Kauj Ruam 3: ESP32-CAM Wiring Modes

ESP32-CAM module sib xyaw ESP32-S Module, lub koob yees duab OV2640, daim npav microSD daim npav, LED nyem, thiab ntau I/O pins. ESP32-CAM tso cai rau koj teeb tsa cov vis dis aus wireless, muab lub vev xaib sib cuam tshuam rau server, sib txuas lub koob yees duab wireless rau hauv koj lub tsev siv tshuab, ua lub ntsej muag pom/paub, thiab ntau ntxiv.

Txhim Kho Lub Koob Yees Duab: Lub koob yees duab txuas ntawm ESP32 yog lub qhov dawb nrog lub ntsej muag xim av lossis xim dub nyob ntawm ntug. Qhov tsaus nti hinges nqis deb ntawm PCB mus rau qhov dawb ntawm qhov txuas. Thaum qhib, qhov txuas txuas tau ntxig rau hauv lub qhov dawb nrog lub lens tig tawm. Thaum kawg, qhov tsaus nti tau nyem rov qab rau hauv qhov txuas. Nco ntsoov tias lub lens muaj daim ntawv npog tiv thaiv tshaj li tuaj yeem tev tawm ua ntej siv.

PROGRAMMING MODE

Txhawm rau ua haujlwm ESP32-CAM, xaim FT232RL USB Serial Adapter raws li qhia. Nco ntsoov teeb lub hwj chim jumper ntawm FT232RL USB Serial Adapter rau 3.3V. Qhov luv ntawm IO0 thiab GND pins tau siv los tso ESP32 rau hauv hom haujlwm. Cov hlau no tuaj yeem raug tshem tawm kom tso cai rau ESP32 kom khau raj rau hauv hom kev ua tiav.

WEBCAM MODE

Ib zaug ua haujlwm, ESP32-CAM tsuas yog xav kom muaj 5V thiab GND txuas nrog. USB Lub Hwj Huam Siv Hluav Taws Xob tuaj yeem siv lossis lwm yam 5V cov khoom siv muaj peev xwm muab tam sim no txaus.

KEV SIB THAM SIB THAM

Txhawm rau khiav ESP32-CAM thaum tseem txuas nrog USB (piv txwv li, txhawm rau saib cov ntawv tso tawm saib) tsuas yog txuas ob qho ntawm cov qauv raws li pom ntawm no tib lub sijhawm, tab sis tom qab ntawd tshem IO0 hauv av thaum kev ua haujlwm tiav. Qhov no yuav tso cai rau ESP32 kom ua tiav thiab siv USB/txuas txuas nrog thaum tseem muab tam sim no txaus los ntawm 5V tus pin kom muaj zog ESP32. Yog tsis muaj 5V muab, 3.3V cov zis ntawm FT232RL yuav tsis muaj zog ESP32 thiab "brownout" tsis ua tiav cov lus nrog tshwm sim.

Kauj Ruam 4: ESP32-CAM Webcam Streaming Server

Kauj Ruam 5: Cov Khoom Siv Hluav Taws Xob

Lub capacitor ceramic yog lub tsub nqi muaj txiaj ntsig qhov twg cov khoom siv ceramic ua raws li dielectric. Nws yog tsim los ntawm ob lossis ntau txheej sib pauv ntawm cov nplais thiab txheej hlau ua raws li cov hluav taws xob. Qhov muaj pes tsawg leeg ntawm cov khoom siv ceramic piav qhia tus cwj pwm hluav taws xob ntawm lub capacitor. (Wikipedia)

Lub hauv paus Circuit Court muaj kev sib tham muaj txiaj ntsig suav nrog kev ntsuas lub peev xwm suav nrog qee qhov piv txwv ntawm kev ntsuas lub peev xwm siv Arduino kho vajtse thiab cov haujlwm. Ntshe nqes mus rau ntu nqe lus "CAPACITANCE METER FOR 470 UF TO 18 PF CAPACITORS" rau qhov kev qhia ua piv txwv uas tuaj yeem siv nrog hom ntawm cov khoom siv hluav taws xob hauv cov Khoom Siv Ceramic Capacitor. Thaum cov duab piav qhia txog Arduino UNO, kev siv Arduino Nano tuaj yeem siv tau ib yam. Tom qab teeb tsa Arduino IDE rau program Arduino Nano, yooj yim muab tshuaj txhuam rau hauv "THE CODE FOR SERIAL MONITOR OUTPUT" los ntawm nplooj ntawv txuas mus rau hauv IDE thiab suav sau/rub tawm cov ntawv tso rau hauv Nano.

Yog xav paub ntxiv txog kev teeb tsa thiab teeb tsa program Arduino Nano, saib hauv phau ntawv qhia online rau HackerBoxes Starter Rhiav.

Kauj Ruam 6: Cov Khoom Siv WOPR Cov Ntawv Cim

Cov cim WOPR no muaj kaum yim LEDs nrog rau xim-caij tsheb kauj vab tswj tau los ntawm analog capacitor-timed oscillators. Cov piv txwv ua ntej HackerBox tau siv hom kev sib piv zoo li no rau cov teeb pom kev zoo sib xws LED. Tus qauv tsim ua rau peb nco tias microcontrollers, ntau npaum li peb hlub lawv, tsis tas yuav tsum tau txais cov txiaj ntsig nthuav. Lub rooj sibtham ua tiav ntawm lub rooj sibtham yuav raug hnav raws li lub ntsej muag ntsais muag LED.

Cov Ntsiab Lus:

• Kev cai WOPR Luam Circuit Board
• Ob CR2032 Npib Cell Clips
• Rau Liab 3mm LEDs
• Rau Txiv Kab ntxwv 3mm LEDs
• Rau Ntsuab 3mm LEDs
• Peb 9014 NPN Transistors
• Peb 22uF Capacitors
• Peb 1K ohm Resistors (xim av-dub-liab)
• Peb 10K ohm Resistors (xim av-dub-txiv kab ntxwv)
• Swb Hloov
• Ob Txoj Kev Sib Nrauj

Tus qauv tsim muaj peb qhov sib txawv oscillators los tswj LED xim-caij tsheb kauj vab. Txhua ntawm 10K resistors thiab 22uF capacitors tsim ib qho RC oscillator uas ib txwm thawb cov cuam tshuam cuam tshuam rau. Peb lub RC oscillators tau muab tso rau hauv cov saw kom lawv caij tsheb kauj vab tawm ntawm theem uas ua rau qhov ntsais muag pom tshwm nyob ib puag ncig ntawm lub rooj tsavxwm. Thaum lub transistor yog "ntawm" tam sim no dhau los ntawm nws lub txhab nyiaj ntawm 6 LEDs thiab lawv 1K tam sim no txwv kev tiv thaiv ua rau lub txhab nyiaj ntawm 6 LEDs ntsais muag.

Qhov piv txwv no suav nrog kev piav qhia zoo ntawm qhov kev xav sib piv oscillator siv ib qib (ib qho oscillator thiab ib qho transistor).

Kauj Ruam 7: Cov Khoom Siv WOPR Cov Ntawv Cim

YUAV TSUM MUAJ LUS QHUAB QHIA TXOG QHOV TSEEB QHIA QHOV TSEEB: Cov cim npe zoo tshaj plaws thaum sib sau ua ke nrog cov khoom sib dhos dhau ntawm "sab xub ntiag" ntawm PCB qhov chaw ua haujlwm ntawm WOPR tau nthuav tawm. Txawm li cas los xij, cov ntsiab lus piav qhia nyob ntawm sab nraub qaum thiab cov no hais txog kev qhia kom raug ntawm cov khoom. Qhov no tuaj yeem cuam tshuam tshwj xeeb txog kev xav txog TO-92 transistors, uas yuav tsum tau muab tso los ntawm sab xub ntiag ntawm PCB nrog cov tiaj tiaj tig mus rau sab saud, uas yog tig los ntawm qhov xav tau yog tias tso los ntawm sab nraum qab ntawm PCB. TO-92 transistors kuj tseem tuaj yeem tso nrog lub tiaj tiaj tiv thaiv PCB pem hauv ntej raws li qhia hauv qhov piv txwv.

Nco ntsoov tias muaj ob qhov sib txawv qhov tseem ceeb ntawm resistors. Lawv tsis hloov pauv tau. Resistors tsis polarized. Tej zaum lawv yuav muab tso rau hauv ob qho tib si.

Nco ntsoov tias muaj peb "txhab nyiaj" ntawm LEDs D1-D6, D7-D12, thiab D13-D18. Txhua lub txhab nyiaj yuav tsum yog ib qho xim txhawm rau sib npaug qhov thauj khoom tam sim no thiab tseem rau qhov ua kom pom kev zoo. Piv txwv li, LEDs D1-D6 tuaj yeem yog (R) ED, D7-D12 txhua (G) REEN, thiab D13-D18 txhua (O) RANGE.

Cov capacitors yog polarized. Nco tseg qhov "+" ua ntawm PCB silkscreen. Lub cim "-" cim (thiab tus lej luv) ntawm lub capacitor yuav tsum tau muab tso rau hauv lwm qhov.

Cov LEDs tseem muaj qhov sib txawv. Nco tseg lub tiaj tiaj ntawm LED pom ntawm PCB silkscreen. Tus pin luv (cathode lossis cov hlau tsis zoo) ntawm LED yuav tsum nyob hauv lub qhov ze rau "sab tiaj" ntawm LED silkscreen.

Tag nrho tin tag nrho peb daim ntaub rau txhua qhov ntawm cov npib cell clips nrog cov laug. Txawm hais tias tsis muaj dab tsi los pauv mus rau hauv nruab nrab cov pawm, tinning pab tsim lub ncoo kom ntseeg tau tias muaj kev sib cuag tau zoo rau cov xov tooj ntawm tes.

Tom qab siv cov laug, ua haujlwm hloov pauv ob peb zaug kom tshem tawm cov kev sib cuag ntawm cov khib nyiab lossis oxidation.

Saib xyuas kom tsis txhob luv ob daim npib ntawm tes sib dhos ua ke thaum daim npav WOPR tau hnav.

Kauj Ruam 8: Micro Servo Pan-Tilt Assembly

Lub Rooj Sib Tham Yias-Tilt muaj ob lub micro servos, plaub lub tshuab yas yas ua pwm, thiab ntau yam kho vajtse. Lub rooj sib txoos tuaj yeem yuav los ntawm Adafruit qhov twg koj tseem tuaj yeem pom cov lus qhia zoo qhia txog kev sib dhos ua haujlwm li cas.

Arduino Servo Library tuaj yeem siv los tswj ib qho ntawm micro servos rau yias lub rooj sib txoos nyob ib puag ncig nws lub hauv paus thiab lwm lub micro servo kom qaij lub rooj sib txoos nce thiab nqis. Cov Lus Qhia no muab cov piv txwv ntxaws ntxaws rau muab ob lub servos siv Arduino code.

Pan-Tilt Assembly tuaj yeem siv los teeb tsa cov lus qhia, lasers, teeb, koob yees duab, lossis tsuas yog hais txog dab tsi. Raws li ib txwm, cia peb pom qhov koj tuaj nrog!

Ib qho kev sib tw nthuav, yog tias koj tab tom ua rau nws, yog ntxiv ob qhov kev tswj swb (yias thiab qaij) rau lub vev xaib sib tham ntawm "CameraWebCamera" piv txwv uas thawb txoj haujlwm tsis mus rau ESP32-CAM firmware uas ua rau teev ob qhov kev pabcuam tso lub webcam thaum tso tawm.
