Denne eksempelkode viser, hvordan man styrer op til 4 af vores lineære aktuatorer med Arduino Uno og LC-82 MultiMoto Arduino ShieldLignende produkter kan dog bruges som erstatninger. Denne kode er kun beregnet til brug med aktuatormodeller inden for de nuværende begrænsninger på hver kanal i MultiMoto, såsom PA-14 og PA-14P.
