Ma mua o ke kau ʻana i nā uwea, pono mua mākou e maopopo e pili ana i nā hana o nā pine ʻelima o ke pihi kaomi.
Ke lawe nei iā ONPOWKuapo pihi kaomi 5 pinema ke ʻano he laʻana.
ʻOiai paha he ʻokoʻa ke ʻano o nā pihi hoʻololi a me ka hoʻokaʻawale ʻana o nā pine, ua like loa kā lākou mau mahele hana.
-ʻO ka ʻāpana muaʻo ia nā pine LED (hōʻailona ʻulaʻula). ʻO ka hana ka hāʻawi ʻana i ka mana i ke kukui LED. ʻElua mau ʻano maʻamau, i māhele ʻia i nā pou maikaʻi a me nā pou maikaʻi ʻole. ʻO ka maʻamau, e hōʻailona ʻia ʻo "+" a i ʻole "-" ma kahi kokoke i nā pine.
-ʻO ka ʻāpana ʻeluaʻo ia nā pine kuapo (hōʻailona ʻia me ka uliuli). ʻO ka hana ka hoʻohui ʻana i ka hāmeʻa āu e pono ai e kaohi. ʻEkolu mau mea maʻamau, me nā hana o "pine maʻamau", "hoʻokaʻaʻike wehe maʻamau" a me "hoʻokaʻaʻike pani maʻamau". ʻO ka maʻamau, e hōʻailona ʻia ʻo "C", "NO" a me "NC" kokoke i nā pine. ʻElua wale nō pine a mākou e hoʻohana ai. Ke hoʻohana mākou iā "C" a me "NO", e hoʻokumu ʻia kahi kaapuni wehe maʻamau no ke pihi kaomi. Ma lalo o nā kūlana maʻamau, ke kaomi ʻoe i ke pihi, e huli ka hāmeʻa āu i hoʻopili ai. Ke hoʻohana mākou iā "C" a me "NC", e hoʻokumu ʻia kahi kaapuni pani maʻamau. （He aha ka manaʻo o ka "normally open" a i ʻole "normally close"?）
He maʻalahi ka nīnau ma lalo nei. Pono mākou e ʻike pehea e hoʻopili ai i nā uaea kūpono i nā pine kūpono.
Eia nā kuhikuhi uea maʻamau.
(Ma mua o ke kau ʻana i nā uwea, e ʻoluʻolu e hōʻoia i kūlike kāu lako mana me ka hōʻailona LED ma ke pihi.)
ʻIke hou aku
——E kūʻai i ke kuapo pihi 5 pin maikaʻi
——Pehea e hoʻopili ai i kahi kuapo pihi 3 pin
——Pehea eueahe kuapo pihi 4 pin
