Hi, I have a slight problem I have traced down to a transistor not turning off fully. It is a 2n3906. I control two 'common cathode RGB led' cathodes with a 2n3904 and 2n3906, the base resistors go to the same digital pin. Effectively when HIGH, the 3904 side is active, LOW the 3906. I have tried …

I had this problem as well. Increased amperage same voltage and it worked fine after.
