Mana Whakahaere Kaha o te Mōta Wiri Arduino
Ka taea e tātou te whakamahiPWM Arduinongā putanga hei whakahaere i te kaha wiri o te motuka wiri. Mā te whakamahi i tētahi huringa mahi taurangiTohu PWMmai i te Arduino i honoa ki teAtekōkiri putanga transistor BJT, ka taea e tātou te whakarite i te kaha wiri o te motuka.
Mēnā kei te whakamahi koe i te tohu PWM hei whakahaere i te kaha o te wiri, me hono te Fly-Back Diode ki te taha o te motuka wiri. Mā tēnei diode e tiaki te transistor taraiwa putanga mai i ngā pūwero irahiko e hangaia ana e te motuka.
Kauwhata Porowhita Mōta Wiri Arduino
He tūāpapa whakawhanake ngāwari te Arduino, he utu iti, ā, e tautokona ana e te hapori nui, kaha hoki. Nā tōna māmā noa iho te rongonui - kua whakauruhia te pūmana iti ki runga i te papa, ā, kua whakaurua kētia ngā wāhanga katoa e hiahiatia ana mō te hōtaka. Ko tāu noa he hono i te USB ki tō rorohiko, ka tango i te pūmanawa.
He maha ngā momo Arduino mō ngā tono rerekē. Ko te mea rongonui ko Arduino UNO R3. Heoi, kotahi te herenga matua hei mōhio māu ina whakamahi ana i te microcontroller hei taraiwa i te motuka: ko te nuinga o ngā motuka wiri DC e hiahia ana ki te ia tīmatanga me te ia whakahaere e nui ake ana i te kaha o te ia putanga o ngā pine microcontroller. Ko te tikanga me whai wāhanga takawaenga tātou i waenga i te microcontroller me te motuka. Ka whakamahia whānuitia e mātou te kupu "wāhanga" nā te mea he maha ngā kōwhiringa e wātea ana, tae atu ki ngā taraiwa motuhake, ngā maramara urupare haptic rānei. Kia māmā ai te mārama ki tēnei aratohu, ka arotahi mātou ki te whakamahinga o ngā transistors.
E whā ngā āhuatanga matua o te ara iahiko Arduino mō te motuka wiri:
●He pūmana iti
●He transistor
●He motuka wiri
●He pūtake hiko
Koinei te hoahoa waea mō te ara iahiko whakahaere o te mōtini wiri Arduino e whakamahi ana i te transistor hei pana puku. He mea nui kia mōhio ko te mōtini wiri e whakakahangia ana e te transistor e whiwhi ana i te mana DC 5V mai i te papa Arduino UNO. Tērā atu rānei, ka taea e tātou te whakamahi i te pine putanga 3.3V hei whakahaere i te mōtini wiri i roto i te huarahi iti ake engari haumaru ake.
Me pēhea te taraiwa i tētahi mōta wiri me Arduino
A motuka wiriHe taputapu iti te miihini e whakaputa ana i te wiri ā-ringa mā te whakamahi i tētahi motuka hiko he taumaha kore taurite kei runga i te rakau taraiwa. E whakamahia ana i roto i ngā momo tono hei whakarato urupare pā kia pai ake ai te atanga kaiwhakamahi ki te kaiwhakamahi whakamutunga.
E whakaatu ana te ahua i runga ake nei i te hanganga o roto o tētahi motuka wiri iti e kitea whānuitia ana i roto i ngā waea pūkoro, he rite ki ngā motuka wiri-iti e whakamahia ana i roto i ngā kaupapa Arduino. Kei raro nei he ahua o tētahi motuka wiri iti kua whakapirihia ki tētahi PCB, kua rite ki tētahi ara iahiko whakahaere transistor taraiwa hei hono ngāwari ki ngā momo pūmana iti.
Tata ki ngā tono katoa e pā ana ki ngā motuka wiri ka whakamahia ngā pūmana iti. Ahakoa ko ētahi tono ahumahi ka hiahia pea kia rere tonu te motuka wiri (i tēnei wā ka tūtohu mātou kia whakamahia hemōtini wiri kore paraihe), ko te nuinga me puta te wiri i ngā wā motuhake me te roanga kua tohua. I te hekenga o ngā utu me ngā rahi o ngā maramara, kua tino māmā te uru atu me te whakauru i ngā pūmana iti ki roto i ēnei pūnaha.
Me pēhea te whiriwhiri i tētahi mōta wiri iti Arduino?
He rerekē ngā momo mōtini wiri. Ka tūtohu mātou i tētahi mōtini wiri moni Arduino.Ngā motuka monihe kiato, ā, e whakamahia ana i roto i ngā taputapu iti.
Me whakarite kia hototahi te ngaohiko me te au o te motuka ki tō papa Arduino me te pūtake hiko.
Tirohia ngā whakatakotoranga kaha wiri o te motuka, i te nuinga o te wā i roto iTe kaha-G, m/s² rāneiKōwhiria he mōta e tutuki ana i ngā whakaritenga kaha wiri mō tō kaupapa.
Whakaarohia te rahi me te taumaha o te mōtini, ina koa mēnā he iti te wāhi o tō kaupapa, he iti rānei te māmā e hiahiatia ana.
Ki te whakaaro koe ki te whakarerekē i te kaha o te wiri mā te whakamahi i tētahiTohu PWM.
Tirohia me pēhea te whakamau i te mōtini ki roto i tō kaupapa. Kei ētahi mōtini he kōhao whakamau, he papa whakapiri rānei hei ngāwari ake te tāutanga.
Hei whakamutunga, whakaarohia tō tahua me ngā motuka e wātea ana mai i tō kaiwhakarato. Rapua he waitohu rongonui hei whakarite i te kounga me te pono.
Me pēhea te whakarite i te mōta wiri Arduino?
Kōwhiria he mōta wiri e tutuki ana i ngā whakaritenga o tō kaupapa e pā ana kite rahi, te ngaohiko, me te kaha o te wiri.
WhakamahiaPWM (Whakarerekētanga Whānui Pāorooro)hei whakahaere i te kaha o te wiri o te motuka. Mā tēnei ka taea e koe te whakarerekē i te huringa mahi hei whakarerekē i te kaha o te wiri.
Waihangahia he ara iahiko kei roto ko te Arduino, he transistor (he taraiwa mōtini rānei), me te diode flyback hei ārai i ngā pikinga ngaohiko. Honoa te mōtini ki te transistor, ka whakahaerehia e te tohu PWM mai i te Arduino.
Tuhia he papatono ki te Arduino IDE hei whakahaere i te motuka. Whakamahia te mahi `analogWrite()` hei tuku tohu PWM ki te transistor me te whakarite i te huringa mahi hei whakarerekē i te kaha o te wiri.
Mena e tika ana, ka taea te whakauru i ngā pūoko (pēnei i ngā ine whakatere) hei tuku urupare ki ngā taumata wiri, kia taea ai te whakarerekētanga hihiri i runga i ngā raraunga wā-tūturu.
Whakamātauria ngā tikanga whakairi, ngā whare rānei rerekē hei whakapai ake i te pai o te motuka, me te whakarite i te wheako wiri kia rite ki ō hiahia.
Whakamātauria tō tatūnga, ka whakarerekē i te waehere, te ara iahiko, te whirihoranga ā-tinana rānei ina hiahiatia hei whakatutuki i te mahi e hiahiatia ana.
