Kuv tus ntxhais muaj ob xyoos tau thov me me rau nws lub hnub yug thib peb. Nws xav tau chav ua noj me me uas hais tias Beep. 'Koj xav tau dab tsi?' yog kuv teb. 'Chav ua noj uas hais tias beep, ib yam li mommies chav ua noj!', Nws hais tias …

Yog li, qhov ntawd yog qhov kev tshoov siab (Kuv txhais tau tias 'thov') uas tau txais kuv pib ntawm txoj haujlwm no!

Tsim lub chav ua noj me me los ua si nrog tuaj yeem siv sijhawm ntau heev vim tias kuv tsis yog tus kws paub txog ntoo, yog li kuv tau pib nrog 'npaj ua' ntoo chav ua noj: Ikea Duktig. Kuv ntseeg siab heev, tias kuv tsis tuaj yeem tsim chav ua noj zoo dua rau tus nqi ntawd.

Tham txog tus nqi, qee tus yuav xav tsis thoob tias tus nqi tag nrho rau txoj haujlwm no yog dab tsi. Zoo, Ikea Duktig chav ua noj raug nqi ib puag ncig 80 Euros uas kuv nyob. Lwm qhov yuav raug nqi kwv yees li 25 txog 30 Euros, thaum koj xaj cov khoom siv los ntawm Tuam Tshoj.

Cov vis dis aus qhia tias nws ua haujlwm li cas. Thaum chav ua noj tau qhib, lub sijhawm tam sim no tau qhia. Tam sim no koj tuaj yeem teeb tsa lub sijhawm siv lub khawm xiav thiab khawm daj. Lub pob xiav ua rau lub sijhawm teem thiab khawm daj ua rau lub sijhawm poob qis. Kev nce ntxiv yog tib yam li lub qhov cub ntawm 'mommie', yog li cov nyees khawm yuav cia koj hloov ntawm 0:05, 0:10, 0:15, 0:20, 0:20, 0:25, 0:30, 0:40, 0: 50, 1:00, 1:15, 1:30, 1:45, 2:00, 2:15, 2:30, 2:45, 3:00, 3:30, 4:30, 4:30, 4:30, 5:00, 5:30, 6:00, 7:00, 8:00, 9:00 lossis 10:00 feeb: vib nas this. Yog tias koj nyiam lub sijhawm ntev dua (lossis lwm yam) lub sijhawm, tsis muaj teeb meem, tsuas yog ntxiv lub sijhawm teem sijhawm ua ntej hauv cov cai. Yog vim li cas kuv thiaj nres ntawm 10 feeb, yog tias kuv tsis xav kom sawv thaum ib tag hmo xav tsis thoob yog dab tsi beeped.:-)

Ok, tam sim no lub sijhawm tau teeb tsa, nias yooj yim ntawm lub pob ntsuab pib lub sijhawm thiab lub pob liab liab nres lub sijhawm. Koj kuj tseem tuaj yeem siv khawm liab kom nres teeb tsa lub sijhawm thiab ua kom cov duab pom lub sijhawm tam sim no dua. Thaum suav suav ntawm lub sijhawm, lub qhov cub tau zoo npog los ntawm kab sawb ntawm LEDs.

Thaum lub sijhawm teem mus txog 0:00 cov duab qhia tau tias BEEP (lossis hauv Dutch PIEP) thiab tom qab ntawd koj tuaj yeem hnov 2 luv luv thiab 1 lub suab nrov ntev dua. Tom qab ntawd, lub sijhawm tam sim no yuav tshwm rau hauv cov zaub dua.

Qee qhov kev hloov kho yuav tsum tau ua rau cov ntoo ntoo ntawm chav ua noj rau cov yam ntxwv ntxiv:

  • Kev hloov pauv rau pem hauv ntej: qhov rau 4 LED-cov nyees khawm thiab tso saib
  • Hloov pauv rau sab laug: lub qhov rau lub zog khawm
  • Hloov pauv rau hauv qab phaj: qhov rau DC nkaus

Hloov mus rau pem hauv ntej

Thov rub tawm PDF-file hauv qab no (nco ntsoov tias koj yuav muaj khawm sib txawv me me thiab/lossis tso saib, tab sis koj tuaj yeem yooj yim tsim cov qauv zoo sib xws siv cov cuab yeej kos duab). Nws muaj cov qauv uas kuv tau siv los ua lub qhov nyob rau hauv ntej. Kuv yooj yim kaw tus qauv rau ntoo thiab xub drilled lub qhov me me nyob hauv nruab nrab ntawm txhua lub pob. Cov xub ib txwm taw tes rau ntawm lub ces kaum sab saud. Tom qab qhov kev siv me me me, Kuv hloov mus rau qhov loj me ntsis, qhov 16 hli xyaum me ntsis kom raug dua (vim qhov no yog txoj kab uas hla ntawm cov nyees khawm LED uas kuv tau xaiv rau txoj haujlwm no).

Txog rau lub qhov tso saib, Kuv xub drilled ntau qhov hauv qhov tsaus ntuj ntawm tus qauv. Thaj chaw tsaus hauv tus qauv muaj qhov ntev ntawm cov zaub nws tus kheej. Txhawm rau ua kom tiav lub qhov tso tawm, kuv siv lub cuab yeej me me tig, cov ntawv thiab rab riam ntse. Cov cheeb tsam me ntsis me ntsis muaj qhov ntxhib ntawm PCB uas txuas nrog cov zaub. Yog tias koj yuav nce cov zaub hauv qhov no, koj yuav pom tias ntoo yog tuab heev. Thaum kuv tso cov zaub, Kuv tsis nyiam qhov zoo li no thiab siv lub router los ua ntoo tsawg dua. Koj yuav tsum ntsuas qhov siab ntawm cov zaub koj tus kheej, vim tias koj yuav tsis muaj cov zaub zoo ib yam.

Hloov mus rau sab laug vaj huam sib luag

Lub hwj huam khawm nyob ntawm lub vaj huam sib luag ntoo ntawm sab laug ntawm chav ua noj. Rau qhov no, lub qhov tau raug laum nyob rau sab laug sab laug ntawm lub vaj huam sib luag. Nco ntsoov tias qhov chaw zoo tshaj plaws rau lub pob no yog nyob rau sab saum toj, zoo li yuav pom tseeb thaum nyeem cov lus sib dhos. Sab hauv lub txee yuav tau muab lub vaj huam sib luag tshiab tso rau sab saum toj (txhawm rau lo LED kab rau thiab tiv thaiv cov khoom siv hluav taws xob), yog li nws zoo dua kom muaj lub pob saum toj no lub vaj huam sib luag.

Nyob sab hauv ntawm lub vaj huam sib luag sab laug, Kuv tau siv lub router me me los tsim lub qhov rau lub zog hluav taws xob kom khiav hla.

Hloov mus rau hauv qab phaj

Rau DC jack, Kuv tau xaiv hauv qab los teeb nws rau. Raws li lub vaj huam sib luag hauv qab yog tuab heev, xub xyaum lub qhov uas tsuas yog loj txaus rau qhov txuas tiag (hlau ib feem ntawm qhov txuas). Tom qab ntawd laum -los ntawm sab hauv qab up- lub qhov loj dua (ntawm chav kawm tsis tiav los ntawm lub vaj huam sib luag hauv qab!), Raws li qhov txuas muaj cov yas yas uas yuav nyob hauv txoj kev lwm yam. DC-vaj huam sib luag mount tuaj yeem muab lo rau ntawm qhov chaw.

Cov khoom siv hluav taws xob rau txoj haujlwm no yog qhov yooj yim heev. Tag nrho txoj haujlwm khiav ntawm lub zog 12V me me. Lub latching khawm, cia koj hloov lub hwj chim rau thiab tawm. Arduino Nano thiab lwm qhov chaw tau khiav ntawm 5V, yog li qhov hluav taws xob tau hloov pauv siv DC-DC phaw hloov pauv. Nco ntsoov tias LED-strip kuv siv, xav tau 12V.

Arduino Nano nyob nruab nrab thiab txuas nrog rau:

  • 5V fais fab los ntawm DC-DC phaw
  • 4 khawm (Pib, Nres, Ntxiv thiab Rho Tawm)
  • SWB 32231
  • TM1637-tso saib
  • Buzzer
  • LED-sawb

Plaub lub nyees khawm tau yooj yim txuas nrog cov tswv yim digital thiab rau GND. Hauv txoj cai, rub sab hauv tau teeb tsa. DS3231 txuas nrog I2C. Rau Arduino Nano, SDA txuas nrog A4 thiab SCL txuas nrog A5. Cov zaub yuav tsum nyob ib sab ntawm 5V thiab GND, ob lub chaw nres nkoj digital.

Rau lub suab nrov thiab LED-sawb, Kuv tau siv lub perfboard me me. Ob qho tib si txuas nrog cov khoom siv digital ntawm Arduino. LED sawb txuas nrog ntawm 1 kOhm resistor thiab transistor. Txhawm rau kom yooj yim thaum sib dhos, Kuv txuas lub LED-sawb nrog tus txuas. Thaum kuv ua tiav tag nrho cov laug, Kuv xav tias kuv siv ntau txuas. Nrog cov txuas, koj tuaj yeem sim sim txhua qhov sib cais thiab yog tias ib feem ua tsis tiav vim li cas los xij, nws yooj yim dua los hloov.

Txhawm rau tiv thaiv ib qho kev luv luv luv luv, Kuv tau siv cov raj me me. Thiab ua ntej nqaim cov hlab, xyuas seb txhua qhov ua haujlwm!:-)

Tam sim no nws yog lub sijhawm los sib sau ua chav ua noj. Ua ntej tshaj, ntxig tag nrho cov nyees khawm hauv qhov tsim. Raws li kuv siv cov nyees khawm LED, txhua tus muaj xim sib txawv, kuv xaiv cov lus txib hauv qab no (ntawm sab laug mus rau sab xis): xiav, daj, ntsuab, thiab liab

Kev ua haujlwm ntawm cov nyees khawm yuav yog (tib qho kev txiav txim): nce lub sijhawm, txo lub sijhawm, pib lub sijhawm ntsuas qhov cub, thiab nres.

Tom qab ntawd, ntxiv lub hwj huam khawm, DC nkaus thiab tso saib. Nco ntsoov tias kuv lub TM1637 zaub muaj qhov txuas ntawm sab xub ntiag. Qhov txuas no tau raug tshem tawm (desoldering). Kuv tau tso cov khoom kuv tau hais los saum no thiab tom qab ntawd ua raws li Ikea phau ntawv qhia thiab kom txog thaum lub txee saum toj yuav tsum tau teeb ntawm chav ua noj. Nco ntsoov tias cov khoom siv sib txuas thaum lub chav ua noj twb tau ua me ntsis lawm, ua kom yooj yim dua, vim tias koj tsis tas yuav tuav cov khoom siv.

Raws li qhov no yuav yog txoj haujlwm menyuam yaus yuav ua si nrog, nws yog lub tswv yim zoo tiag tiag los tiv thaiv txhua yam khoom siv hluav taws xob. Nws tsis yog tiv thaiv menyuam yaus, nws yog kev tiv thaiv cov khoom siv hluav taws xob los ntawm cov kev tshawb nrhiav me me …:-) Cov hlua LED kuj tseem tuaj yeem ua rau nws zoo ib yam. Lub qhov me me txaus los tso cov xov hlau hla. Cias txiav tawm ib feem ntawm 5 mm MDF qhov ntev x mm. Cov ntoo ntoo seem tuaj yeem siv los tuav lub phaj hauv qhov chaw. Tsis txhob thaiv ib qho ua ntej qhov drilled qhov nyob rau sab panels, raws li cov qhov yuav tsum tau rau assembling chav ua noj.

Thaum chav ua noj tiav lawm, Kuv tsim lub logo zoo hauv cov yas dub thiab txiav qee cov yas pob tshab liab (los ntawm lub tswb qub) hauv qhov tseeb qhov ntev rau cov zaub.

Rau kev tsim lub Arduino, Kuv siv Arduino IDE. Qhov kev zov me nyuam yuav tsum muaj 4 tus qauv los teeb tsa. Cov no yog:

  • DS1307RTC (hauv kev tswj cov tsev qiv ntawv hauv Arduino IDE)
  • Sijhawm (https://github.com/PaulStoffregen/Time)
  • TM1637Display (https://github.com/avishorp/TM1637)
  • Hlau (builtin)

Txoj cai muaj ntau cov lus hauv kab lus rau kev qhia meej ntxiv, vim kuv tsis xav tias tus lej nws tus kheej yuav piav qhia tus kheej rau txhua tus (suav nrog kuv tus kheej tom qab ob peb hlis). Dab tsi cov lus pom tsis muaj yog kev saib xyuas tag nrho nws ua haujlwm li cas. Yog li ntawm no kuv yuav muab cov lus qhia nrawm ntawm qhov program.

Tom qab teeb tsa txheej txheem, txoj haujlwm tuaj yeem yog ib ntawm plaub lub xeev, raws li Arduino yog:

  • Qhia lub sijhawm ntawm cov zaub (lub xeev qub)
  • Teem caij timer
  • Qhia lub timer uas suav mus rau 00:00
  • Beeping

Hauv txheej txheem txheej txheem txheej txheem, cov hauv qab no yuav tshwm sim txhua lub voj:

  • Txheeb cov nyees khawm seb puas tau raug nias thiab ua raws

    Piv txwv li, nce tus timer nrog ib qib, nres lub sijhawm thiab hloov lub xeev kom pom lub sijhawm, thiab lwm yam

  • Txheeb xyuas seb puas yuav tsum tau ua dab tsi raws li lub xeev tam sim no

    Piv txwv, txo lub sijhawm raws li qhov thib ob tau dhau mus, lossis qhia lub sijhawm tshiab, txij li lub sijhawm tau hloov pauv
