Zambiri Zazidziwitso Zamphamvu Zoyendetsa Neon Arduino

Dynamic Neon Arduino Driven Sign ndi chizindikiro cha DIY LED chomwe chimatha kuwonetsa ma groovy osiyanasiyana. Chizindikirocho chimapangidwa pogwiritsa ntchito zingwe za neon za LED, Arduino Uno microcontroller board, NPN transistor, block terminal, toggle switch, nkhuni zamapepala, zomangira, ndi magetsi a 12V DC. Chizindikirocho chingagwiritsidwe ntchito kuwonetsa zilembo zamtundu uliwonse pazochitika, masitolo, kapena nyumba.

Malangizo Ogwiritsira Ntchito Zogulitsa

Khwerero 1: Jambulani Mapangidwe
Poyamba, sankhani kapangidwe kake kuti mawuwo awonetsedwe. Sankhani font yomwe ilibe ma curve othina kwambiri chifukwa zimakhala zovuta kupindika chingwe cha LED mozungulira. Lembani mapangidwe osankhidwa pa bolodi lakumbuyo ndikufufuza zilembo ndi pensulo. Sungani nyama zosokera kunja kwa chipindacho kuti izi zifulumire. Ngati palibe mwayi wopeza purojekitala, sindikizani zilembozo papepala ndikuziyika pa bolodi kapena mwaulere. Kuti muyambe, muyenera kusankha kapangidwe kanu ka mawu omwe mukufuna kuwonetsedwa. Mutha kupeza mafonti amitundu yonse pa intaneti koma nthawi zambiri mumafuna china chake chomwe sichikhala ndi ma curve olimba kwambiri chifukwa zimakhala zovuta kupindikiza chingwe cha LED. Ndapeza font iyi kukhala yoyenera kwambiri pazosowa zanga.  https://www.fontspace.com/sunset-club-font-f53575 Mukasankha pulojekiti yojambula pa bolodi lanu lakumbuyo, kwa ine inali pepala la OSB. Kenako fufuzani zilembozo ndi pensulo. Kusunga nyama zosokera kunja kwa chipindacho kudzafulumizitsa ntchitoyi. Ngati mulibe mwayi wogwiritsa ntchito projekiti mutha kusindikizanso zilembozo papepala ndikuzimamatira pa bolodi kapena kungoziika pamanja.

Khwerero 2: Gwirizanitsani Zingwe za LED
Kenako, dulani tepi ya LED kukhala mizere pagawo lililonse la zilembo. Dulani tepiyo pamalo enieni kuti ma LED onse agwire ntchito, nthawi zambiri pambuyo pa LED iliyonse yachitatu. Pangani tatifupi kuti tigwire pazingwe ndikuzilumikiza ku backboard ndi zomangira zazing'ono. 3D Sindikizani zidutswazo, kapena gwiritsani ntchito tatifupi tazingwe kapena misomali kuti musunge mizereyo. Pang'onoting'ono 'i,' dulani gawo la silikoni mozungulira ma LED ndikuphimba ma LED angapo kuti mupange kusiyana ndi kadontho pamwamba pa chilembocho.

Tsopano muyenera kudula tepi ya LED kukhala mizere pagawo lililonse la zilembo. Ngati munagwirapo ntchito ndi tepi ya LED musanadziwe kuti muyenera kudula tepiyo pamalo enieni kuti ma LED onse agwire ntchito, kawirikawiri pambuyo pa LED iliyonse yachitatu. Izi zikutanthauza kuti mungafunike kupanga mizere yayifupi pang'ono kapena yayitali kuposa gawo lomwe mwangopeza kumene, koma ndikusokoneza pang'ono ndikusuntha zinthu mozungulira mutha kupanga chizindikirocho kukhala chabwino. Ndidapanga zomata pa fusion 360 kuti zigwiritsire ntchito zingwe ndikuzilumikiza ku bolodi lakumbuyo ndi zomangira zing'onozing'ono, mutha kusindikiza 3D momwe mungafune. Ndi ang'onoang'ono kwambiri mwachangu komanso osavuta kusindikiza. Ngati mulibe chosindikizira cha 3D mutha kungogwiritsa ntchito tatifupi tazingwe kapena misomali kuti mugwire zingwezo. Kwa kachingwe kakang'ono 'i' mutha kudula gawo la silikoni mozungulira ma LED ndikuphimba ma LED angapo kuti mupange kusiyana ndi kadontho pamwamba pa chilembocho.

Khwerero 3: Yambani ma LED
Monga chizindikirocho chimatha kuyatsa zilembo payekhapayekha, gwirizanitsani mawaya kuchokera ku chilembo chilichonse kupita kumalo amodzi kumbuyo kwa bolodi. Boolani dzenje kumapeto kwa gawo lililonse la mizere ya LED ndikugulitsa utali wa waya wawiri ku 12V ndi GND pamzere uliwonse. Dulani mbali ina kudzera mu dzenje laling'ono. Konzani waya wopanda kanthu m'mbali mwa mbali yakumbuyo kwa bolodi kuti muchepetse kuchuluka kwa ma cabling ofunikira. Lumikizani mawaya onse abwino kwa icho, ndikupangitsa chizindikiro chonsecho kukhala ngati chiwonetsero cha LED cha anode 7. Bweretsani mawaya onse wamba ndikulumikiza payekhapayekha ku block block. Gwirizanitsani pamodzi mawaya wamba a zilembo zomwe zili ndi zigawo zingapo, monga chilembo M. Masitepe onsewa akatsatiridwa bwino, Chizindikiro Choyendetsa cha Dynamic Neon Arduino ndichokonzeka kugwiritsidwa ntchito monga momwe wosuta amafunira.

Monga chizindikiro chimatha kuyatsa zilembo payekhapayekha muyenera kulumikiza mawaya kuchokera ku chilembo chilichonse kupita ku mfundo imodzi kumbuyo kwa bolodi. Kumapeto kumodzi kwa chigawo chilichonse cha mizere ya LED, boolani dzenje lalikulu kuti chingwe chidutse. Solder kutalika kwa waya wapawiri kwa 12V ndi GND pa mzere uliwonse ndi kudutsa mapeto ena anaganiza dzenje laling'ono. Kuti ndichepetse kuchuluka kwa ma cabling omwe amafunikira ndinakonza waya wopanda kanthu kutalika kwa mbali yakumbuyo ya bolodi ndikulumikiza mawaya onse abwino, motero ndikupangitsa chizindikiro chonse kukhala ngati chiwonetsero cha anode 7 gawo la LED. Mawaya onse odziwika amabweretsedwa ndikulumikizidwa payekhapayekha ku block block. Zilembo zina zimakhala ndi zigawo zingapo monga chilembo M, mawaya wamba a izi akhoza kuikidwa pamodzi. Mawaya onse amatha kuphimbidwa ndi tepi kuti atetezedwe kuti asagwedezeke, komanso kuti awoneke bwino. Kumbuyo kwa chiwonetserochi kumawoneka ngati kopanda pake, koma kudapangidwa nthawi yayitali ndipo palibe amene angawone izi kupatula inu.

Gawo 4: Kuzungulira

Arduino Uno imagwiritsidwa ntchito kuwongolera chilembo chilichonse, komabe zikhomo za GPIO pa Arduino sizingathe kumira kapena kupatsa mphamvu ma LED, chifukwa chake madalaivala ena owonjezera amafunikira. Chosinthira chakumbali chotsika cha transistor chingagwiritsidwe ntchito kuyatsa ndi kuzimitsa zilembo. Wosonkhanitsa amalumikizidwa ndi mbali yotsika ya chilembo chilichonse, emitter pansi ndi maziko a pini iliyonse ya GPIO ya Arduino kudzera pa 1k resistor. Kutsatira chithunzi cha dera mutha kuphatikiza masiwichi ambiri a transistor momwe muli ndi zilembo pachikwangwani chanu. Ndinapanga bolodi lakumutu ndi ma transistors kuti agwirizane bwino pamwamba pa Arduino. Ngati mukufuna zilembo zambiri kuposa Uno ali ndi zikhomo za GPIO mutha kukweza kukhala Arduino Mega kapena kugwiritsa ntchito chowonjezera cha IO monga MCP23017. Chingwe cha 12V chomwe chimapita kuzingwe zonse za LED chimalumikizidwa kumbuyo kwa pini yabwino ya cholumikizira mbiya pa Uno. Mwanjira iyi magetsi amodzi a 12V DC angagwiritsidwe ntchito pa ma LED ndi Arduino, onetsetsani kuti zomwe mwasankha zitha kupereka ma LED onse. Zakale zomaliza za zozungulira ndikulumikiza switch ya SPDT On-Off-On kuti musinthe pakati pamitundu yosiyanasiyana. Zomwe zimasinthidwa zimalumikizidwa ndi GND ndipo zikhomo zina ziwiri zimalumikizidwa mwachindunji ku A1 ndi A2 ndipo zitenga advan.tage wa mkati kukoka resistors pa zikhomo izi. Ndinapanganso mpanda womwe ukhoza kusindikizidwa ndi 3D ndikumangirira kumbuyo kwa Arduino kuti ikhale ndi chitetezo pang'ono.

Gawo 5: Mapulogalamu

Tsopano chizindikirocho chapangidwa ndipo zamagetsi zolumikizidwa, Arduino ikhoza kukonzedwa kuti ipange mawonekedwe a groovy. Khodiyo ndiyosavuta, ndalemba ntchito zingapo zowunikira chikwangwanicho m'njira zosiyanasiyana monga kusuntha mbali ndi mbali, mawu akuthwanima ndikuyatsa ndi kuzimitsa zilembo zosiyanasiyana. Ngati mukugwiritsa ntchito mawu osiyanasiyana pachizindikiro changa muyenera kusintha pulogalamuyo pang'ono kuti magwiridwewo adziwe zomwe zikhomo za IO zimayikidwa pa liwu lililonse. Pakukhazikitsa kwanga kulumikizana kwa IO ku zilembo ndi 4 = 'K', 5 = 'e', ​​6 = 'y'… Kuyambitsa kwa code kumakhazikitsa ma pin onse a digito omwe amawongolera zilembo ku zotuluka ndi mapini awiri a analogi olumikizidwa chosinthira ngati zolowetsa ndi chokoka chamkati. A3 imasiyidwa kuyandama kotero kuti ingagwiritsidwe ntchito ngati mbewu yopangira manambala mwachisawawa.

Lupu lalikulu kenako limawerenga momwe kusinthaku kulili ndipo kumayendetsa imodzi mwazosankha zitatu kutengera komwe akulowera. Itha kuyatsa ma LED onse, kuzungulira mosasintha kapena kusinthana pakati pa zonse kwa masekondi 60 ndi mapatani masekondi 60. Apanso popeza mukugwiritsa ntchito mawu osiyanasiyana muyenera kusintha ntchito zomwe zimawunikira mawu amodzi, izi zitha kupezeka pansi pa code.

Gawo 6: Zonse Zatheka!
Pomaliza muyenera kukhala ndi chidutswa chachikulu chapakati kuti chiwonetsedwe m'malo amitundu yonse. Zosintha zamtsogolo - kutengera zomwe ndalandira zitha kukhala zothandiza kuwongolera kuwala kwa chizindikiro. Izi zitha kuchitika pogwiritsa ntchito chosinthira cha P cha MOSFET kumbali yakumtunda kwa ma LED ndikuchilumikiza ku imodzi mwamapini a PWM pa Arduino, kusinthasintha kwa ntchito kumatha kusintha kuwala. Ngati ndimaliza kukhazikitsa izi ndisintha malangizo awa.
