Lilypad: duk game da ƙaramin kwamitin Arduino

Akwai varios arduino "dadin dandano", don yin magana. Baya ga Arduino UNO da babban wansa Mega Arduino, akwai ƙarin waɗannan faranti. Wasu da kebantattun halaye na musamman don gamsar da dukkan bukatun masu yinta. Wannan hanyar zasu daidaita da kowane irin ayyukan DIY. Wani daban daga abubuwan da aka ambata a baya shine Lilypad.

Lilypad karamin ƙaramar hukumar buɗe ido ce kuma tare da wasu halaye kwatankwacin farantin Arduino UNO tushe.

Menene Lilypad?

Ofaya daga cikin ƙananan na'urori waɗanda suka yi nasara a cikin al'ummar DIY sune kayan sawa. Wato, a cikin Sifaniyanci za su zama na'urorin "wearable", kodayake ba shi da kyau sosai. Kamar yadda zaku iya tunanin, idan baku sani ba tukun, su na'urori ne waɗanda za'a iya amfani dasu azaman tufafi ko kayan haɗi. Tabbas kun riga kun ga wasu kayan sawa kamar su agogo masu kyau, T-shirt, huluna, da sauransu, waɗanda ke da wasu nau'ikan lantarki don nuna saƙonni, fitar da wasu sigina, da sauransu.

Da kyau, don wannan nau'in na'urar ba shi da amfani don amfani da Arduino UNO, Mega, da dai sauransu, tunda sune allon babban girma, wanda tare da irin karfin da wadannan allunan suke yawanci bukata, zai sa aikin gina kayan sawa ba zai yiwu ba mai hankali. Wannan shine dalilin da yasa aka ƙirƙiri allon kamar Lilypad, wani maɓallin maɓalli a cikin tsarin halittun Arduino.

Saboda haka, Lilypad flora ba komai bane face kwamitocin ci gaba wadanda ke baiwa masu yin aiki daidai da yadda sauran allon suke, amma tare da ƙarami da damar haɗakar da keɓaɓɓen wutar lantarki, kamar ƙarami madannin maballin.

A cikin wannan labarin zan rufe LilyPad da Flora, tunda duka ayyukan suna da ban sha'awa don ƙirƙirar su tufafi masu ma'amala ko ƙananan kayan haɗi kamar iyakoki tare da fitilu, agogon ka na wayo (a salon Fitbit, Appel iWatch, Samsung Galaxy Gear…) T-shirts masu amsa abubuwan da suka faru a shafin Twitter, masu takalmin motsa jiki wanda ke yin martani ga matakai, ko kuma duk abin da zaku iya tunani.

Hakanan, ya kamata ku sani cewa al'umma da sauran masana'antun sun haɓaka kowane irin karin ayyukan da zaku iya amfani dasu da ƙari da yawana'urori masu auna firikwensin, LEDs, masu aiki, ...) waɗanda ke aiki tare da waɗannan faranti don faɗaɗa ƙarfinsu fiye da na tushe.

LilyPad / Flora halaye na fasaha

Wannan LilyPad / Flora farantin An tsara shi musamman don tufafi da yadi, kayan sawa na Arduino kamar yadda na faɗa. Leah Buechley da SparkFun Electronics ne suka kirkireshi. Gaskiya ne cewa halayen ba su da ƙarfi kamar sauran allon Arduino, amma ya fi sauƙi da raguwa, halayen da sauran allon ba su da shi.

An fara shirin tare da Arduino IDE

para shirin Flora da LilyPad daidai yake da yi da shi Arduino UNO, da dai sauransu Ana amfani da yaren shirye-shirye iri ɗaya da mahalli iri ɗaya na ci gaba, wato, IDE na Arduino. Bambanci kawai wanda dole ne ku tuna shi ne cewa dole ne ku zaɓi nau'in farantin don shirin a cikin menu IDE, tunda da tsoho zai zama UNO.

para zabi farantin da kyau a cikin Arduino IDE:

• Lily Pad: je zuwa Arduino IDE, sannan zuwa Kayan aiki, sannan zuwa ɓangaren Boards kuma can zaɓi allon LilyPad. Tare da tsarin FTDI da aka haɗa da kebul daga PC zuwa microUSB, zaka iya wuce zane don barin shi a tsara.
• Flora: je zuwa Arduino IDE, sannan Fayil, sannan Zabi. A cikin Saitunan shafin, nemi "Manajan ƙarin URL ɗin farantin faifai" kuma a can manna wannan mahadar. Af, idan kun riga kun sami wani URL a wannan fagen, yi amfani da wakafi don raba wannan sabon URL ɗin da kuka ƙara kuma kada ku goge tsohuwar, ko danna gunkin kusa da akwatin rubutu kuma ƙara sabon URL ɗin a ƙarƙashin ɗayan ɗaya a cikin sabon taga wanda ya bayyana. Da zarar ka gama, danna OK ka gama. Yanzu je zuwa Kayan aiki, Kwamitin, manajan Kati, kuma zaɓi Gudummawa daga jerin abubuwan da aka zazzage Nau'in, bincika injin binciken "Adafruit AVR" ba tare da ambato ba kuma da zarar an girka. Da zarar kun gama, zaku iya komawa zuwa menu na Kayan aiki, LilyPad Arduino Board kuma a ciki zaku iya zaɓar Adafruit Flora wanda zai bayyana bayan girka wannan kayan aikin. Anan kai tsaye ka haɗa USB ɗin zuwa microUSB kebul daga allon, ba tare da buƙatar wani sabon rukunin ba.

Sauran hanyoyin zasu kasance daidai da na kowane kwamitin Arduino, la'akari da hakan wadatar kayan aiki, wanda zai zama karami ... Misali, don ƙyafta hasken LED ɗin da zaka haɗa zuwa pin 6 na LilyPad / Flora, zaka iya amfani da lambar misali mai zuwa:

const byte pinLed6 = 6;
