LED growth, shift register, Capsense....HELP!!!

Hi,

I am developing an electronic product as part of my Industrial Design course, and I have got a certain way but not quite there.

I have developed code for the growth of 6 LEDs (1, 1+2, 1+2+3 etc) but I need this pattern to extend across 14, still using the same 6 PWM outputs on the Arduino board. Was just wondering whether anyone had any experience, or whether they had any code, shift register etc?

The input to start the growth is a simple on/off capsense which is all working.

Probably a very simply problem, but I am a complete novice.

Any help would be much appreciated,

Laurie.
