velleman KA12 Analogi Input Extension Shield
Mawu Oyamba
Arduino UNO ™ ili ndi zolowetsa 6 za analogi koma mapulojekiti ena amafuna zina. Za example; sensa- kapena ntchito za robot. Chishango chowonjezera cha analogi chimangogwiritsa ntchito mizere 4 ya I/O (3 digito, 1 analogi) koma imawonjezera zolowetsa 24, kotero muli ndi zolowetsa 29 zomwe muli nazo.
Mawonekedwe:
- Zowonjezera 24 za analog
- mizere 4 ya I/O yokha ndiyomwe imagwiritsidwa ntchito
- kapangidwe kokhazikika
- wathunthu ndi library ndi examples
- imagwira ntchito ndi Arduino UNO™ ndi ma board ogwirizana
Zofotokozera:
- zolowetsa analogi: 0 - 5 VDC
- amagwiritsa ntchito zikhomo: 5, 6, 7 ndi A0 pa bolodi la Arduino UNO™
- kukula: 54 x 66 mm (2.1" x 2.6")
M'bukuli, tifotokoza momwe tingasonkhanitsire KA12 ndi momwe mungayikitsire laibulale ya Arduino yokhala ndi ex.ampndi sketch.
Zomwe zili m'bokosi
- 1 X PCB
- 1 X 470 Ohm resistor (yachikasu, yofiirira, yofiirira)
- 2 X 100k Ohm resistor (bulauni, wakuda, wachikasu)
- 2 X ceramic multilayer capacitor
- 3 X resistor gulu 100k
- 1 X 3 mm LED yofiira
- 4 X IC chosungira (mapini 16)
- 4 X pinheader yokhala ndi mapini 6 × 3
- 2 X 8 pini chamutu chachikazi
- 2 X 6 pini chamutu chachikazi
- 2 X 3 pini chamutu chachikazi
- 3 X IC - CD4051BE
- Mtengo wa 1 X IC-SN74HC595N
Malangizo omanga
- Ikani 470 Ohm resistor monga momwe tawonetsera pa chithunzi ndi solder. R1: 470 Ohm (wachikasu, wakuda, wofiirira)
- Ikani ma resistor awiri a 100k Ohm monga momwe akuwonetsera pachithunzichi ndikugulitsa. R2, R3: 100k Ohm (bulauni, wakuda, wachikasu)
- C1, C2: ma carmic multilayered capacitors
- RN1, RN2, RN3: resistor array 100k
- Kuwala kwa LED: Kuwala kwa LED kofiira Ganizirani polarity!
- IC1, ..., IC4: Ogwira IC Ganizirani za komwe akupita!
- Solder onse 6 × 3 pinheader zolumikizira. Onetsetsani kuti zikhomo zopindika zagulitsidwa!
- Solder onse 6 pini mitu yachikazi ndi 8 pini mitu yachikazi mu malo. Osadula zikhomo!
- SV1: mitu iwiri ya 3 pini ya akazi
Ikani zikhomo kumbali ya solder ndi solder kumbali ya chigawocho!
Onetsetsani kuti pamwamba pamitu mwawongoleredwa mofanana ndipo musapitirire pamwamba pa zikhomo zina. Mwanjira iyi, idzakwanira bwino pa Arduino Uno wanu.
Osadula zikhomo! - IC1, IC2, IC3: IC - CD4051BE Ganizirani mayendedwe a notch! Iyenera kufanana ndi notch yomwe ili pa IC!
- IC4: IC - SN74HC595N Ganizirani za mayendedwe a notch! Iyenera kufanana ndi notch yomwe ili pa IC!
Zogwirizana ndi KA12
Ndikofunika kwambiri kuyika KA12 molondola pa Arduino Uno kuti mupewe kuwonongeka kwa zikhomo ndikuonetsetsa kuti pali kulumikizana kwabwino. Nazi mfundo zofunika kwambiri:
- A. Mutu wachikazi wamapini 6 uwu ukulowa ndendende mu 'ANALOG IN' pa Arduino.
- B. Mitu iwiri ya mapini atatu aakazi amatsetsereka pa mapini 3 a ICSP pa Arduino.
- C. Manambala omwe ali pambali pa mitu 8 ya akazi pa KA12 ayenera kugwirizana ndi Digital I/O's.
- D. Sungani mapini mosamala mu Arduino kuti musawonongeke.
Kukhazikitsa Library ya Arduino
Ikani laibulale:
Pitani patsamba lotsitsa la KA12 pa Velleman webtsamba:
http://www.vellemanprojects.eu/support/downloads/?code=KA12
Tsitsani kuchotsa kwa 'velleman_KA12' ndikukopera chikwatu cha "velleman_KA12" kumabuku anu a Documents\Arduino\libraries.
Exampndi sketch:
- A. Tsegulani pulogalamu ya Arduino
- B. Kenako dinani file/Eksamples/Velleman_KA12/Velleman_KA12
Kodi:
Mzere ndi mzere
- Kuti ntchito za KA12 zikhale zosavuta kugwiritsa ntchito, tidapanga laibulale. Mzere 1 ndi 6 lengezani kugwiritsidwa ntchito ndikuyambitsa laibulale. Izi ziyenera kuchitidwa muzojambula zilizonse zomwe zimagwiritsa ntchito KA12. Laibulale imakupatsani mwayi wowerengera mosavuta ma sensor onse ndikusunga mu int-array kapena kuwerenga mtengo umodzi ndikusunga izi ku int.
- Kuti muwerenge masensa onse muyenera kulengeza int-array ndi malo 24 (mzere 2). Kudzaza mndandanda timagwiritsa ntchito readAll command (mzere 8). Mu example timawonetsa zikhalidwe zonse ku serial monitor pogwiritsa ntchito loop (mzere 9 mpaka 12). Kuyankhulana kosalekeza kumakhazikitsidwa pamzere wa 5. Ngati mukufuna mtengo umodzi wokha mungagwiritse ntchito lamulo la "ka12_read" (mzere 13).
