Tirohanga
Ko te arai haumaru taratahi me te mahi whakamarumaru o te whakaputanga whakawhiti urunga whakawhiti, e wehe ana, e tuku ana i nga tohu whakauru mai i nga hoapaki whakawhiti, i nga huringa tata ranei i nga waahi morearea ki te waahi haumaru me te transistor putanga ma te arai haumaru. Ka kitea te hapa o te raina ma te LED kei runga o te kōwae. Ka whakamahia te huringa waea o te kōwae ki te tautuhi i te whakaurunga me te whakaputa i roto i te wahanga-waahanga, whakamuri ranei i te mana whakahaere, me te whakaahei, te whakakore ranei i te mahi tohu whakaoho whakamohiotanga he.
Ko tenei hua e hiahia ana ki te tuku hiko motuhake, me te tuku hiko motuhake, te whakaurunga, me nga pito putanga.
