• Inogona kuratidza kuti inodhura zvakanyanya kutenga huwandu hwehukoshi kwete hwemunhu wega kunze kwekunge watova nazvo zviripo. Zvimwe zvikamu zvinogonawo kuva neMOL yakakura kudarika huwandu hunotsanangurwa muchikamu chechikamu.
• 3D Printer
• White Filament - Kune yakanyanya kuratidza kugona.
• Black Filament - Yemabhodhi anotsigira.
• 2mm kubhururuka zvishoma
• 3mm kubhururuka zvishoma
• 5mm chibooreso kit
• Drill
• Saw
• Pliers
• Wire cutters
• Soldering Iron
• Solder
• Kusona bepa
• Zvikurisa
• Ziva maturusi ako uye uteedzere maitiro akakurudzirwa uye uve nechokwadi chekupfeka PPE yakakodzera.
• Hapana mubatanidzwa kune chero wevatengesi vanoshandiswa mupurojekiti iyi, inzwa wakasununguka kushandisa vatengesi vaunofarira uye chinja zvinhu izvo zvaive zvakakodzera zvaunoda iwe pachako kana zvichienderana nekupa.
• Malink anoshanda panguva yekuburitswa.
• Danho 1: Baseplate Strips
• Ona: Modular Display Element (MDE)
• Ina "Modular Display Elements" inodiwa kugadzira wachi kuratidza uye izvi zvinobatwa pamwe chete nebaseplate mitsetse iyo yakachekwa kubva kune hombe baseplate.
• Iyo baseplate mitsetse inoyera 32 (W) x 144 (L) mm kana 4 x 18 stubs uye imwe neimwe inodarika maviri MDE inonamatira kune stubs paMDE. Nekudaro, kune akawedzera simba mana M2 x 8mm screws akaiswa padyo nemakona ayo anopfuura nepakati baseplate uye achipinda muMDE.
• Danho 2: Schematic
• Iyo schematic inoratidza zvikamu zvinoshandiswa kudzora maMDE ayo ane 56 Neopixels.
• Izvo zvikamu zvekutonga zvinosanganisira Microbit, RTC, Breakout Board, Shandura uye yekudzivirira dunhu.
• Iyo yakawanda ye soldering yakatarisana neNeopixels nepo zvinhu zvekutonga zvinonyanya kubatanidzwa nejumpers.
• Danho rechitatu: Coding
• Code yakagadzirwa muMakeCode.
• "oonn ssttaarrtt" pprroocceedduurree..
• Inotanga Neoplxel tambo ye56 LEDs
• Ratidza meseji yemusoro.
• Inotangisa iyo segment_list iyo ine segment mazita panhamba icharatidzwa. Nhamba 0 yakachengetwa muchikamu [0] = 0111111
• Nhamba 1 yakachengetwa muchikamu [1] = 0000110
• Nhamba 9 yakachengetwa muchikamu [9] = 1101111
• Uyezve.
• Nhamba yegumi yakachengetwa muchikamu [10] = 10 inoshandiswa pakuvhara digit.

zvachose maitiro

• Inofona 'set modhi' inotarisa P1 uye kana yakakwirira ichigonesa nguva kuseta neimwe nzira inoratidza nguva iripo.
• Inodaidza 'Time_split' iyo inojoinha nhamba mbiri dzemaawa nemaminetsi kuita tambo ine mavara mana, pre-xing chero manhamba ari pasi pegumi aine ziro inotungamira.
  Inodaidza 'pixel_time'
• Iyo inobvisa yega yega mavara mana ichitanga neiyo yekupedzisira muchikamu_value
• Digit inobva yatora kukosha mu segment_list inotaridzwa ne segment_value.
• (Kana segment_value = 0 then digit = element [0] = 0111111)
• Inc = indekisi x (LED_SEG) x 7). Iko index = ndeupi pamavara mana anotaurwa, LED_SEG = nhamba ye LED's pachikamu, 4 = nhamba yezvikamu mudijiti.
• Mhando iyi ndiyo kutanga kwema LED kuti adzorerwe kune hunhu hwakakodzera.
• The for element inopawo nhamba yega yega mudijiti kuti iwane kukosha.
• Kana kukosha = 1 saka pixel yakapihwa ne inc inoiswa kune tsvuku uye yakabatidzwa neimwe nzira inoshandurwa o.
• Sezvo ma LED maviri pachikamu anodiwa maitiro aya anodzokororwa LED_SEG nguva.
• (Eg Kana maawa ari 9, index = 0, digit = 1011111 [value = 1, inc = 0 & inc = 1], [value=0, inc = 2 & inc = 3] .... [kukosha=1, inc=12 & inc = 13])
• Maawa gumi [Index =1, inc range 14 to 27], Minutes unit [index =2, inc range 28 to 41], Minute's tens [index =3, inc range 42 to 55].
• Kana imwe neimwe ye7 kukosha yagadziriswa uye yakatumirwa kune iyo mitsetse shanduko dzinoratidzwa.
• Kunonoka kunounzwa kudzivirira icker.
• pabhatani AA”
• Izvi zvinoseta maawa kana set_enable = 1
• pane bhatani BB”
• Izvi zvinoseta maminetsi kana set_enable = 1 "refu bbuutttoonn AA++BB"
• Izvi zvinodana 'set time' iyo inoseta nguva zvichienderana nehunhu hwakapihwa nemabhatani A uye B.

Danho 4: Back Panel
Izvo zvikamu zvakanamirwa kune baseplate (95(W) x 128(L) mm), iyo yakasungirirwa kumashure kweMDE's neM3 X 25mm mabhoti uye 10mm standos. Mabhaudhi mana akaiswa nemumaburi ari muNeopixel bhodhi rekutsigira uye mastandos akaiswa kuti abatanidze baseplate pamakona, 3mm maburi anogadzirwa mubaseplate kuti aenderane nemabhaudhi. Nzvimbo uye buri maburi eEdge yekubatanidza Breakout (2 x 3mm), iyo RTC (2 x 2mm), uye switch inovimbisa kusiya nzvimbo (20 x 40mm), kukwidza kona yekurudyi mabhuraketi anoita setsoka. Kubatanidza kuRTC kunogadzirwa ne4 Junior jumpers F/F uye iyo RTC inochengetedzwa ne2 x M2 mabhaudhi. Kubatanidza kune switch inogadzirwa ne 2 Junior jumpers F/M uye switch inoiswa kuburikidza ne5mm gomba. Kubatanidza kune CR yekudzivirira yedunhu reNeopixels inogadzirwa ne3 Jumpers F/F uye kubva pane iyi kuenda kuNeopixels ine 3 jumpers F/M, izvi zvakanamirwa kubhodhi netambo tambo inodyiswa kuburikidza nerimwe buri mubhodhi.
Gadzirisa tsoka dzemakona ebhuraketi kune baseplate nemabhaudhi mana. (Makona epasi M4 mabhaudhi ekubatanidza baseplate anogona kushandiswa kubata tsoka panzvimbo ne 3nd bhaudhi muburi rezasi rebhureketi. Kuti udzivise kukwenya nzvimbo ichagara wachi, isa tsvimbo pamapedhi kana vaviri. mabhaudhi erutsigiro ekona uye akasungwa nenzungu.

• Danho 5: Kushanda
• Simba rinopihwa nekubatanidza USB tambo yakananga kuMicrobit.
• SSeettttiinngg ththee cclloocckk..
• Usati waseta wachi iva nechokwadi chekuti RTC ine bhatiri rakaiswa kuchengetedza nguva kana kana simba rabviswa. Iyo yakasarudzika nguva fomati ndeye 24 awa modhi.
• Fambisa switch kune yakatarwa nguva chinzvimbo chiratidzo chekuwedzera chicharatidzwa pachiratidziro.
• Dzvanya Bhatani A kwemaawa. (0 kusvika ku23)
• Dzvanya Bhatani B kweMaminitsi. (0 kusvika ku59)
  Dzvanya Mabhatani A & B pamwe chete kuseta nguva, iyo yakapinda nguva kukosha icharatidzwa.
• Fambisa switch kubva panzvimbo yakatarwa.
• AAtt sswwiittcchh oonn oorr aafftteerr sseettttiinngg.
• Mushure mekunonoka kupfupi chiratidziro chichagadziridzwa nenguva iripo
• Nhanho 6: Pakupedzisira
  Kuunganidzwa kwemapurojekiti madiki mashoma kunozokonzera chirongwa chikuru. Ndinovimba iwe neizvi uye nemapurojekiti apfuura ane hukama anofarira.

• zvinoshamisa chirongwa
• Ndatenda, ndatenda zvikuru.
• Nice project!
• Ndatenda.
• Cool wachi. Ini ndinoda kuti izvi zvinomhanya Micro: bit!
• Ndatenda, Iyo Micro: bit inoshanda zvakasiyana-siyana ini ndakaishandisa mune akawanda emapurojekiti angu ewachi.
