Kuv nyob hauv ib lub tsev uas nws tsis yooj yim pom tias lub qhov rooj qhov rooj qhib lossis kaw. Peb muaj lub pob nyob hauv tsev, tab sis lub qhov rooj tsis pom kev. Kev xav ntawm kev tsim vaj tsev qee yam kev hloov pauv thiab lub zog hluav taws xob yog qhov tsis xav tau vim tias muaj qhov tshwm sim siab ntawm kev ua tsis tiav, nyob hauv qhov qias neeg thiab kub lossis txias ib puag ncig. Tsis tas li kuv tsis paub Arduino los ntawm ATMega328, yog li zoo nkauj wi-fi cov kev daws teeb meem tau tawm ntawm cov lus nug.

Nws tshwm sim rau kuv tias yuav tsum muaj qhov qhib/kaw qhov qhib hauv qhov qhib kom qhia chav nyob qhov twg lub qhov rooj tau teeb tsa thiab thaum twg yuav tsum nres. Hauv kuv chav Liftmaster/Craftsman nws hu ua "txwv txwv", thiab nws siv 3.7 volts DC. Tam sim no kuv muaj cov xwm txheej qhia hauv kuv lub tsev rau tus nqi ntawm ob LEDs, tus tiv thaiv thiab qee cov xaim (Qee chav Chamberlain muaj qhov hloov pauv tib yam. Cov chav nyob tshiab tau teeb tsa programmable, tab sis tej zaum tseem muaj qee yam kev txwv lub cev hloov uas koj tuaj yeem siv tau).

Raws li lub cev muaj zog tig mus rau ib txoj kev lossis lwm qhov txuas nrog lub iav tig 3 ntiv tes xov txuas uas muaj +3.7 volt hluav taws xob sib cuag, uas tom qab ntawd taug kev ib txoj kev lossis lwm qhov nyob ntawm seb txoj kev txav mus li cas, hu rau "nce" thiab "Nqes" kev sib cuag hluav taws xob ntawm qhov kawg. Qhov hluav taws xob nruab nrab ntawm qhov nruab nrab thiab qhov sib tiv kawg tuaj yeem siv los teeb LEDs. Thaum lub chaw nruab nrab hu rau thaj chaw tawm ntawm ib sab lossis lwm qhov, tus txheej txheem nres lub qhov rooj thiab ib qho LED yuav tua, tawm mus rau lwm qhov.

Ceeb toom! Qhov hack no ua haujlwm tau zoo tab sis kuv tsis muaj lub luag haujlwm rau qhov raug mob lossis puas tsuaj uas koj raug. Thov tsuas yog ua tiav ntawm koj kom paub tseeb tias koj tab tom ua dab tsi thiab ntawm koj tus kheej txoj kev pheej hmoo.

resistor hlau

Kauj Ruam 1: Txuas Cov Hluav Taws Xob

Ua ntej tshaj, tshem lub chav tsev thiab tshem lub hau. Kuv txuas 50 taw ntawm xaim mus rau nruab nrab thiab txhua qhov kev sib cuag kawg thiab txuas lawv mus rau LEDs hauv tsev.

Muaj ob peb yam los xav txog:

Yuav ua li cas txuas kuv cov xov hlau rau cov ntsuas? Kuv tsis xav txiav cov xov hlau uas twb muaj lawm, yog li kuv tau siv kuv lub qhov muag mus rau qhov twg cov xov hlau uas twb muaj lawm txuas nrog. Hauv daim duab cov xov hlau grey yog lub hauv paus kev mus ntsib, thiab cov xov hlau daj thiab xim av yog cov cim qis thiab qis. Xyuas kom koj cov xov hlau nruab nrab yoog raws thiab ntev txaus los mus rau txhua qhov kawg. Txij ntawm no mus nws tsis muaj teeb meem qhov kev sib cuag yog 'nce' lossis 'nqis' - koj tuaj yeem hloov cov coj ntawm LEDs yog tias koj xav hloov qhov LED nruab nrab nce thiab nqis. Kuv siv cov xov hlau tuab rau thawj 6 ntiv tes ua ntej yuav xaim rau cov xaim xaim xwv kom kuv tuaj yeem txuas tau yooj yim yog xav tau. Koj tuaj yeem pom qhov dav dav nruab nrab hluav taws xob tiv tauj, 'L' zoo li qhov kawg-sib cuag ntawm lawv cov hlua xov dawb, ntxiv rau lub zog uas tig tus pas nrig nruab nrab.

Kuv pom qhov hloov pauv ci ntsa iab vim tias nws yooj yim tab sis muaj zog, tuaj yeem kav 20 lossis 30 xyoo nyob rau ib puag ncig hnyav. Nws kuj tseem tuaj yeem siv tau, hloov pauv tau thiab pheej yig, tsis zoo li lub koos pij tawj tswj hwm tshiab.

Kauj Ruam 2: Txuas cov LEDs thiab Resistor

Tus nqi dab tsi rau LED resistor? Kuv ntxiv qhov xav tau tam sim no tso tus neeg tawm tsam tab sis pom tias txaus tam sim no tseem ntws los nres lub qhov rooj hauv nruab nrab txoj haujlwm. Nws coj txog 9000 ohms ntawm kev tiv thaiv ua ntej tus txheej txheem nres pom tam sim no, tab sis cov LEDs tseem pom zoo. Kuv tso lub resistor ntawm LED kawg kom nws yuav hloov pauv tau yooj yim yog tias kuv xav tau tus nqi sib txawv.

Cov xov hlau zoo li cas? Peb tab tom tham txog qhov me me ntawm qhov hluav taws xob thiab tam sim no kuv muaj peev xwm siv cov hlua nyias ntawm CAT-5 network hlau kuv tau dag ib ncig.

Kuv siv cov xim sib txawv LEDs los sawv cev rau qhov xwm txheej nce thiab nqis (koj tseem tuaj yeem siv LEDs ntawm tib xim nrog cov ntawv cim tab sis nws yuav nyuaj rau pom qhov nce los ntawm nqes los ntawm hla ib chav. Koj kuj tseem tuaj yeem siv ob xim LED nrog peb ua). Koj yuav pom tias koj yuav tsum tau siv cov rhiab/ci LEDs txij li cov resistor yog ntawm tus nqi siab. Kuv soldered nruab nrab-kev sib cuag +3.7 volt xaim mus rau tus tiv thaiv thiab tom qab ntawd mus rau ob LED zoo ob txhais ceg. Txhua qhov kawg-ntsuas xaim ces txuas rau ib qho LED tsis zoo txhais ceg.

Kauj Ruam 3: Nruab LEDs

Thaum kawg, Kuv tau teeb tsa LEDs ntawm lub vaj huam sib luag qub uas tsis tau siv dua ib sab ntawm lub pob qhib. Yog tias qhov chaw nruj, koj tuaj yeem xav muab cov tshuaj tiv thaiv ob lossis peb ntiv tes deb ntawm LEDs. Cov qhov muag teev hauv daim duab no nyuaj rau pom, tab sis lub teeb ci tuaj yeem pom thoob plaws hauv chav. Raws li kev ntxiv nyiaj ntxiv tsis muaj kev sib cuag thaum kawg raug kov raws li lub qhov rooj taug kev nce lossis nqis kom ob qho tib si LEDs yuav taws.

Kev Xaiv: Yog tias koj tsuas xav paub thaum lub qhov rooj nce (lossis qis), koj tuaj yeem siv tsuas yog ob lub xov hlau thiab ib lub LED thiab siv nruab nrab thiab tsuas yog ib qho kawg-kev sib cuag.
