Nov yog daim ntawv sau tseg. Kuv tseem tsis tau muaj duab …

Ua luam dej? Kawm? Ua li cas los xij, pom meej koj qhov kev sib cais.

Txoj haujlwm no yog qhov pheej yig dua ntawm MichaelH814's: instructables.com/id/Large-7-Segment-LED-Pace-Clock. Txoj haujlwm ntawd tau tshoov siab los ntawm $ 100 duas las moos los ntawm mjacobson1: instructables.com/id/100-Pace-Clock-or-Wall-Clock.

Kauj Ruam 1: Kauj Ruam 1: Ncej/kab ntawv

Txiav ntoo. Ntsia Hlau. Thov tshuaj tsuag xim.

Kauj Ruam 2: Kauj Ruam 2: Sab Hauv Pandora (Lub Thawv)

  1. Txiav 2-3 daim ua kom haum nruj hauv 12 "x 29". Txiav 28 LED strips (5-6 "dav).
  2. Siv ib lub rooj ua npuas dej ua lub thaub qab (thaub qab) rau cov hlua LED. Teeb plaub plaub 7-ntu qhia nrog qhov sib txawv ntawm qhov kawg. Nws yuav tsum mus ib yam li 0.75 "→ 6" → 7.75 "→ 13" → 14.5 "→ 16" → 21.25 "→ 23" → 28.25 ".
  3. Siv daim kab xev ob tog rau nruab nrab ntawm txhua kab ntawv LED.
  4. Kos thiab txiav plaub fab tawm ntawm pawg thawj coj ua npuas dej thib ob ua raws rau cov teeb pom kev zoo ntawm LED.
  5. Kuj txiav 1 "colons.
  6. Tsis txhob tsuag xim ua npuas ncauj! Nws yuav yaj thiab deform. Hloov chaw, pleev xim rau daim ntawv txiav nrog dub matte acrylic xim.
  7. Ua kom ntseeg tau tias cov kab hluav taws xob LED ua ke nrog cov zawj tshiab no. Kho yog tsim nyog.
  8. Nqa qhov kawg ntawm cov hlua LED thiab laum qhov ntawm lub rooj tsav tsheb tom qab.
  9. Kaw ob lub xwmfab nruab nrab ntawm txhua 7-ntu tso saib. (Cov kua nplaum twg yuav ua. E6000 yog qhov hnyav me ntsis.)
  10. Ua ntej khi cov laug cam ua ke:

    Cov tub rog 12 "cov xov hlau mus rau qhov kawg ntawm cov hlua LED. Pub cov xov hlau txawm tias lub qhov, thiab lo cov laug cam ua ke

Yog tias koj tsis muaj kev nyab xeeb txog koj lub neej, qhwv ob sab ntawm cov laug cam ua ke rau 2x4s. Kuv tsis tau

Yog tias cov xov hlau tau thab plaub koj, txhuam lawv nrog qhov dav dav ntawm daim kab xev thiab kua nplaum.

Kauj Ruam 3: Kauj Ruam 3: Swag Lawv Hloov Cov Ntawv Teev Npe hauv Kev Tiv Thaiv Cov Tsiaj Zes ntawm Cov Xov

Ua qhov tsis txaus ntseeg, tab sis tub nkeeg, tsheb npav hauv av (txuas nrog rau hauv av Arduino)

Pinouts

Colons - Arduino 5V thiab tsheb npav hauv av

Saib daim duab kom tas.

15 Ohm resistors (8*4 = 32)

Cov tswv yim/tawm tus pin yog GND (Hauv av)

  • LAT (Latch),
  • CLK (Moos)
  • SER (Cov ntaub ntawv xov xwm)
  • 5V (Lub zog rau tus tsav tsheb IC)
  • 12V (Lub zog rau 7-ntu zaub)

Cov ntaub ntawv hluav taws xob engineering

  • TPIC - Peb Tus Ncej Hlau Clad (taw tes hloov hluav taws xob)
  • wikipedia.org/wiki/Shift_register

Qhov no yog qhov nyuaj. Saib ntawm 6C596 hloov npe rau npe cov ntawv teev npe. Nqus nws. Qhov no yuav siv ntau qhov kev sim pib nrog kev nqus lub qhov muag nrog lub hom phiaj thaum kawg ntawm lub hlwb nqus. Dai rau hauv.
