Koj yog lub luag haujlwm tag nrho rau koj cov kev ua, thiab ua rau lawv ntawm koj tus kheej txoj kev pheej hmoo!

Nrog qhov ntawd, cia peb pib!

Kauj Ruam 1: Sau Qhov Chaw

Rau qhov kev qhia no koj yuav xav tau cov hauv qab no:

• DOIT ESP32 pawg thawj coj loj
• Micro USB cable (txhawm rau upload cov cai thiab lub zog ESP32 dev board)
• Reflowduino32 "hnab ev khoom" module rau ESP32 dev board
• Toaster qhov cub (nyeem cov lus hauv qab no kom paub meej ntxiv)
• K-hom thermocouple (suav nrog Reflowduino32)
• Sidekick relay module (los nrog lub luag haujlwm hnyav C13 fais fab cable)
• 2x txiv neej-txiv neej Dupont jumper xov hlau (txhawm rau txuas Reflowduino32 mus rau qhov txuas txuas)
• Lub taub hau me me taub hau ntswj taub hau (rau zawm cov ntsia hlau txuas)

Cov khoom xyaw tseem ceeb ntawm no yog ESP32 dev board, Reflowduino32, thiab Sidekick relay module, thiab tau kawg, lub toaster cub nws tus kheej. Kuv yuav piav qhia luv luv txhua yam hauv qab no:

ESP32 Dev Board + Reflowduino32

Tam sim no Reflowduino32 tau tsim los ntsaws rau hauv ESP32 dev pawg thawj coj saib yog li pawg thawj coj saib dev yuav tsum muaj lub taub hau sib nrug kom raug thiab pinouts txhawm rau ua haujlwm no. Kuv tau tsim Reflowduino32 hnab ev khoom tshwj xeeb rau "DOIT" ESP32 dev board txij li kuv pom tias qhov no tau npaj muaj hauv online thiab zoo li tau siv dav. Txawm li cas los xij, yog tias koj pom lwm ESP32 dev pawg thawj coj uas muaj tus pinouts zoo ib yam thiab tus pin sib nrug ces thov qhia rau kuv paub vim tias yuav tsum ua haujlwm ib yam nkaus!

Toaster Cub

Nws yuav tsum yog qhov pom tseeb qhov no ua dab tsi hauv cov phiaj xwm loj ntawm yam khoom tab sis nws yuav tsis pom tseeb li yam thiab hom twg los xaiv. Tus kheej kuv tau sim qhov pheej yig Walmart toaster qhov cub uas tau ntsuas ntawm 1100W thiab yog qhov zoo heev. Kuv xav tias txhua yam siab dua 1000W yuav tsum tsim nyog rau kev nyiam ua haujlwm tab sis muaj qee qhov kev txiav txim siab. Yam tseem ceeb los saib hauv lub tshuab ci ci yog lub wattage (> 1000W dua), qhov loj me (pes tsawg tus laug cam koj xav kom haum hauv nws?), Kev teeb tsa lub tais (nws puas muaj qhov zoo, tais tais uas koj tuaj yeem siv los tso rau? PCB nyob ntawm?) thiab seb nws puas yog lub qhov cub ci ci ci (tej zaum koj yuav ua zaub mov ntau dua ntawm cov laug cam thiab xav kom muaj ntau qhov kub thiab txias faib thoob plaws hauv qhov cub?). Tag nrho cov xwm txheej no tiag tiag nyob ntawm koj tus kheej daim ntawv thov tab sis rau kuv qhov pheej yig, cov khoom siv Walmart toaster ua haujlwm tau zoo xwb.:)

Koj yuav nug, ua li cas txog cov phaj kub? Hauv kuv lub tswv yim kuv yuav tsum tshem tawm cov phaj kub vim tias lawv zoo li muaj cua sov ntau. Qhov no txhais li cas yog tias lawv yuav ua kom sov thiab ua kom sov sov txawm tias zoo tom qab koj tua nws. Qhov no ua rau nws tsis tuaj yeem kwv yees tau zoo rau kev tswj qhov kub vim tias qhov kub tuaj yeem hla dhau los ntawm qhov ntau thiab tuaj yeem ua rau muaj kev puas tsuaj rau ib puag ncig ntawm koj cov laug cam. Yeej siv lub phaj kub yuav swb lub hom phiaj ntawm kev siv tus tswj xyuas rov qab ua ntej.

Relay Module

Txhawm rau tswj qhov ntsuas kub peb yuav tsum tau tswj lub toaster rau thiab tawm raws li qhov ntsuas kub peb nyeem los ntawm lub thermocouple. Txawm li cas los xij, lub qhov cub ci ci yog cov khoom siv AC thiab muaj lub zog zoo (nrog 120VAC toasters feem ntau teeb duab txog 8-10A) yog li peb yuav tsum paub tseeb tias peb tuaj yeem tsav nws kom raug yam tsis muaj kev thauj khoom ntau dhau. Lwm qhov kev xav yog kev tswj qhov hluav taws xob ntawm kev xa tawm. Feem ntau hobbyist relays (Arduino-tau tshaj) muaj peev xwm hloov pauv siab tam sim no tau ntsuas rau 5V cov tswv yim tab sis hauv qhov kev qhia no peb tab tom cuam tshuam nrog ESP32 uas ua haujlwm ntawm 3.3V. Qhov no txhais tau tias qhov nruab nrab Joe relay module yuav tsis ua haujlwm rau peb. Txawm li cas los xij, hauv qhov xwm txheej koj xav siv qhov hloov pauv sib txawv sib txawv Kuv tau tsim qhov tshwj xeeb uas koj tuaj yeem hloov qhov kev tswj hwm qhov hluav taws xob los ntawm lub neej qub 3.3V mus rau "VIN" qhov hluav taws xob ntawm ESP32 dev board, uas yog lub neej ntawd yog ~ 5V thaum siv los ntawm USB. Txawm li cas los xij, koj tuaj yeem ua haujlwm sab nrauv-lub zog nws nrog qee yam siab dua 5V, hais tias 9V, thiab tom qab ntawd qhov kev tswj hwm qhov hluav taws xob yuav yog 9V. Uas tau hais tias, koj yuav tsis ib txwm xav tau dab tsi siab dua 5V.

Qhov no yog ib nrab vim li cas kuv thiaj tsim Sidekick relay module, lub zog muaj zog-lub xeev muaj peev xwm hloov pauv tau ib qho kev cai lij choj 120VAC cov cuab yeej thiab tsis muaj ib qho nyem nrov nrov (zoo-xeev) zoo li kev tso tawm ib txwm muaj! Nws kuj muaj kev nyab xeeb thiab yooj yim txuas thiab kom yooj yim txuas cov cuab yeej, microcontroller, thiab lub zog loj (AC phab ntsa qhov hluav taws xob) yog li qhov no yog qhov kuv yuav siv ntawm no. Qhov txias yog koj tsis tas yuav qhib lub toaster qhov cub kom tswj tau nws!

Kauj ruam 2: Teeb Kho Vajtse

Tswj Lub Tswv Yim

Tiag tiag, lub tswv yim yog qhov ncaj ncaj: Thaum kawg peb lub hom phiaj yog tswj hwm qhov kub hauv lub qhov cub toaster. Txhawm rau ua qhov no peb yuav tsum tswj lub qhov cub toaster ntawm thiab tawm ib ntus nrog cov qauv hloov pauv, zoo ib yam rau PWM tab sis qhov tseeb qeeb ntawm nws (txhua lub sijhawm qhov rai yog 2s, yog li nws tuaj yeem nyob rau 1.5s thiab tawm rau 0.5s). Txhawm rau tsav lub relay peb yuav tsum tau muab nws qhov hluav taws xob kom raug ntawm tus lej tswj kev xa xov (logic HIGH = ON, LOW = OFF). Hauv peb qhov xwm txheej peb yooj yim txuas ob qhov kev xa tawm tswj kev nkag mus rau Reflowduino32's relay ntsia hlau davhlau ya nyob twg. Yog vim li cas peb tsis txuas ncaj qha rau ESP32 cov pins digital mus rau kev xa tawm yog vim tias kev xa tawm thim qhov zoo me ntsis tam sim no (piv rau IO pins tuaj yeem ua haujlwm tau zoo) thiab peb tsis xav kom ntau dua ESP32. Reflowduino32 suav nrog MOSFET qhov hloov pauv qis thiab tuaj yeem tswj tau ntau dua 200mA ntawm tam sim no, yog li ua rau ESP32 tus pin los ntawm kev puas tsuaj.

Yeej tsuas yog ua raws "Reflowduino32 + Sidekick Control" daim duab thaiv kab lus saum toj no thiab koj yuav tsum zoo mus!

Cov Toaster Cub Cub

Ntseeg nws lossis tsis ntseeg, qhov no yog ntu tseem ceeb hauv qhov kev qhia no! Yog tias koj tsis mob siab rau ntawm no koj yuav xav tsis thoob vim li cas koj lub khob cij tsis tig rau txawm tias koj ua raws txhua yam ntxiv. Vim li cas? Zoo, txhawm rau peb tswj lub toaster sab nrauv (ntawm nws lub hwj huam qaum) yam tsis tau qhib nws, peb yuav tsum ua lub toaster zoo li nws ib txwm nyob yog tias peb yuav ntsaws ncaj qha rau hauv phab ntsa. Vim tias lub toaster tau hloov pauv los ntawm kev xa rov qab peb tuaj yeem tswj tau thaum lub tshuab toaster raug kaw, tab sis yog tias lub tshuab ci ci qee zaum qhib lossis qee zaum tawm thaum qhov kev xa tawm tau ua haujlwm ces peb tau teeb tsa peb tus kheej rau qhov ua tsis tiav. Qhov no yog vim li cas thawj qhov peb yuav tsum tau ua yog teeb lub pob qhov rooj ntawm lub toaster. Feem ntau cov tshuab ci ci yuav muaj peb lub pob qhov rooj: ib qho rau qhov kub, ib qho rau qhov chaw ci, thiab lwm qhov rau lub sijhawm. Yam koj yuav tsum tau ua yog cov hauv qab no:

• Tshaj tawm qhov ntsuas kub (peb tsis xav kom peb cov txheej txheem rov ua dua kom nres ib nrab txoj kev!)
• Teem qhov kev xaiv ua zaub mov rau "Ci" lossis ib yam dab tsi ua rau tag nrho cov cua sov filaments tig rau sab hauv!
• Max tawm lub timer lossis, hauv qhov xwm txheej ntawm kuv lub toaster, tig lub pob qhov rooj timer rau "Nyob twj ywm" kom nws yeej tsis tig!

Tom qab ua qhov no, ntsaws lub toaster lub hwj huam qaum rau hauv qhov hluav taws xob thiab koj yuav tsum hnov thiab pom nws qhib. Bingo! Yog tias hauv qhov xwm txheej koj ntshai tias koj yuav yuam kev qhov yuam kev yuam kev, xav kom sov cov kua nplaum rau hauv qhov chaw kom lawv tsis txhob txav mus!

Tam sim no tias peb lub toaster ib txwm nyob thaum lub zog, peb tuaj yeem hloov nws los yog tua nrog kev xa rov qab nrog kev thaj yeeb nyab xeeb ntawm lub siab tias nws yuav qhib tiag tiag thaum qhov kev sib txuas tau qhib.
