ʻO ka ʻokoʻa ma waena o apihi kaomi ʻelua-pina he apihi paʻi ʻehāaia i ka helu o nā pine a me kā lākou mau hana.
I ka hapanui o nā hihia, hoʻohana ʻia kahi pihi ʻehā-pin no nā pihi hoʻomālamalama i hoʻomālamalama ʻia a i ʻole nā pihi paʻi multi-contact.Hoʻohana mau ʻia nā pine ʻē aʻe i ke pihi ʻehā no ka hoʻoulu ʻana i ke kukui LED a i ʻole ka hoʻomalu ʻana i kahi hui hou o nā mea hoʻopili.No ka hoʻokaʻawale ʻana i nā pine no ka mana o ka LED a i ʻole ka hoʻomalu ʻana i nā pilina hou aʻe, hiki iā ʻoe ke nānā i ke ʻano o ke pihi e ʻike inā he kukui a nānā paha i nā kaha ma ka ʻaoʻao o nā pine (nā pine i kapa ʻia me "-" a me "+" no ka mana LED, aʻo nā mea ʻē aʻe no nā pilina hou aku).
Aia kekahi mau ʻano pihi pana me nā hana like ʻole.ʻo kahi laʻana:
a. ʻEkolu-pin pihi pihi: Hoʻokahi pine maʻamau o kēia ʻano pihi, hoʻokahi pine paʻa mau, a hoʻokahi pine hāmama maʻamau.Ke hoʻohui ʻoe i nā uwea i ka pine maʻamau a me ka pine hāmama maʻamau, e pani mau ʻia ke pihi a hoʻopili ʻia ke kaomi ʻana.Ke hoʻohui ʻoe i nā uwea i ka pine maʻamau a me ka pine paʻa maʻamau, e wehe maʻamau ke pihi a wāwahi i ka pilina ke kaomi ʻia.
b. Pihi pihi ono-pin: ʻO kēia ka mea nui he pihi ʻekolu-pin hana pālua.Hāʻawi nā pine ʻē aʻe i nā koho mana hou a i ʻole nā pili pili. ʻO kahi ʻano ʻē aʻehe pihi ʻelua pine i loaʻa ka mālamalama mālamalama a me nā mea hoʻopili mana hou.
c. Pākuʻi lima-pin: ʻO ka maʻamau, ʻo ka pihi ʻelima-pin he pihi ʻekolu-pin me LED.
ʻOiaʻiʻo, nui nā ʻano like ʻole a me nā ʻano pihi i loaʻa.Inā makemake ʻoe e aʻo hou aku, e ʻoluʻolu e ʻoluʻolukāhea iā mā˚ouma ke kaomi 'ana maanei.Mahalo no ka nānā 'ana mai!
