Tirohanga Whānui
Ko te ārai haumaru motuhake me te putanga transistor tāuru pana, e wehe ana, e tuku ana hoki i ngā tohu tāuru mai i ngā hoapā pana, i ngā pana tata rānei i ngā wāhi morearea ki te rohe haumaru me te transistor putanga mā te ārai haumaru. Ka tutuki te kimi hapa raina mā te rama LED kei runga o te kōwae. Ka whakamahia te pana waea o te kōwae hei whakatakoto i te mana whakauru me te putanga ki te wā-wāhanga, ki te whakamuri rānei, me te whakahohe, te whakakore rānei i te mahi tohu whakaoho kimi hapa raina.
