{{ADFImage|Arduino-Memoire-50.jpg}} <span>Anything with an SD or Micro-SD interface requires a 512 byte SRAM buffer to communicate with the card.</span>

{{ADFImage|Arduino-Memoire-51a.jpg}}  <span>Each pixel requires just 3 bytes of SRAM to store the color. But those bytes start to add up when you have many meters of strip or a large array.<br />On an Uno, you might be able to drive as many as 500 pixels - assuming you don't use much SRAM for anything else.</span>

Chaque pixels nécessire 3 octets/bytes de SRAM pour stocker la couleur. Mais ce nombre d'octet s’additionne lorsque vous commencez à avoir plusieur mètres de pixels ou si vous composez un large tableau de pixels (un ''array'' de pixels comme disent nos amis anglophone).<br />Sur un Uno, vous devriez être capable de piloter jusqu'à 500 pixels - assuming you don't use much SRAM for anything else.</span>
