Ntse Teeb (TCfD) - Zaj sawv + Suab Nkauj Visualizer: 7 Kauj Ruam (nrog Duab)

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Txoj haujlwm no ua tiav rau chav Kawm Technology rau Kev Tsim Qauv ntawm TUDelft

Qhov khoom kawg yog ESP-32 lub hauv paus LED teeb thiab txuas nrog tus neeg rau zaub mov. Rau cov qauv, lub teeb muaj ob txoj haujlwm; zaj sawv zaj uas ua rau muaj xim zoo nkauj hloov pauv mus rau nws ib puag ncig thiab lub suab thib ob pom qhov twg LED pixel "seev cev" raws qib suab. Lub kaw lus txuas nrog wifi thiab tus neeg siv tuaj yeem xaiv qhov txiaj ntsig uas lawv xav tau los ntawm lub teeb ntawm WIFI.

Tus nqi pheej yig ESP-32 microchip muab rau peb nrog cov txheej txheem muaj zog, inbuilt hall sensor, ntsuas kub, kov sensor thiab tseem muaj peev xwm wifi thiab bluetooth. Nrog rau qhov no, Whilst tsuas yog ob qhov cuam tshuam raug xaiv rau txoj haujlwm no, Qhov cuam tshuam ntawm lub teeb "ntse" no tsis muaj qhov txwv. Nws yuav siv los qhia huab cua rau tus neeg siv, lossis qhov kub ntawm chav, lub teeb nws tus kheej tuaj yeem ua lub tswb tswb lossis nws tuaj yeem muab lub hnub ci ci ci ci nyob ib sab ntawm koj lub txaj ua piv txwv txog hnub tuaj rau qhov kev paub zoo.

Kauj Ruam 1: Cov Khoom Xav Tau

Arduino esp32

Suab sensor

Plaub txoj kev Bi-Directional Logic Level converter

Neopixel coj 2m 60 coj/m

Jumper xov hlau

Micro USB cable nrog adapter

Kev sib txuas hauv Is Taws Nem

Kauj Ruam 2: Daim duab Circuit Court

Ib daim duab qhia chaw tau kos thiab Circuit tau ua raws li tau hais hauv

daim duab hauv qab no.

Kauj Ruam 3: Arduino Code

Ntawm no, ua ntej pom qhov chaws tau ua. Tom qab ntawd, ob qho piv txwv code

; "Neoplxel RGBW starndtest"; thiab "yooj yimWebServerWifi" tau hloov kho thiab sib koom ua ke hauv cov lej pom kev. Txawm hais tias txoj cai tseem muaj kab laum nyob rau qee lub sijhawm (kev coj ua lub teeb pom kev zoo rau lub sijhawm). Kev rov ua dua ntawm cov cai (ib zaug peb tau txais sijhawm txaus) yuav raug hloov kho.

Kauj Ruam 4: 3d Luam Ntawv Pib Lub Teeb

Ib qho qauv 3D ntawm lub teeb puag tau ntsuas, tsim thiab luam tawm nrog qhov loj txaus kom haum rau txhua qhov khoom siv hluav taws xob sab hauv lub hauv paus.

Kauj Ruam 5: Coj Txuas

Led tau cua nyob rau hauv cov ntawv los xij thiab txuas nrog siv daim kab xev ob tog, lub qhov tau raug laum rau hauv qab kom dhau cov xaim hla

Kauj Ruam 6: Teeb Lub Teeb

Lub thawv ntim khoom tau tsim los ntawm kev nrhiav lub raj mis pob tshab nrog qhov dav sib xws li lub hauv paus teeb thiab qhov siab raws li cov ntawv txuas LED. Qhov no twb tau npog nrog cov ntawv tuab kom nthuav dav zoo dua ntawm lub teeb. Xwb, nws muaj peev xwm siv cov iav khov los yog cov yas yas zoo li lub thaiv teeb.

Kauj ruam 7: Teeb tsa

Txhua yam tau glued ua ke thiab sib sau ua ke. Thiab lub teeb tau npaj rau qee qhov kev sim!.
