I-Arduino Nano: konke odinga ukukwazi mayelana naleli bhodi lokuthuthukiswa

U-Arduino Nano Ngenye yezinguqulo lapho ungathola khona ibhodi elidumile lokuthuthukisa i-Arduino. Incane, kepha ungakhohliswa ngosayizi wayo, ifihla amathuba amaningi. Kufana nommese wangempela wamasosha waseSwitzerland wezinto zikagesi. Ngayo ungakha inqwaba yamaphrojekthi lapho kubalulekile khona ukugcina ukusetshenziswa nosayizi kutholakala.

Njengawo wonke ama-Arduino namabhodi ahambisanayo, inokufana nabanye odadewabo abadala, yize inezici ezithile zobuchwepheshe ezihlukile futhi ezihlukile kwabanye. Kulesi sihloko uzobona bonke labo ukufana nokwehluka ukuze ukwazi ukuqonda konke odinga ukukwazi mayelana naleli bhodi bese uqala ukwenza amaphrojekthi wakho we-DIY no-Arduino Nano.

Yini i-Arduino Nano?

I-Arduino Isivele ingeyakudala emhlabeni we hardware libre nomhlaba umenzi. Ngokuthuthuka kwayo kanye namabhishi esoftware ungakha inqwaba yamaphrojekthi lapho umkhawulo uwumcabango wakho futhi kahle ... ukulinganiselwa okuthile kwezobuchwepheshe. Kodwa zikuvumela ukuthi ufunde i-electronics, ukuhlela futhi udale izimangaliso zangempela.

Ngisho namaphrojekthi obuchwepheshe asuselwa kulawa mabhodi entuthuko. Uma kwenzeka kuba I-Arduino Nano, inguqulo encishisiwe de Arduino UNO. Lokhu kunciphisa ukufunwa kwamandla owasebenzisayo futhi kusho nokuthi kunesikhala esincane esidingekayo ukufaka ibhali, okwenza kube kuhle kumaphrojekthi lapho usayizi ubalulekile khona.

Akuyona ipuleti lena Arduino UNO yenziwe miniaturized ncamashi, njengoba uzobona kukhona eminye umehluko obalulekile wezobuchwepheshe. Futhi akuyona enye indlela I-LilyPad. Kepha yabelana ngezinye izici nengqikithi ekhona kuwo wonke amaphrojekthi we-Arduino. Vele, ingahlelwa okufanayo I-Arduino IDE njengabanye.

Izici zobuchwepheshe

Ibhodi le-Arduino Nano linezici ezithile zobuchwepheshe okufanele wazi ngaphambi kokuqala ngalo, ngaphezu kwalokho hlola ukuthi ngabe kuyilokho okudingayo yini ngephrojekthi yakho noma ayihlangabezani nokulindelwe.

Isisekelo izici zobuchwepheshe Yilezi:

Ibhodi le-microcontroller elincane, eliguquguqukayo futhi elisebenziseka kalula.
Kususelwa ku-Atmel ATmega328p microcontroller noma i-MCU kuzinguqulo 3.x naku-ATmega168 kuzinguqulo ezedlule. Kunoma ikuphi, kusebenza kumvamisa we-16 Mhz.
Imemori iqukethe i-16 KB noma i-32 KB flash kuye ngohlobo (2KB esetshenziselwa i-bootloader), ene-1 noma 2 KB yememori ye-SRAM kanye ne-512 byte noma i-1 KB EEPROM ngokuya nge-MCU.
Ine-voltage yokuphakela engu-5v, kepha amandla wokufaka angahluka kusuka ku-7 kuye ku-12v.
Inezikhonkwane eziyi-14 zedijithali, izikhonkwane eziyi-8 ze-analog, izikhonkwane ezi-2 zokusetha kabusha nezikhonkwane zamandla eziyi-6 (i-Vcc ne-GND). Kuzikhonkwane ze-analog nezedijithali, zinikezwa imisebenzi eminingi eyengeziwe efana ne-pinMode () ne-digitalWrite () ne-analogRead () yama-analogs. Endabeni yama-analogs, avumela ukulungiswa kwe-10-bit kusuka ku-0 kuye ku-5v. Kumadijithi, ama-22 angasetshenziswa njengokukhipha I-PWM.
Akubandakanyi isokhethi lamanje eliqondile.
Isebenzisa i-miniUSB ejwayelekile ukuxhumana kwayo nekhompyutha ukuyifaka kuhlelo noma ukuyinika amandla.
Ukusetshenziswa kwayo kwamandla yi-19mA.
Usayizi we-PCB ngu-18x45mm ngesisindo esingu-7 gram kuphela.

I-pinout ne-datasheet

Kulomfanekiso umusa ka-Arduino ungabona i-pinout noma ukubekwa kwezikhonkwane nokuxhuma ongakuthola kuleli bhodi lokuthuthuka. Njengoba ukwazi ukubona, i-Arduino Nano ayinazo izikhonkwane eziningi ze-I / O njengodadewabo, kepha inenombolo enkulu yamaphrojekthi amaningi.

Uma ufuna ukubona imininingwane eminingi, ungafinyelela ama-datasheet akhona kule nguqulo ye-Arduino Nano:

Umehluko namanye amabhodi we-Arduino Mini ne-Micro

Ngaphakathi ama-Arduino asemthethweni Ungathola lezo zinguqulo ebesikhuluma ngazo kule bhulogi, njenge-UNO, Mega, njll. Enye futhi le yi-Arduino Nano, enokuhluka okulandelayo okubonile ezigabeni ezedlule.

Noma kunjalo, ukwenza isifinyezo esivelele kunazo zonke, lawa abaluleke kakhulu maqondana namanye amapuleti amancane asemthethweni:

Yenzelwe ngenhloso efanayo ne-Arduino Mini, yiNano kuphela ene- imbobo ye-miniUSB ukuluhlela bese ulondla ngamandla.
Su intengo kuphakathi kwe-Arduino Mini ne-Arduino Micro.
Zonke ezinye izici zingabonakala kokulandelayo ibhodi:

Ukuhambisana

Ibhodi le-Arduino Nano iyahambisana nazo zonke izinhlobo zezinto ze-elekthronikhi njengamanye amapuleti. Akukho mkhawulo wanoma yiluphi uhlobo olwedlula umkhawulo wamanje wamandla namandla osekelayo. Kepha ngaphandle kwalokho, ungasebenzisa noma iyiphi into oyifunayo konke kubonakala ku-HwLibre.

Qalisa nge-Arduino Nano

Njengoba ngishilo, ungasebenzisa isoftware efanayo ukwenza uhlelo futhi uqalise ngaleli bhodi lezentuthuko. Ngakho-ke, i-Arduino Nano ingasetshenziswa nesoftware efanayo I-Arduino IDE esetshenziselwa amanye amapuleti. Usuyazi vele ukuthi le software iguquguquka kalula futhi ikuvumela ukuthi usebenzise amabhodi wokuthuthukisa ahlukile angama-Arduino ...

Ukuqala ngesibonelo sendlela yokuhlela i-Arduino Nano, ungasebenzisa okulandelayo isikimu se-elekthronikhi ukuxhuma elula Isikrini se-LCD futhi ukwazi ukukhombisa umyalezo kuleli puleti:

Yize ipuleti elivela kulo mdwebo noFritzing LIMUNYE, kuyafana nakuNano, kufanele nje uyixhume kuzikhonkwane ezihambisanayo ... Okusho ukuthi, ungaxhuma okulandelayo:

RS LCD ukuze Nano pin D12.
I-LCD Nika amandla i-D11 kusuka ku-Nano.
I-Nano LCD D4 iye ku-D5.
I-Nano LCD D5 iye ku-D4.
I-Nano LCD D6 iye ku-D3.
I-Nano LCD D7 iye ku-D2.
I-LCD VO ekunikezelweni kwamandla ka-5v. Kulo mugqa kufanele ubeke i-10k Resistor evela esithombeni.
Ngakolunye uhlangothi, kufanele futhi uxhume i-GND ye-LCD ne-GND yebhodi.
Usuyazi vele ukuthi izikhonkwane ze-LCD 15 no-16 zizoshintsha ukukhanya kwesikrini bese zihamba ne-potentiometer ukulawula.

Ngokuqondene ne ikhodi emfushane, ungasebenzisa lesi sibonelo esilandelayo ukuqala ukubona ukuthi sisebenza kanjani. Khumbula ukusebenzisa ilabhulali yeLiquidCrystal yezikrini ze-LCD. Ungabona imininingwane eminingi enkambweni yethu yamahhala yohlelo lwe-Arduino.

#include &lt;LiquidCrystal.h&gt; //No olvides descargar la biblioteca

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {

//Configurar el número de columnas y filas del LCD

lcd.begin(16, 2);

//Imprimir mensaje en la LCD

lcd.print("¡HOLA MUNDO!");
}

void loop() {

//Poner el cursor en la columna 0, línea 1

lcd.setCursor(0, 1);

//Imprimir el número de segundos desde reset

lcd.setCursor(0, 1);  
lcd.print(millis() / 1000);

}
