Kuv ib txwm xav ua qee qhov diy teeb teeb rau kuv lub tsheb kauj vab.

Cov lus qhia no qhia tag nrho cov kauj ruam uas kuv tau hla hauv kev tsim thiab tsim txoj haujlwm no.

Kauj Ruam 1: Nws Ua Haujlwm Li Cas:

Nws ua haujlwm nrog kev pab ntawm ob lub Arduino NANO cov laug cam, uas peb muaj programmed Atmel ATmega328 microcontroller. Ntawm qhov tsim tawm, peb siv MOSFET transistor los tsav lub teeb pem hauv ntej LED, rau lub teeb pom kev peb siv WS2812 LED cov kab hluav taws xob, uas yog los ntawm Arduino NANO. Peb siv lub laub khawm (uas tuav lawv txoj haujlwm) kom qhib lub teeb taws.

Kauj Ruam 2: Cia Pib, Qhov Chaw thiab Cov Cuab Yeej:

Cov ntaub ntawv:

• 2 x Tus tswj hluav taws xob LM317
• 3 x 10Ω resistor
• 1 x 47Ω resistor

• 2 x LED sawb hom WS2812 (14LEDs)
• 2 x LED sawb hom WS2812 (27LEDs)

• 1x PCB phaj

• 4 x lub dav hlau rau Arduino (saib rau tus pin txuas)
• 8 x Cov tswv yim / cov zis tawm (2pin)
• 4 x Cov tswv yim / cov zis tawm (3pin)

Tag nrho cov nyiaj = 52 feem

Cov Cuab Yeej:

• Phom phom thiab cov laug
• Hlau txiav
• Koob qhov ntswg pliers
• Laum thiab laum cov ntsiab lus
• Tes los yog lub zog pom
• Teb Tool
• Ntawv xeb
• Digital multimeter
• yuag dua
• hmoov hmoov
• txhuam
• lauj kaub yas muaj zog
• Hlau daim txhuam cev
• Tsom iav kev nyab xeeb:)

Kauj Ruam 3: Tsim PCB nrog Computer:

Txhawm rau tsim lub voj voog uas tau teeb tsa, koj tuaj yeem xaiv ntawm tes-kos thiab khoos phis tawj tsim. Ua ntej peb pib nrog txhua hom, peb yuav tsum muaj tag nrho cov khoom (cov ntsiab lus) ntawm lub rooj, vim tias nws yog qhov tsim nyog rau kev tsim khoom ntawm txhua tus tib neeg thiab ntau yam ntawm cov khoom siv (pins). Qhov no yog qhov zoo rau peb kom ua kom pom kev zoo thiab tsis muaj cov neeg nyob hauv ib puag ncig, vim tias yog tias koj yuav tsis muaj cov ntsiab lus yav dhau los ntawm lub rooj, nws tuaj yeem tom qab kos duab thaum tsim cov khoom dhau los lossis txawm tias yuav tsis muaj chaw txaus los khov kho ntsia hauv Circuit Court.

Cov khoom lag luam yuav raug tsim los ntawm kev pab los ntawm lub khoos phis tawj EAGLE (Yooj Yim Siv Tau Yooj Yim Duab Duab). Qhov kev zov me nyuam tso cai rau peb kos lub phiaj xwm phiaj xwm, thiab tom qab ntawd siv nws los kos cov phaj phaj thiab kev sib txuas. Thaum koj tau ua tiav cov txheej txheem teeb tsa thiab kev sib txuas ntawm lawv peb xav tau ua ntej luam ntawv sib txuas ntawm ib daim ntawv, teeb tsa hauv qhov program Daim iav ua haujlwm, txwv tsis pub lub Circuit Court pom los ntawm noog kev xav. Thaum nias ntawm daim ntawv teev npe ua nrog tus pas ntsuas maj mam txuas uas peb muaj hauv lub khoos phis tawj thaum kos duab sib txuas yog 1/10 nti (2, 54mm).

Qhov program no yog pub dawb thiab tuaj yeem rub tawm los ntawm qhov txuas no:

www.cadsoftusa.com/download-eagle/

Kuv tau ua kuv tus kheej PCB board hauv computer program EAGLE, yog tias koj xav siv kuv tus PCB tsim kuv tau tshaj tawm kuv cov ntaub ntawv rau siv hauv program EAGLE.

Kauj Ruam 4: Npaj PCB:

Kev npaj cov phaj: Peb tau npaj rau kev tsim cov phiajcim hluav taws xob, rau kev tsim cov phaj tau siv uas tau siv rau hauv daim ntawv ntawm lub network uas yog 1/10 nti, thiab muaj ib sab ntawm cov tooj liab Islands tuaj. Ua ntej, peb txiav ntawm qhov loj me uas tsim nyog, saib xyuas qhov kev txiav mus rau thaj tsam loj dua li cov nplaim ntawm qhov txuas. Kom muaj tsawg kawg ib sab hom tooj liab islets dawb paug. Tom qab ntawd, ua kom huv ntawm cov tooj liab tooj liab nrog daim txhuam cev hlau txhawm rau txhawm rau txhuam hauv ib qho ntev (rov qab-rov qab) thiab tsis muaj kev txav mus los. Txoj haujlwm no yog kom tau tooj liab huv los ntawm cov av los ntawm cov av sab saud uas tau sib sau ua ke. Qhia meej saum npoo ntawm tooj liab yuav tsum tau ci. Cov npoo ntse tau sib npaug.

Qhov ntev ntawm Circuit Court:

Ntev: 31 hauv qhov sib nrug ntawm 1 / 10inch Network (7, 9cm)

Dav: 21 nyob rau hauv spacing ntawm 1 / 10inch Network (5, 3cm)

Kauj Ruam 5: Tshooj Tshooj:

Tom qab ntawv txiav cov phaj thiab daim ntawv uas cov kev sib txuas thiab cov khoom siv hluav taws xob thiab pib los ntawm cov khoom siv txuas thiab rub cov kab txuas rau cov tooj liab. tin.

Kauj Ruam 6: Pov Thawj thiab Tiv Thaiv Kua:

Kev Pom Zoo: Tom qab ntawd los txog theem uas qhov kev coj ua tau tshuaj xyuas kev sib txuas thiab ua tau luv luv Circuit Court thiab qhov ua tau tsis tuaj yeem txuas. Thaum peb pom tias txhua qhov kev sib txuas raug thiab peb tsis muaj qhov yuam kev mus rau qhov kev tiv thaiv kev sib txuas txuas txuas thiab qis dua ntawm Circuit Court.

Cov kua tiv thaiv:

Qhov no yog ua tiav ntawm lub lauj kaub yas uas muaj zog (los ntawm cov kua nplaum khoob rau cov thawv ntoo txiav hauv nruab nrab thiab muab lub khob) thiab nchuav cov hmoov sib xyaw rosin thiab sib tov nrog txhuam kom ntev kom cov plua plav tawg tag, peb tau txais cov kua daj. Yog tias koj nchuav cov kua rau hauv lub khob yas mos dua, tom qab 1 feeb yuav noj nws los hauv qab, vim nws xyaum noj yam khoom vim tias nws muaj xeb. Thaum peb muaj txhuam txhuam sab hauv qab ntawm lub voj voog, tawm cov txheej kom qhuav, yog li peb txuas txuas muab kev tiv thaiv tiv thaiv oxidation. Cov txheej txheej tsis muaj feem cuam tshuam thaum siv cov laug, yog li koj tseem tuaj yeem kho dab tsi.

Kauj Ruam 7: Cov Lus Qhia Tshwj Xeeb thiab Kev Sib Txuas:

Cov lus qhia tshwj xeeb (U, I, P):

U = 12 V DC

Kuv (teeb pom kev + lub teeb pem hauv ntej) = 0, 85A

Kuv (teeb pom kev +pem hauv ntej siab thiab qis teeb) = 1, 27A

Kuv (teeb lub teeb + pem hauv ntej teeb nqaj + tig teeb) = 1A

P (teeb lub teeb + pem hauv ntej teeb pom kev zoo) = 10, 2W

P (teeb pom kev + teeb pem hauv ntej teeb + tig teeb) = 12W

Kauj Ruam 8: Programing Microcontrollers:

Koj tuaj yeem rub tawm Arduino IDE dawb los ntawm:

www.arduino.cc/en/main/software

Kauj Ruam 9: Ua Lub Qhov Ncauj Qhov Ncauj

Lub qhov cua nkag tau tsim los ua kom txias dua cov transistors vim yog lub teeb ci pem hauv ntej. Nws muaj cov yas ramp, uas tiv thaiv nag los ntawm kev nkag mus. Peb siv lub kiv cua me me txhawm rau txhawm rau huab cua nkag mus rau hauv lub tsev, cov yas thaiv tau siv los tiv thaiv huab cua kom ncaj mus rau qhov cua nkag mus.

Kauj Ruam 10: Txoj Kev Npaj

Kauj Ruam 11: Muab Txhua Yam Ua Ke

Kuv kuj tseem ntxiv IR RGB LED sawb tswj, nws yog nyob ntawm yeem.

Kauj Ruam 12: Yees Duab Ua Haujlwm:

Kuv vam tias koj nyiam ua raws kuv nrog rau Cov Lus Qhia no! Ua tsaug rau koj nyeem!
