A ki uma Leds e fa'atali mo le tasi sekone ma tape le ta'ita'i i sekone ta'itasi, amata mai le led4 seia o'o i le led1.
O le relay1 o loʻo faʻatautaia mai le pine 4, le relay2 mai le pine7, le relay3 mai le 8 ma le relay4 mai le pine 12.
O le commutation e faʻatonuina e le "digitalWrite ()" galuega.
A fa'atūina fa'asolo e LOW, e fa'afeso'ota'i le feso'ota'iga "Masa masani" (C) i le feso'ota'iga "Normally Closed" (NC).
Nai lo o le taimi e setiina ai le maualuga, o le "Masa masani" (C) faʻafesoʻotaʻi e sui ma faʻafesoʻotaʻi i le "Normally Open" (NO) faʻafesoʻotaʻi.
O iinei e mafai ona e sii maia le Schematic of 4-Relays Shield.
O lo'o fa'aalia i lalo le fa'ailoga atoa ma lona fa'amatalaga auiliili.
