Denne eksempelkoden viser hvordan du styrer opptil fire av våre lineære aktuatorer med Arduino Uno og LC-82 MultiMoto Arduino ShieldLignende produkter kan imidlertid brukes som erstatninger. Denne koden er kun ment for bruk med aktuatormodeller innenfor de gjeldende begrensningene på hver kanal i MultiMoto, for eksempel PA-14 og PA-14P.

/* Eksempelkode for å kontrollere opptil 4 aktuatorer ved hjelp av Robot Power MultiMoto-driveren. Maskinvare: - Robot Power MultiMoto - Arduino Uno Kabling: - Koble aktuatorene til M1-, M2-, M3- og M4-tilkoblingene på MultiMoto-kortet. - Koble den negative (svarte) til høyre tilkobling, den positive (røde) til venstre. - Koble en 12-volts kilde (minimum 1A per motor hvis ubelastet, 8A per motor hvis fullastet) til BAT-terminalene.
