AA batteries are surprisingly potent little things, and a set of four can comfortably run about a meter of LPD8806 LED strip or one strand of 25 12mm pixels for a couple hours or more. You can go beyond this to create larger projects, with some forethought…

Les piles AA sont des petites choses vraiment surprenantes et un ensemble de 4 piles peut permettre de faire fonctionner confortablement un ruban d'un mètre de LPD8806 ou un ruban de 25 pixels de 12mm pendant deux heures ou plus. Vous pouvez néanmoins allez au delà de ces limites en créant des projet plus importants en faisant preuve de prévoyance.

* A fully-lit 1 meter strip can demand close to 2 Amps, but the batteries and diode are only rated for a continuous output of about 1 Amp. You can push beyond this for brief intervals, but it {{underline|can’t be sustained}}. Design your software so that the LEDs seldom or never exceed this level, using the 60 mA rule of thumb.
