Txais tos rau Yantrah cov lus qhia!
Peb ntawm Yantrah tsom mus rau kev kawm ntawm tes, peb qhia 3D CAD tsim qauv, ua haujlwm, STEAM thiab neeg hlau.
Nov yog qhov yooj yim arduino raws li 3d luam ntawv moos nrog flashing LED los qhia teev, feeb thiab vib nas this dhau los. Peb tsim thiab cim lub moos tag nrho hauv TINKERCAD.
TINKERCAD yog qhov yooj yim heev web-based CAD software uas tso cai rau koj los tsim qauv 3D thiab tseem muaj qhov tshwj xeeb hauv Circuit Court uas tso cai rau koj ua tus lej thiab sim ua cov kab hluav taws xob. Ua raws cov lus qhia hauv qab no kom ua rau koj tus kheej!
Peb tau muab koj nrog. STL cov ntaub ntawv rau 3D luam ntawv, coding rau arduino programming thiab ob peb cov yeeb yaj kiab ntawm qee cov txheej txheem. Txaus siab rau!
Kauj Ruam 1: Cheeb Tsam / Qhov Chaw
- 3D Luam qhov chaw (Txuas hauv qhov kev piav qhia)
- 36x LED teeb (3 xim 12x LED ntawm txhua)
- 3x arduino nano 3x 100 Ω (ohm) resistor
-
PCB pawg thawj coj saib
- Multicore kab
- Soldering hlau thiab xaim
- Kub kua nplaum phom
- 12 V lub qhov (socket)
- 12 V Adapter
- 6x PCB poj niam txuas qhov txuas nrog 15 tus pin
Kauj Ruam 2: 3D Luam Qhov Chaw
Peb tau muab koj ob daim ntawv. STL rau txoj haujlwm no. Thawj yog lub phaj ntsej muag ntawm lub moos thiab qhov thib ob yog PCB lub hauv paus phaj phaj. Peb pom zoo cov chaw teeb tsa hauv qab no:
Moos phaj:
- Cov ntaub ntawv: -20%
- Kev daws teeb meem:- 0.2 hli
- Raft:- Tsis yog
- Kev them nyiaj yug:- Tsis yog
PCB pawg thawj coj saib phaj:
- Cov ntaub ntawv: -20%
- Kev daws teeb meem:- 0.2 hli

- Kev them nyiaj yug:- Yog
Kauj Ruam 3: Teeb Lub Teeb LED
Siv koj lub ntsej muag 3D luam tawm lub ntsej muag, sib sau koj lub LED rau hauv txhua qhov. Muaj peb txheej ntawm LED's thiab txhua txheej sawv cev rau hauv qab no:
Txheej 1 = Txheej sab = RED = Thib Ob
Txheej 2 = Nruab nrab txheej = GREEN = feeb
Txheej 3 = Sab hauv txheej = Xiav = Teev
Ib zaug, tag nrho cov LED tau muab tso rau ntawm lub ntsej muag lub ntsej muag, peb yuav tsum txuas txhua tus ncej tsis zoo ntawm txhua lub teeb ci LED los ntawm ib txheej mus rau ib txoj hlua hlau los ntawm ntau lub xov tooj cable siv hlau txuas (txiav tawm ib qho xaim ntxiv). Rov ua cov txheej txheem no rau txhua txheej ntawm LED's. Nco tseg, qhov ntev kawg ntawm LED yog tus ncej zoo thiab luv dua yog tus ncej tsis zoo.
Peb tau siv rab phom kub kub txhawm rau txhawm rau txhawm rau txhawm rau xoob qhov xaus.
Kauj Ruam 4: PCB Pawg Rooj Sib Tham
Siv lub rooj tsav xwm PCB thiab txiav nws rau hauv 75 x 70mm.
Txuas txhua tus poj niam PCB txuas rau PCB pawg thawj coj thiab tom qab ntawd muab cov no pov rau lawv kom ruaj ntseg. Cov no yuav tsum tau ua kom deb txaus kom cov arduino nano tuaj yeem txuas nrog lawv, nrog qhov sib txawv ntawm txhua pawg thawj coj ntawm arduino.
Nqa cov PCB pawg thawj coj thiab muab qhov no tso rau hauv 3D luam tawm PCB pawg thawj coj saib phaj. Tam sim no tso lub ntsej muag ntawm lub moos rau hauv qhov zawj ntawm PCB pawg phaj.
Kauj Ruam 5: PCB Circuit Assembly
Txhua txheej LED xav tau txuas nrog rau pawg thawj coj saib raws li hauv qab no:
12 teev sawv ntxov - D2
1 teev - D3
2 teev - D4
3h5d ua
4 teev - D6
5 teev sawv ntxov - D7
6 teev tsaus ntuj - D8
7 teev - D9
8 teev sawv ntxov -D10
9 teev sawv ntxov - D11
10 teev sawv ntxov - D12
11 teev sawv ntxov - A1
Nco ntsoov tias txhua txheej txuas nrog cov laug cam hauv qab no:
Txheej 1 = Txheej sab nraud = Thib ob = arduino 1 (sab laug feem ntau)
Txheej 2 = Nruab nrab txheej = feeb = arduino 2 (nruab nrab)
Txheej 3 = Sab hauv txheej = Teev = arduino 3 (txoj cai tshaj)
Txuas lub hwj huam txuas mus rau PCB pawg thawj coj saib.
Kauj ruam 6: Nws yog Lub Sijhawm Coding
Peb tau ua tiav txhua qhov coding rau qhov no siv thaiv coding hauv Tinkercad. Tsis xav tau coding keeb kwm yav dhau rau qhov no. Txhawm rau ua tej yam yooj yim rau koj, peb tau muab koj cov ntaub ntawv nrog cov coding xav tau rau txoj haujlwm no.
Luam tag nrho cov cai code peb tau muab rau hauv software arduino tom qab ntawd mus rau hauv cov cuab yeej> pawg thawj coj> Arduino nano Tom qab ntawd mus rau Txheej Txheem> ATmega328P. Select qhov chaw nres nkoj koj tau txuas nrog arduino rau thiab xa cov cai
Nco ntsoov tias koj xa tus lej thib ob ntawm arduino rau ib pawg arduino, feeb rau thib ob arduino, thiab teev sijhawm rau thib peb arduino.
Kauj ruam 7: Lub sijhawm yog dab tsi?
Txuas lub xov tooj mus rau lub qhov (socket) ntawm ntse 11:59 teev sawv ntxov tam sim no koj lub moos ua haujlwm zoo kawg nkaus! Nov yog qhov koj yuav pom:
Txheej 1 = Txheej sab nrauv = Thib ob = hloov txoj haujlwm txhua 5 vib nas this
Txheej 2 = Nruab nrab txheej = feeb = hloov txoj haujlwm txhua 5 feeb
Txheej 3 = Txheej sab hauv = Teev Sijhawm - hloov txoj haujlwm txhua 1 teev
(Raws li peb tau siv yooj yim thaiv coding hauv qhov piv txwv no peb raug txwv los ntawm thaum peb tuaj yeem teeb tsa lub moos)
