Muntatge electr\u00f2nic"},"content":{"rendered":"\n

Primer es va fer una prova amb un sol sensor d’ultrasons. Evidentment, l’\u00fanic que s’aconseguia era saber la dist\u00e0ncia de l’objecte detectat al sensor.<\/p>\n\n\n\n

A continuaci\u00f3 es va provar amb un muntatge electr\u00f2nic basat en 2 sesnsors d’ultrasons. \u00c9s el que s’indica a continuaci\u00f3.<\/p>\n\n\n\n

Notes importants<\/strong><\/h3>\n\n\n\n
    \n
  • El servo pot consumir pics de corrent i aix\u00f2 podria provocar que l\u2019Arduino es reinici\u00e9s. Per evitar-ho, \u00e9s recomanable alimentar el servo amb una font externa de 5V compartint GND.<\/li>\n\n\n\n
  • El GND de l\u2019Arduino i el GND de la font externa han d\u2019estar connectats.<\/li>\n<\/ul>\n\n\n\n

    Limitacions<\/strong><\/h3>\n\n\n\n
      \n
    • La triangulaci\u00f3 amb 2 sensors d’ultrasons no es pot portar a terme. Es necessiten, com a m\u00ednim, 3 sensors d’ultrasons.<\/li>\n<\/ul>\n\n\n\n
