Nyob zoo sawv daws! vam tias koj nyob zoo. Hauv qhov kev qhia no kuv yuav qhia kuv yuav ua li cas kuv ua qhov khoom siv kho kom haum tus phooj ywg rau ESP8266-01 tus qauv nrog kev tswj hluav taws xob kom raug thiab cov yam ntxwv uas pab kom lub teeb nyem ntawm ESP. Kuv tau ua cov qauv no tshwj xeeb kom qhib microcontrollers internet ua haujlwm siv cov qauv no, yog li kuv tsis tau tsim tus pin breakout rau GPIO pins. Cov qauv no los ua ke thaum sim ua qhov IoT project lossis hloov kho firmware ntawm ESP board. Koj tuaj yeem yooj yim zog qhov no nrog 5V yam tsis muaj kev txhawj xeeb txog kev rhuav tshem koj li ESP pawg thawj coj vim nws twb muaj tus tswj hwm qhov hluav taws xob. Cov lim dej lim dej kuj tau ntxiv txhawm rau txhawm rau tswj lub zog nkag mus rau ESP. Yog li cia peb npaj mus ua tus adapter no.
Khoom siv
- ESP8266-01 tus qauv
- Perfboard/Veroboard
- 1K, 2.2K resistors
- AMS1117 3.3v tus tswj hwm
- Txiv neej berg strip
- Poj niam berg strip
- Capacitors: 47uF thiab 0.1uF
- Qee qhov txuas xov hlau
- Soldering Iron thiab cov khoom siv
Kauj Ruam 1: Sau tag nrho Cov Yuav Tsum Muaj
Cov khoom xav tau los ua tus adapter tau hais nyob hauv cov kauj ruam dhau los.
Thaum xub thawj peb txiav cov perfboard raws li peb qhov yuav tsum tau ua thiab txiav txim siab txoj haujlwm ntawm cov khoom sib xws.
Kauj Ruam 2: Soldering Cheebtsam
Tom qab ua tiav qhov kev tso kawm ntawm cov khoom, peb thaum kawg pib txheej txheem txheej txheem. Es tsis txhob siv lub tshuab ESP ncaj qha rau ntawm lub rooj tsav khoom Kuv xub muab cov poj niam berg sawb txuas rau kom ESP tus qauv tuaj yeem raug tshem tawm yog tias xav tau. Muaj qhov tshwj xeeb no tso cai rau peb hloov ESP module raws li qhov peb xav tau thiab peb tsis txwv rau siv tsuas yog ib pawg ESP. Nws yog ntau dua ntawm kev tsim qauv. Lub lim hluav taws xob haum rau hauv qab ESP tus qauv.
Kauj Ruam 3: Ntxiv Qhov Voltage Divider Network
Vim li cas peb thiaj xav tau lub network faib hluav taws xob koj nug?
Qhov laj thawj yog tias ESP8266 tus qauv ua haujlwm ntawm 3.3 volts thiab 5 volts (uas feem ntau yog qhov ntsuas me me siv kuv cov microcontrollers zoo li Arduino) tuaj yeem ua rau IC puas tsuaj. WiFi module thiab Arduino microcontroller sib txuas lus siv cov lus sib txuas uas siv Tx thiab Rx cov ntaub ntawv kab. Tx cov ntaub ntawv kab los ntawm Arduino ua haujlwm ntawm 5 volt logic level hos ESP board yog 3.3 v system. Qhov no tuaj yeem ua rau ESP pawg thawj coj tsis zoo yog li peb siv lub network faib hluav taws xob ua los ntawm 2.2K thiab 1K resistor rau Rx tus pin ntawm ESP8266 kom coj qhov hluav taws xob qis txog 3.6 volts (uas yog me ntsis siab dua 3.3v tab sis tseem siv tau). Arduino tau yooj yim sib xws nrog 3.3v logic yog li Tx pin ntawm ESP thiab Rx tus pin ntawm Arduino tuaj yeem txuas ncaj qha.
Cov duab saum toj no qhia txog txoj haujlwm ntawm lub network faib hluav taws xob ntawm pawg tswj hwm
Kauj Ruam 4: Ua Kom tiav Cov Txheej Txheem Txheej Txheem
Tom qab muab tag nrho cov khoom sib dhos tso rau hauv qhov no yog lub rooj tsav xwm zoo li cas. Yog, ib lossis ob qhov kev sib txuas tsis tau txog qhov cim, uas yog vim kuv tau ua qee qhov yuam kev hauv txoj haujlwm tivthaiv. Kev muab cov khoom sib dhos tso rau ntawm lub qhov rooj ntoo yuav tsum tau muab tswv yim zoo ua ntej mus rau txheej txheem txheej txheem tshwj xeeb thaum lub rooj tsavxwm muaj daim ntawv me me. Txawm li cas los xij, kuv pawg thawj coj tawg tau npaj tiav thiab ua haujlwm zoo:)
Kauj Ruam 5: Daim Duab Circuit Court thiab Saib Kawg
Kuv tau txuas daim duab qhia chaw rau lub rooj sib cais no. Xav tias dawb los nthuav lub rooj tsavxwm thiab ntxiv cov pins ntxiv raws li koj daim ntawv thov. Kuv vam tias koj nyiam txoj haujlwm no! Xav tias dawb los qhia koj cov lus pom thiab cov lus nug hauv cov lus. Muaj ib hnub zoo:)
