Thanks for the help Mike it means alot. The areas are small and of triangle shape with a footprint of roughly 100cm2. They will be relatively bright as they need to illuminate semi-opaque acrylic. They should only require 3 LED's at max (Red, Green, Blue) or just one combined RGB LED.
To make this circuit work is there anything i need apart from - LED's, Resistors, Driver, Power source, Arduino and a breadboard to mount them on?
