Този примерен код показва как да контролираме до 4 от нашите линейни задвижвания с Arduino Uno и LC-82 MultiMoto Arduino щитВъпреки това, подобни продукти могат да се използват като заместители. Този код е предназначен за употреба само с модели задвижващи механизми в рамките на текущите ограничения за всеки канал на MultiMoto, като например PA-14 и PA-14P.

/* Примерен код за управление на до 4 задвижващи механизма, използвайки драйвера Robot Power MultiMoto.
