separate power source for each cluster (there are 15)
