• Screwdrivers
• Dziwani zida zanu ndikutsatira njira zomwe mwalangizidwa ndikuwonetsetsa kuti mwavala PPE yoyenera.
• Palibe mgwirizano kwa ogulitsa omwe agwiritsidwa ntchito mu polojekitiyi, omasuka kugwiritsa ntchito omwe mumawakonda ndikulowetsa zinthu zomwe zinali zoyenera malinga ndi zomwe mumakonda kapena zomwe mungapereke.
• Maulalo ndi ovomerezeka panthawi yofalitsidwa.
• Khwerero 1: Zovala za Baseplate
• Onani: Modular Display Element (MDE)
• "Zinthu Zinayi Zowonetsera" zimafunikira kuti apange chiwonetsero cha wotchi ndipo izi zimagwiridwa limodzi ndi zingwe zomata zomwe zidadulidwa kuchokera pachidebe chachikulu.
• Mizere yoyambira pansi imayesa 32 (W) x 144 (L) mm kapena 4 x 18 stubs ndipo iliyonse imadutsa ma MDE awiri omwe amamangiriridwa pazitsulo za MDE. Komabe, kuti muwonjezere mphamvu zomangira zinayi za M2 x 8mm zimayikidwa pafupi ndi ngodya zomwe zimadutsa pansi ndikulowa mu MDE.
• Gawo 2: Schematic
• Chiwembuchi chikuwonetsa zigawo zomwe zimagwiritsidwa ntchito kuwongolera ma MDE omwe ali ndi 56 Neopixels.
• Zida zowongolera zimakhala ndi Microbit, RTC, Breakout Board, switch and chitetezo dera.
• Zambiri mwazogulitsa zimayang'ana pa Neopixels pomwe zida zowongolera zimalumikizidwa makamaka ndi ma jumper.
• Gawo 3: Coding
• Code imapangidwa mu MakeCode.
• "oonn ssttaarrtt" pprroocceedduurree..
• Imayambitsa mzere wa Neoplxel wa ma LED 56
• Onetsani uthenga wamutu.
• Imayambitsa segment_list yomwe ili ndi magawo pa nambala yomwe ikuwonetsedwa. Nambala 0 yosungidwa mu chinthu [0] = 0111111
• Nambala 1 yosungidwa mu chinthu [1] = 0000110
• Nambala 9 yosungidwa mu chinthu [9] = 1101111
• Kuphatikiza apo.
• Nambala 10 yosungidwa mu element [10] = 0000000 yogwiritsidwa ntchito pobisa manambala.

nthawi zonse ndondomeko

• Imayimba 'set mode' yomwe imayang'ana P1 ndipo ngati yayitali imathandizira kukhazikitsa nthawi kukuwonetsa nthawi yomwe ilipo.
• Imayitana 'Time_split' yomwe imalumikiza manambala awiri a maola ndi mphindi kukhala zingwe za zilembo 4, kuyikatu manambala aliwonse osakwana 10 ndi ziro patsogolo.
  Imayimba 'pixel_time'
• Zomwe zimachotsa zilembo 4 zilizonse kuyambira ndi womaliza kukhala segment_value
• Digit ndiye ili ndi mtengo mu segment_list yotchulidwa ndi segment_value.
• (Ngati gawo_value = 0 ndiye manambala = chinthu [0] = 0111111)
• Inc = index x (LED_SEG) x 7). Pomwe index = iti mwa zilembo 4 zomwe zatchulidwa, LED_SEG = kuchuluka kwa ma LED pagawo lililonse, 7 = kuchuluka kwa magawo mu digito.
• Mtundu uwu ndi chiyambi cha ma LED oti aziwongoleredwa pamtundu woyenera.
• The for element imagawira nambala iliyonse mu digito kuti ikhale yamtengo wapatali.
• Ngati mtengo = 1 ndiye kuti pixel yoperekedwa ndi inc imayikidwa kuti ikhale yofiira ndikuyatsidwa apo ayi imasinthidwa o.
• Monga ma LED awiri pagawo amafunikira njirayi imabwerezedwa nthawi za LED_SEG.
• (Mwachitsanzo, ngati unit ya Maola ndi 9, index = 0, digit = 1011111 [mtengo = 1, inc = 0 & inc = 1], [value=0, inc = 2 & inc = 3] .... [value=1, inc=12 & inc = 13])
• Maola khumi [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].
• Chilichonse mwazinthu 7 zikasinthidwa ndikutumizidwa pamzere zosintha zikuwonetsedwa.
• Kuchedwa kumayambitsidwa kuti mupewe icker.
• pa batani AA"
• Izi zimayika maola ngati set_enable = 1
• batani BB”
• Izi zimayika mphindi ngati set_enable = 1 "buutttoonn yayitali AA++BB"
• Izi zimayimba 'nthawi yoikika' yomwe imayika nthawi kutengera zomwe zaperekedwa ndi mabatani A ndi B.

Gawo 4: Back Panel
Zidazi zimamangiriridwa ku baseplate (95(W) x 128(L) mm), yomwe imayikidwa kumbuyo kwa MDE ndi M3 X 25mm bolts ndi 10mm standos. Mabawuti anayi amaikidwa m'mabowo mu bolodi lothandizira la Neopixel ndipo zoyimirira zomangirira pansi pamakona, mabowo a 3mm amapangidwa m'munsi kuti agwirizane ndi mabawuti. Malo ndi kubowola mabowo a Edge cholumikizira Breakout (2 x 3mm), RTC (2 x 2mm), ndi chosinthira kuwonetsetsa kusiya malo (20 x 40mm), kuti akweze mabulaketi a ngodya yakumanja omwe amakhala ngati mapazi. Malumikizidwe ku RTC amapangidwa ndi 4 Junior jumpers F/F ndipo RTC imakhala yotetezedwa ndi 2 x M2 bolts. Kulumikizana ndi switch kumapangidwa ndi 2 Junior jumpers F/M ndipo chosinthira chimayikidwa kudzera pabowo la 5mm. Kulumikizika kudera lachitetezo cha CR kwa Neopixels kumapangidwa ndi 3 Jumpers F/F ndipo kuchokera pano kupita ku Neopixels okhala ndi 3 jumpers F/M, izi zimamangiriridwa pa bolodi ndi tayi ya chingwe yodyetsedwa kudzera m'mabowo amodzi pa bolodi.
Gwirizanitsani phazi lopindika kuchipinda choyambira ndi mabawuti 4. (Maboliti akumunsi a M3 ophatikizira pansi angagwiritsidwe ntchito kuyika mapazi m'malo mwake ndi bawuti ya 2 pabowo lakumunsi la bulaketi. Kuti mupewe kukanda pamalo pomwe wotchiyo ikhala, phatikizani ndodo pa mapepala kapena angapo. Tepi yokhotakhota: Baseplate tsopano ikhoza kuyikidwa pamaboti akona ndikumangirizidwa ndi mtedza.

• Gawo 5: Ntchito
• Mphamvu imaperekedwa polumikiza chingwe cha USB mwachindunji ku Microbit.

• Koloko yabwino. Ndimakonda kuti izi zimachokera ku Micro:bit!
• Zikomo, The Micro:bit ndi yosinthika kwambiri ndakhala ndikugwiritsa ntchito muma projekiti anga ambiri.
