Gabatarwa
Arduino UNO™ an sanye shi da abubuwan shigar analog guda 6 amma wasu ayyukan suna buƙatar ƙari. Domin misaliample; ayyukan firikwensin- ko robot. Garkuwar shigar da ƙarar analog ɗin tana amfani da layukan I/O 4 kawai (dijital 3, analog 1) amma yana ƙara abubuwan shigarwa guda 24, don haka gabaɗaya kuna da abubuwan shigar analog 29 a wurin ku.
Siffofin:
- 24 kayan aikin analog
- layuka 4 I/O kawai ake amfani da su
- zane mai ɗorewa
- cikakke tare da ɗakin karatu da examples
- yana aiki tare da Arduino UNO ™ da allon jituwa
Ƙayyadaddun bayanai:
- Bayanan analog: 0 - 5 VDC
- yana amfani da fil: 5, 6, 7 da A0 akan allon Arduino UNO ™
- girma: 54 x 66 mm (2.1 "x 2.6")
A cikin wannan jagorar, za mu bayyana yadda ake haɗa KA12 da yadda ake shigar da ɗakin karatu na Arduino tare da tsohon.ampda zane.
Me ke cikin akwatin
- 1 x PCB
- 1 x 470 Ohm resistor (rawaya, shunayya, ruwan kasa)
- 2 X 100k Ohm resistor (launin ruwan kasa, baki, rawaya)
- 2 X yumbu multilayer capacitor
- 3 X tsayayyar tsararre 100k
- 1 X 3 mm ja LED
- 4 X IC mai riƙewa (16 fil)
- 4 X pinheader tare da 6 × 3 fil
- 2 X 8 fil mata na mata
- 2 X 6 fil mata na mata
- 2 X 3 fil mata na mata
- 3 X IC - CD4051BE
- 1 X IC - SN74HC595N
Umarnin gini
- Matsayi mai tsayayya na 470 Ohm kamar yadda aka nuna a hoton da mai siyarwa. R1: 470 Ohm (rawaya, baƙi, ruwan kasa)
- Matsayi masu tsayayya 100k Ohm guda biyu kamar yadda aka nuna a hoton kuma siyar dasu. R2, R3: 100k Ohm (launin ruwan kasa, baƙi, rawaya)
- C1, C2: maɓuɓɓugan ƙarfe masu yawa
- RN1, RN2, RN3: tsararren tsararren 100k
- LED: ja LED Lura da polarity!
- IC1,…, IC4: Masu riƙe da IC Hankalin jagorancin ƙira!
- Derarfafa dukkan haɗin haɗin 6 × 3. Tabbatar an lanƙwashe fil ɗin da aka siyar!
- Derarfafa duka maƙunnin mata shida da na mata 6 a cikin wuri. Kada ku yanke fil!
- SV1: biyu 3 fil shugabannin mata
Saka fil a gefen siyar da siyar a gefen bangaren!
Tabbatar cewa saman masu kai yana daidaita daidai gwargwado kuma kada ya wuce saman sauran fil ɗin. Ta wannan hanyar, zai dace da kyau akan Arduino Uno.
Kada ku yanke fil! - IC1, IC2, IC3: IC - CD4051BE Yi la'akari da shugabancin ƙira! Ya kamata ya dace da ƙididdigar mai riƙe da IC!
- IC4: IC - SN74HC595N Yi la'akari da jagorancin ƙira! Ya kamata ya daidaita da ƙididdigar mai riƙe da IC!
Haɗa KA12
Yana da matukar mahimmanci a saka KA12 daidai akan Arduino Uno don guje wa lalacewa ga fil kuma don tabbatar da kyakkyawar haɗi. Ga mahimman abubuwan kulawa:
- A. Wannan fil ɗin 6 na fil ɗin ya dace daidai da '' ANALOG IN '' akan Arduino.
- B. Shugabannin mata biyu na pin guda 3 suna zamewa akan filayen ICSP 6 akan Arduino.
- C. Lambobin da ke kusa da kanun labarai 8 na mata a kan KA12 su dace da na I/O na Dijital.
- D. Zame fil a hankali cikin Arduino don hana lalacewa.

Layi da layi
- Domin sauƙaƙe ayyukan KA12 don amfani, mun yi ɗakin karatu. Layi na 1 da 6 sun bayyana amfani da fara ɗakin karatu. Dole ne a yi wannan a kowane zane mai amfani da KA12. Laburaren yana ba ku damar sauƙin karanta duk ƙimar firikwensin kuma adana su a cikin tsararru ko karanta ƙima ɗaya kuma adana wannan zuwa int.
- Don karanta duk na'urori masu auna firikwensin ya kamata ku ayyana int-array mai wurare 24 (layi 2). Don cika tsararru muna amfani da umarnin readAll (layi 8). A cikin exampZa mu nuna duk ƙimar ga mai duba serial ta amfani da madauki (layi na 9 zuwa 12). An saita sadarwar serial a layi na 5. Idan kuna buƙatar ƙima ɗaya kawai za ku iya amfani da umarnin "ka12_read" (layi 13).
