I roto i tēnei kaupapa, ka whakaaturia e mātou me pēhea te hanga i tētahimotuka wiriara iahiko
Hemōtini wiri dc 3.0vHe mōtini e wiri ana ina hoatu he mana nui. He mōtini e wiri ana. He tino pai mō te wiri i ngā mea. Ka taea te whakamahi i roto i ngā taputapu maha mō ngā kaupapa tino whaihua. Hei tauira, ko tētahi o ngā mea e wiri ana ko ngā waea pūkoro e wiri ana ina karangatia ana ina whakanohoia ki te aratau wiri. Ko te waea pūkoro he tauira o tētahi taputapu hiko kei roto he mōtini wiri. Ko tētahi atu tauira ko te kete rumble o tētahi kaiwhakahaere kēmu e wiri ana, e whai ana i ngā mahi o tētahi kēmu. Ko tētahi kaiwhakahaere ka taea te tāpiri i tētahi kete rumble hei taputapu ko te nintendo 64, i tae mai me ngā kete rumble kia wiri ai te kaiwhakahaere hei whai i ngā mahi petipeti. Ko tētahi atu tauira ko tētahi taonga takaro pērā i te furby e wiri ana ina mahi koe i ngā mahi pēnei i te mirimiri, te pēhi rānei, me ētahi atu.
Nō reiraaukume iti dc e wiri anaHe tino whai hua, he whai tikanga hoki ngā mahi a ngā ara iahiko motuka, ā, he maha ngā whakamahinga ka taea te whakamahi.
He tino māmā noa te whakakorikori i te motuka wiri. Ko tā tātou anake he tāpiri i te ngaohiko e hiahiatia ana ki ngā pito e rua. E rua ngā pito o te motuka wiri, he waea whero me te waea kikorangi te nuinga. Kāore he aha te polarity mō ngā motuka.
Mō tā mātou mōtini wiri, ka whakamahia e mātou he mōtini wiri nā Precision Microdrives. Ko te awhe ngaohiko whakahaere o tēnei mōtini he 2.5-3.8V hei whakakaha.
Nō reira, ki te hono tātou i te 3 volts puta noa i tōna pito, ka tino wiriwiri, pērā i te mea e whakaaturia ana i raro nei:
Koinei anake te mea e hiahiatia ana hei whakaoho i te motuka wiri. Ka taea te whakarato i te 3 volts mā te rua pākahiko AA e raupapa ana.
Heoi, e hiahia ana mātou ki te kawe i te ara iahiko motuka wiri ki tētahi taumata matatau ake, kia taea ai te whakahaere e tētahi pūmana iti pēnei i tearduino.
Ma tenei, ka taea e tatou te whakahaere hihiri ake i te motuka wiri, me te mea kia wiri i nga wa kua whakaritea mena e hiahia ana tatou, mena ranei ka puta he huihuinga motuhake.
Ka whakaaturia e mātou me pēhea te whakauru i tēnei mōta ki tētahi arduino hei whakaputa i tēnei momo mana whakahaere.
Ina koa, i roto i tēnei kaupapa, ka hangaia e mātou te ara iahiko, ka hōtakahia kia taea ai e temōtini wiri moniKa wiri te 12mm i ia meneti.
Ko te ara iahiko motuka wiri ka hangaia e mātou e whakaaturia ana i raro nei:
Ko te hoahoa kauwhata mō tēnei ara iahiko ko:
Ina taraiwahia he motuka me te microcontroller pēnei i te arduino kei a tātou i konei, he mea nui kia honoa he diode whakamuri whakarara ki te motuka. He pono anō hoki tēnei ina taraiwahia me te kaiwhakahaere motuka, te transistor rānei. Ka mahi te diode hei tiaki ngaru mai i ngā pikinga ngaohiko ka puta mai i te motuka. He rongonui ngā takai o te motuka ki te whakaputa i ngā pikinga ngaohiko i a ia e hurihuri ana. Ki te kore he diode, ka taea e ēnei ngaohiko te whakangaro ngāwari i tō microcontroller, i tō IC kaiwhakahaere motuka rānei, te whakakore rānei i te transistor. Ina tukuna noa te mana o te motuka wiri ki te ngaohiko DC, kāore he diode e hiahiatia ana, koia te take i roto i te ara iahiko ngāwari kei runga ake nei, ka whakamahia e tātou he pūtake ngaohiko anake.
Ka mimiti te pūnga hiko 0.1µF i ngā pikinga ngaohiko e puta mai ana i te wā e tuwhera ana, e kati ana hoki ngā paraihe, arā, ngā hononga e hono ana i te iahiko hiko ki ngā takai o te motuka.
Ko te take e whakamahia ai e mātou he transistor (he 2N2222) he ngoikore ngā putanga iahiko o te nuinga o ngā pūmana iti, arā, kāore e nui te iahiko e tukuna ana hei taraiwa i ngā momo taputapu hiko rerekē. Hei whakakapi i tēnei putanga iahiko ngoikore, ka whakamahia e mātou he transistor hei whakarato i te whakanui iahiko. Koinei te kaupapa o tēnei transistor 2N2222 e whakamahia ana e mātou i konei. Me 75mA te iahiko e hiahiatia ana mō te motuka wiri hei taraiwa. Ka taea tēnei e te transistor, ā, ka taea e mātou te taraiwa i teMōta momo moni 3v 1027Hei whakarite kia kore e nui rawa te iahiko e rere mai i te putanga o te transistor, ka whakatakotoria he 1KΩ kia raupapa ki te turanga o te transistor. Ka whakaitihia e tēnei te iahiko ki tētahi nui e tika ana kia kore ai e nui rawa te iahiko e whakakaha i teMōta wiri iti 8mmKia maumahara ko te tikanga ka tukuna e ngā transistors te whakanui ake i te iahiko turanga e uru ana mā roto i te 100 ngā wā. Ki te kore tātou e whakatakoto i tētahi ātete ki te turanga, ki te putanga rānei, ka kino pea te iahiko nui ki te motuka. Kāore te uara ātete 1KΩ i te tino tika. Ka taea te whakamahi i tētahi uara tae atu ki te 5KΩ pea.
Ka honoa e mātou te putanga ka peia e te transistor ki te kaikohi o te transistor. Koinei te motuka me ngā wāhanga katoa e hiahiatia ana e ia hei tiaki i ngā ara iahiko hiko.
