Txoj haujlwm no piav qhia yuav ua li cas thiaj ua Arduino-based, tswj lub suab, IOT relay hloov. Qhov no yog qhov txuas uas koj tuaj yeem qhib thiab tua nyob deb siv lub app rau iOS thiab Android, ntxiv rau khi nws rau hauv IFTTT thiab tswj nws nrog koj lub suab siv Google Tsev thiab/lossis Alexa ib yam. Peb yuav npog tag nrho cov kauj ruam xav tau los tsim lub cuab yeej, txuas lub app, thiab txuas hauv ntau yam kev pabcuam IOT ib yam.

Khoom siv

• Wemos D1 Mini Lite ESP8285 (ob peb daus las ntawm Amazon)
• 5V Relay Module rau Arduino/Raspberry Pi
• 2N2222 NPN transistor
• 47K ohm resistor
• 1K ohm tiv thaiv

Kauj ruam 1: Tsim Circuit Court

Thawj kauj ruam yog xaim xov hluav taws xob. Kuv tau suav nrog cov txheej txheem thiab kab kos kab ib txwm muaj, nyob ntawm seb koj tau siv li cas. Kuv tau ua kuv thawj lub Circuit Court ntawm ib lub khob cij ua ntej thiab tom qab ntawd hloov nws mus rau PCB rau kev teeb tsa tas mus li thiab nyob hauv lub thawv 3D luam tawm qhov project.

Cov kis tau tus mob yog opto-cais H/L 5V relay, uas txhais tau hais tias ua ntej, qhov ua rau lub tshuab hluav taws xob raug cais tawm ntawm kev xa mus rau nws tus kheej, uas tshem tawm txhua qhov teeb meem muaj peev xwm nrog kev tawm tswv yim rov qab mus rau Wemos microcontroller. Muaj kev nyab xeeb zoo. Qhov thib ob, nws yog qhov hloov pauv siab/qis, uas txhais tau tias nws tuaj yeem teeb tsa tau, los ntawm kev txav cov jumper daj uas koj pom hauv cov duab, los ntawm qhov ua rau thaum lub teeb liab siab (+5V), lossis ua rau thaum lub teeb liab qis (0V). Wemos nws tus kheej xa tawm 3.3V los ntawm nws cov pins digital thiab peb tab tom siv D1 raws li peb lub hauv paus ntsiab lus, uas txhais tau tias peb yuav tsum ua kom nrov nrov me ntsis, yog li peb tau ze rau +5V cov teeb liab digital los ua rau kev xa tawm. Hloov koj tuaj yeem siv 3.3V xa tawm thiab tshem tawm cov transistor lub tshuab hluav taws xob tiv thaiv hauv Circuit Court thiab mus ncaj qha los ntawm D1 mus rau lub teeb liab tus pin ntawm kev xa tawm. Kuv tsis muaj 3.3V xa tawm, yog li peb siv ntau dua 5V kev xa tawm thiab amp Circuit.

DC+ thiab DC- ntawm qhov txuas txuas mus rau 5V thiab GND pins ntawm Wemos, uas muab qhov hluav taws xob tsim nyog los ua haujlwm txuas. Kev xa tawm tau ntsuas los ntawm cov hluav taws xob me me txhua txoj hauv kev rau kab hluav taws xob, tab sis kuv siv qhov no los tswj cov ntawv thov hluav taws xob qis. Yog tias koj siv qhov no los tswj cov kab hluav taws xob, thov xyuas kom koj paub tias koj tab tom ua dab tsi, koj tsim nyog tau txais, thiab koj ua raws li kev ceev faj uas tsim nyog. Yog tias tsis yog, tsis txhob siv qhov no los tswj cov kab hluav taws xob daim ntawv thov.

Pin D1 ntawm Wemos txuas rau 47K ohm resistor uas pub rau hauv paus ntawm NPN transistor. Tus emitter txuas rov qab rau hauv av. Tus neeg khaws khoom tau txuas nrog lub teeb liab nkag ntawm qhov txuas. Kev xa tawm tau teeb tsa kom qis qis, yog li thaum D1 muab lub teeb liab, 3.3v lub teeb liab tau nce mus txog kwv yees li 5V thiab qhib qhov qhib. Thaum D1 qis dua, lub teeb liab mus rau qhov txuas mus qis thiab qhov txuas txuas tau kaw thiab ua tiav qhov Circuit Court.

Kuv tsis nco qab thaij duab ntawm kuv lub voj voos ib ntus ntawm daim ntawv qhia zaub mov, tab sis nws zoo nkaus li zoo li daim duab Fritzing saum toj no, yog nws pab tau. Kuv suav nrog cov duab ntawm kuv qhov xwm txheej tas mus li tas li koj tuaj yeem pom tias nws tau txuas li cas, yog tias koj xav tau qee qhov kev nkag siab lossis xav tau kev pom ntawm cov khoom tshwj xeeb uas kuv siv.
