Kauj Ruam 2: Luam Circuit Board

Thaum kuv pib nrog lub dashbutton yam no, Kuv tsim pcb version ib yam yam tsis muaj qhov tshwj xeeb - tsuas yog txuas ob peb ntu nrog cov cim hluav taws xob. Kuv yuav tsis pom zoo cov ntawv no vim tias nws yog thawj daim ntawv sau tseg thiab nws tsis tau tsim kho zoo ib yam. Nov yog cov ntsiab lus me me ntawm tag nrho peb qhov kev hloov pauv:

Version 1 yog kuv thawj daim ntawv kawg uas muaj qee yam los ua kom zoo dua. Tej zaum kuv yuav hloov kho yav tom ntej tab sis nws tau ua haujlwm lawm. PCB muaj cov txheej sab nrauv ntawm 24x32mm. Nws tau siv los ntawm lub roj teeb LiPo me me thiab tsuas muaj lub zog tswj hluav taws xob rau lub zog ESP8285-M3. Lub roj teeb txuas nrog qee daim kab xev ob npaug rau hauv qab ntawm lub dashbutton.

Version 2 suav nrog lwm qhov zoo ntawm PCB. Nws yog puag ncig nrog txoj kab uas hla ntawm 30 hli thiab suav nrog lub dav hlau hauv av hla ob feem peb ntawm thaj chaw. Lwm qhov thib peb yog lub kav hlau txais xov ntawm lub microcontroller thiab yuav tsum tsis txhob sib tshooj nrog ib qho ntawm cov kab los yog cov cim hauv av kom txo kev cuam tshuam. Schematic yog tib yam li version ib. Thiab ib yam li version ib nws yog raws li ESP8285-M3.

Version 3 muaj lwm qhov zoo ib yam thiab. Qhov sib txawv tseem ceeb yog tias nws tau siv los ntawm tus qauv LIR2450 roj teeb uas tuaj yeem hloov pauv tau yooj yim yog tias nws tau txais khoob thiab yog li ntawd PCB yuav tsum loj dua me ntsis dua li lwm qhov. Ib qho ntxiv, nws suav nrog WS2812b rgb (w) coj los qhia rau ntawm yam sib txawv. Tsis tas li ntawd thiab hauv qhov sib piv rau lwm ob qhov nws tau ua raws ESP8266-07S.

Yog li tsuas yog xaiv cov ntawv los ntawm cov ntawv txuas thiab tso koj xaj ntawm koj lub tuam txhab PCB uas koj nyiam.

Kuv twv yuav raug hu qhia qhov thib ob, vim tias nws yog qhov kev txhim kho tshaj plaws ntawm txhua qhov thiab qhov loj me me tsuas yog 30mm yog qhov yooj yim heev hauv kuv lub tswv yim. Thaum koj xav kom muaj cov yam ntxwv ntxiv hauv qhov me me, tom qab ntawv hais txog version peb, tab sis cov ntawv no tseem ua haujlwm txuas ntxiv thiab tej zaum yuav tsum tau ua kom zoo dua hauv qee yam …

Kauj Ruam 3: Ua kom tiav koj li PCB

Yog tias koj tuav koj lub PCB hauv koj txhais tes, nws yog lub sijhawm los muab cov khoom sib txuas rau nws. Txhawm rau ua li ntawd, koj tuaj yeem siv cov thev naus laus zis twg koj nyiam. Hauv kuv qhov xwm txheej kuv tau siv cov khoom sib xyaw nrog cov kua nplaum thiab cov tshuab rov ua dua tshiab. Rau qhov no koj yuav xav tau qee qhov muab tshuaj txhuam tso rau hauv lub koob txhaj tshuaj, lub chaw tso tshuaj txhuam rov qab (lossis qee yam zoo li rab phom cua kub) lossis lub qhov cub. Zoo li muaj nyob hauv daim vis dis aus no (rau version ob) lossis cov vis dis aus saum toj no (rau version peb), koj yuav tsum faib me ntsis ntawm cov tshuaj txhuam txhuam rau txhua smd xaim hlau ua ntej koj tso cov khoom rau nws qhov chaw muab. Hauv cov vis dis aus rau version ob nws tau qhia nrog lub tshuab ua kom tsis siv neeg ib nrab thiab tso lub ntsej muag tab sis cov khoom siv tau loj txaus los ua kom lawv ua haujlwm tau zoo ib yam li pom hauv daim vis dis aus rau qib peb.

Tom qab qhov no koj tuaj yeem muab cov PCB tso rau hauv qhov cub lossis muab tshuaj txhuam rau lawv nrog koj cov thev naus laus zis xaiv. Cov txheej txheem no tseem pom raws li lub sijhawm ncua sij hawm hauv cov vis dis aus sab saud.

Tau kawg, qhov no yuav tsum ua tau nrog cov hlau sib txuas ib yam nkaus, tab sis kuv xav tias yuav tsis yog txoj hauv kev yooj yim tshaj plaws thiab koj yuav tsum ua siab ntev.

Kauj Ruam 4: Teeb ESP

Flashing lub microcontroller ntawm lub pcb yuav tsis yog qhov yooj yim tshaj plaws. Tab sis yog li ntawd tias lub dashbutton yuav tsum yog me me li sai tau, tseem muaj tsawg dua li cov khoom siv tau. Txhawm rau nyem nws, muaj peb yam tseem ceeb uas koj yuav tsum siv.

• GPIO0 (PROG rau version peb) xaim hluav taws xob jumper yuav tsum tau luv kom muab ESP hauv hom phiaj. Nco ntsoov, tias lub microcontroller yuav tsis pib li qub nrog qhov luv GPIO0/PROG xaim hlua.
• Koj yuav tsum txuas plaub daim ntaub xaim (3, 3v - gnd - rx - tx) rau sab nraud FTDI adapter. Ua li ntawd, koj tsis tas yuav siv qee cov xov hlau rau nws. Vim tias kuv tau ua raws plaub daim kab xev hauv 2, 54 mm, kab sib chaws koj tuaj yeem nqa 4-pin tus pinheader, txuas nws nrog cov hlua txuas rau FTDI adapter thiab nias nws tawm tsam cov ntaub qhwv hlau thaum rub tawm daim duab. Thiab vim tias daim duab muaj nqis tshaj txhiab lo lus, kuv tau ntxiv ib qho uas qhia txog cov txheej txheem no.
• Txoj cai tom qab tshaj tawm cov lus hauv Arduino IDE tshwm, koj yuav tsum nias lub pob pib dua ib zaug (nws yog LUB KOOB - khawm nkaus xwb ntawm lub dashbutton). Tom qab qhov no xiav coj ntawm ESP yuav tsum nyem ob peb zaug kom txog thaum nws taws tas li thaum lub bar tso rau sab hauv Arduino IDE ua tiav.

Kuv lub dashbutton tau muab tso rau hauv Apples HomeKit lub moj khaum los tswj hwm yam sib txawv hauv kuv lub tsev. Kuv yuav tsis mus rau hauv ntxaws yuav ua li cas rau nruab nws lossis nws ua haujlwm li cas vim qhov no yuav mus dhau qhov uas tau hais tseg. Yog tias koj xav ua nws ib yam nkaus koj tuaj yeem xa mus rau qhov ua haujlwm txaus ntawm KhaosT, uas ua haujlwm ntawm node.js kev siv HomeKit accessory server, uas kuv tau siv ib yam. Rau cov uas yuav siv nws kuv txuas Dashbutton_accessory.js cov ntaub ntawv.

Txawm li cas los xij nws muaj peev xwm los ua ke cov dashbuttons rau hauv lwm daim ntawv thov ntse hauv tsev, lossis ntau dua. Cov ntawv txuas nrog Arduino ua haujlwm nrog MQTT, uas yuav ua haujlwm nrog yuav luag txhua qhov kev siv tsev ntse.

Thaum koj xav pib nrog tus lej Arduino txuas nrog, tom qab ntawd yooj yim ntxiv koj li ntawv pov thawj wifi thiab MQTT tus tswv lag luam tus IP chaw nyob hauv cov kab hauv qab no:

const char* ssid = "XXX";

const char* password = "XXX"; const char* mqtt_server = "192.168.2.120";

Cov duab kos yooj yim tsa ESP los ntawm hom pw tsaug zog thaum khawm rov pib dua ib zaug. Tom qab qhov no nws yuav txuas mus rau qhov tshwj xeeb wifi network ntxiv rau MQTT broker, ua ntej nws tshaj tawm cov lus yooj yim (zoo li ib '1') rau cov ncauj lus tau piav tseg. Tom qab ntawd ESP rov qab mus rau hom pw tsaug zog. Puas yog koj lub network tsis tuaj yeem ncav cuag ESP, nws yuav rov qab mus rau hom pw tsaug zog tom qab rau vib nas this, tab sis tsis tau tshaj tawm dab tsi. Qhov no tsuas yog txhawm rau tiv thaiv lub roj teeb kom tas sai heev.

Kauj Ruam 5: Luam Vaj Tsev

Lub dashbutton yuav tsum tau ua haujlwm lawm thaum koj tau mus txog qib no. Tab sis nws yuav tsum tau txais rooj plaub me me los tiv thaiv qee qhov kev puas tsuaj rau PCB lossis rau cov khoom siv hluav taws xob. Tau kawg qhov no yog qhov muaj tswv yim ib feem ntawm Cov Lus Qhia no. Yog li, yog tias koj xav tau, koj tuaj yeem tsim koj lub tsev nyob thiab luam tawm ntawm koj lub tshuab luam ntawv 3d zoo li kuv tau ua. Koj tuaj yeem pib los ntawm kos lossis koj tuaj yeem siv kuv cov ntaub ntawv thiab ntxiv qee qhov kev hloov kho. Pom tseeb, cov tsev nyob tuaj yeem pom ntawm Thingiverse, tab sis kuv tau txuas cov ntaub ntawv ntawm no ib yam.

Cov ntaub ntawv lossis - kom raug dua - lub hau rau version 3 tseem tsis tau npaj txhij, tab sis kuv yuav hloov kho sai li sai tau.

Kauj Ruam 6: Muaj Kev Lom Zem thiab Muaj Tswv Yim

Yog li, vam tias koj tuaj yeem hloov koj lub teeb los ntawm ib lub pob nyem tam sim no!

Tsawg kawg, kuv qhov kev suav tau pom tias lub roj teeb muaj peev xwm ntawm ib qho thiab ob yuav nce mus txog 150 hnub nrog cov txiaj ntsig hauv qab no:

• Peev Xwm LiPo ntawm 105mAh
• thauj khoom tam sim no ntawm 70mA
• pw tsaug zog tam sim no ntawm 20µA
• sijhawm tshaj tawm 3 vib nas this
