Multiple rgb control plus calculation help Hi me and a friend is making a computer shelf with leds in the woodwork, were using a special glue for the plexiglass in the shelf which means we're using individual rgb leds, four leds for each window (3 windows) and what I need help with is, amount of voltage, ampere, code and how to connect all this up. I've used 123d.io to sketch something up but I'm struggling with getting proper strength in the leds.

Aswell as some of them change colors as the picture here shows:


I'm very new at these things so I really appreciate all help and advice (and from an earlier post, reason for not using strips is purely based on the method of build, the shelf will not sit correct if the strips were in use)
It's not advised to connect leds in parallel, with only one common resistor. Slight difference in forward voltage of the leds will create big current differences. This will make some leds appear brighter that neighboring leds. It can also damage the brighter led since too much current can flow through them. So you need to add a resistor to each led, and common the other side of these resistors to the transistor. 

Second bigger error is that there isn't any resistor between the arduino pin and the base of the transistor. Without it there is nothing limiting the current going into the base, which could fry the arduino pin.
