Hi, I am trying to determine what would be a feasible approach to controlling a matrix of 32x32 LEDs where each LED can have variable voltage input e.g. 0 to 6V. Would something like this be possible using an Arduino? Thanks.

Controlling a matrix of LEDs

People normally use PWM to control Led intensity, rather than voltage level.
