Pūnaha rere hau aunoaka aroturukihia, ka pupuri hoki i te rere o te hau i roto i te whare rehu. Ina puru rawa ngā tātari, ā, kāore e taea te pupuri i te rere o te hau, ka mutu te mahi a te pūnaha hei tiaki i te haumaru.

✓

Pūnaha rehue whakamahi ana i ngā taraka hurihuri e rua (2) e taraiwahia ana e tētahi motuka servo DC hangarau matatau, kore paraihe, hei whakahaere i te haumaru me te whakahaere pai o te mahi hurihuri, kia rite ai te tere me te tauira rehu puta noa i te whānui o te kaikawe.

✓

Wāhanga whakahaere hikoe whakamahi ana i tētahi pae photodiode ono tekau (60) pūtau hei aroturuki me te whakahaere i te tono rehu, kia nui ake ai te whai huatanga o te whakawhiti tono.

✓

Pūnaha rehukua hangaia kia whakaaetia ngā pū rehu e waru (8).

✓

Mīhinie rua (2) ngā ara iahiko tuku paninga me te hangarua.
