Tej zaum koj paub tias xov tooj cua tsis tuaj yeem xa suab, tab sis koj puas paub tias lub teeb pom kev tuaj yeem ua qhov qub? Siv cov qauv tsim hluav taws xob yooj yim heev thiab qee qhov feem ntau muaj, peb tuaj yeem tsim cov cuab yeej yooj yim uas tso cai rau peb xa cov nkauj tsis siv neeg los ntawm teeb LED!
Kauj Ruam 1: Thawj Yam Ua Ntej: Circuit
Daim duab saum toj no yog tus qauv rau lub Circuit Court uas peb yuav tsim sai sai no. Daim ntawv ceeb toom tias nws yooj yim heev; tsuas yog ib nrab kaum ob los yog li cov khoom xav tau tiag tiag los tsim cov cuab yeej no.
Kauj Ruam 2: Daim Ntawv Teev Npe
Cov khoom tsim nyog tuaj yeem yuav tau rau txhua qhov chaw nyob ib puag ncig ntawm $ 15 txog $ 50. Lawv yog raws li hauv qab no:
1. High-Brightness Dawb LEDs. Koj yuav xav kom muaj tsawg kawg 2 ntawm lawv. Lub zog siab dua lawv yog, zoo dua! (Muab lawv tau ntsuas rau 3 - 3.5 volts)
2. Ib qho diode. Koj tsis xav tau hom tshwj xeeb twg; Kuv hle qhov no tawm ntawm rab phom choj kho qhov muag.
3. (Tsis teb los tau) 10 ohm resistor. Yog tias koj cov LEDs yog hom tam sim no thiab koj muaj ob peb ntawm lawv, tej zaum koj yuav zoo yog tsis muaj tus tiv thaiv. Tab sis yog tias koj tsuas muaj ob peb thiab/lossis lawv ib txwm muaj qis-amperage LEDs, xyuas kom tseeb tias koj tau txais qhov tiv thaiv uas nyob nruab nrab ntawm 10 txog 100 ohms. Yuav tsum tau tiv thaiv siab dua rau qhov qij tam sim no.
4. Breadboard / PCB board. Qhov no tsuas yog kom muaj lub thav duab uas tsim lub Circuit Court.
5. MP3 Player thiab suab cable

7. Ib lub hnub ci vaj huam sib luag. Feem ntau, koj yuav tau txais txiaj ntsig zoo dua nrog cov vaj huam sib luag siab dua. Qhov pom hauv daim duab no tau ntsuas rau 6 volts, txawm hais tias kuv muaj qhov ntsuas loj dua rau 12 (thiab nws ua haujlwm zoo dua me ntsis).
8. 6V teeb roj teeb. Sim siv qis dua lossis siab dua voltage yuav tsis ua haujlwm. Kuv mam piav qhia vim li cas tom qab.
8. Txo cov xov tooj tooj liab. Ntau yam khoom siv, yuav tsum txuas nrog lawv!
Kauj Ruam 3: Tsim Lub Vaj Huam Sib Luag Teeb
Qhov tseem ceeb tshaj plaws ntawm txoj haujlwm no yog lub teeb pom kev zoo. Nws yog lub plawv (thiab tus neeg siv MP3 yog tus ntsuj plig) uas qhov seem ntawm "tus xa tawm" tau tsim.
Txij li thaum peb tab tom ua haujlwm nrog 6-volt qhov peev txheej thiab siv 3.3-volt LEDs, peb yuav xav tau pib los ntawm xaim cov LEDs hauv kab ntawm 2. Thaum koj tau txuas ob peb khub ntawm LEDs, hloov pauv lawv mus rau 6.6. -volt qhov muag teev, tom qab ntawv koj tuaj yeem teeb ntau ntawm cov khub no ua ke raws li koj xav tau. Feem ntau, txawm li cas los xij, kuv xav hais tias 5 lossis 6 khub ua ke (10-12 tus kheej teeb) muaj txaus. Peb tsis tau sim tsav cov no kom ci ntsa iab; qhov xwm txheej ntawm Circuit yuav tsis tso cai rau lawv kom ci ntau dua li tej zaum tsib lossis kaum feem pua ntawm lawv cov peev txheej ntsuas.
Thaum koj tau ua tiav koj cov teeb pom kev zoo, txuas nws mus rau lub roj teeb txhawm rau ntsuas nws tawm (nyiam dua nrog lub me me tiv thaiv, tshwj xeeb tshaj yog tias koj tau txais qis dua LEDs).
Kauj ruam 4: MP3 Player Interface
Teeb lub teeb bar ib sab, qhov kev txiav txim tom ntej ntawm kev lag luam yog txhawm rau txheeb xyuas txoj hauv kev txuas peb cov neeg siv MP3 rau kev sib dhos. Qhov no tuaj yeem ua tiav siv qhov ua ntej 3.5mm lub mloog pob ntseg nkaus, lossis (kom pheej yig dua thiab nrawm dua) ob peb daim hlau tooj liab.
Tam sim ntawd, thaum koj tshuaj xyuas qhov kawg ntawm koj lub xov tooj cua, koj yuav pom tias nws tau muab faib ua peb ntu. Peb lub hom phiaj yog txhawm rau txuas ob ntawm peb ntu no rau hauv Circuit. Txhawm rau ua tiav qhov no, nqa ib daim me me ntawm cov tooj liab liab liab liab - tej zaum 4 lossis 5 ntiv tes ntev - thiab qhwv nws nruj nreem ncig cov lus qhia sab nraud. Koj tuaj yeem ntswj cov hlau ua ke tom qab koj tau qhwv nws peb lossis plaub zaug nyob ib ncig ntawm lub ntsaws, ua kom ruaj ntseg ntxiv. Ua kom ntseeg tau tias koj tso tsawg kawg ob lossis peb ntiv tes ntawm tooj liab kom txaus kom koj tuaj yeem txuas qhov no mus rau hauv Circuit Court tom qab.
Tom ntej no, nrhiav lwm daim ntawm cov tooj liab liab liab, thiab ntswj nws nruj nyob ib ncig ntawm ntu sab hauv (ib feem ntawm lub tsho sab nraud sab nraud). Yog tias txhua yam mus tau zoo, thaum koj tau nyab xeeb ob qho kev sib txuas, koj yuav tsum muaj tooj liab xaim nyob ib ncig ntawm ntu 1 thiab ntu 3 ntawm lub tsho, nrog ntu ntu nruab nrab yog sab laug tsis cuam tshuam los ntawm xaim. Txij ntawm no mus, yog tias koj xav tau, koj tuaj yeem qhwv daim kab xev hluav taws xob nyob ib puag ncig nws kom ruaj ntseg cov xov hlau ruaj khov nyob hauv qhov chaw.
Thaum koj ua tiav nrog cov theem no, koj lub rooj sib txoos yuav tsum zoo ib yam li daim duab saum toj no.
Kauj Ruam 5: Txuas lub Circuit Court ua ke
Ntseeg nws lossis tsis ntseeg, tam sim no peb yuav luag tiav nrog lub hauv paus tseem ceeb!
Txhua yam uas tau ua yog txuas tus tiv thaiv (yog tias koj muaj ib qho) thiab cov diode rau lub rooj sib txoos. Ua qhov diode yog qhov tseem ceeb tshaj ntawm ob, cia pib nrog nws.
Thaum koj saib cov diode, koj yuav pom tias nws muaj cov qhab nyob ntawm ib kawg ntawm nws. Cov qhab no qhia cov kev taw qhia uas tam sim no yuav hla mus. Txhawm rau ua kom tiav Circuit Court, nco ntsoov tias koj lub diode's band yog "taw qhia" mus rau qhov tsis zoo ntawm Circuit Court. Qhov no nyuaj rau piav qhia, thiab nws yog qhov pom tau zoo dua los ntawm kev saib ntawm daim duab kos duab rov qab thaum pib ntawm Cov Lus Qhia no.
Xijpeem …
Ib sab ntawm lub suab tso yuav txuas nrog tus tiv thaiv (lossis tsis muaj tus tiv thaiv), uas yuav tig mus txuas nrog lub davhlau ya nyob twg zoo ntawm lub roj teeb. Qhov sib txawv ntawm qhov txuas ntawm lub jack yuav koom nrog rau lub diode (sab uas tsis yog banded).
Txuas mus rau qhov kawg ntawm cov diode yuav yog lub davhlau ya nyob twg zoo ntawm koj lub vaj huam sib luag LED. Qhov tsis zoo kawg ntawm LED vaj huam sib luag yog tom qab ntawd txuas rau lub roj teeb tsis zoo, thiab voila! Tam sim no lub Circuit tiav. Txhua yam uas yuav tsum tau ua yog txhawm rau txuas qhov kawg ntawm kab lus txuas rau hauv MP3 player thiab rub koj cov nkauj nyiam. Tab sis ua ntej koj ua li ntawd …
Kauj Ruam 6: Tus "Reciever"
Txhawm rau kom tuaj yeem mloog koj cov nkauj nyiam, koj yuav xav tau ib khub ntawm lub mloog pob ntseg thiab lub hnub ci vaj huam sib luag. Dab tsi peb yuav tsum ua kom tiav rau cov kauj ruam no yog qhov tseem ceeb tib yam li peb tau ua dab tsi los txuas lub MP3 player rau kis kab mob.
Pib los ntawm txuas cov xaim tooj liab mus rau qhov kawg ntawm koj lub mloog pob ntseg txuas, ua kom ntseeg tau tias tso tawm ob lossis peb ntiv tes dawb ntawm xaim. Txuas lwm cov xaim mus rau ntu ntu peb ntawm koj lub xov tooj, sib tawm tsam thawj qhov txuas uas koj tau ua. Txhawm rau txhim kho koj cov kev sib txuas, qhwv qee daim kab xev hluav taws xob nyob ib ncig ntawm lub jack, kom ntseeg tau tias cov xov hlau tsis dhau hla. Qhov no tsuas yog tso cai rau koj hnov lub suab hauv ib lub pob ntseg, tab sis qhov zoo ntawm lub suab ntawd yuav tsum nyob ze qhov koj xav tau yog tias koj ntsaws koj lub mloog pob ntseg ncaj qha rau hauv MP3 player.
Yog li, nrog koj zoo siab! Koj nyuam qhuav ua qhov pom-teeb-rau-suab-hloov pauv. Ib qho txaus nyiam los sim ntawm lub sijhawm no yog tuav koj lub hnub ci vaj huam sib luag nyob ib sab ntawm lub teeb pom kev zoo hauv koj lub tsev. Yog tias koj muaj lub teeb ci LED, koj yuav hnov lub suab ntsiag to los ntawm koj lub mloog pob ntseg, vim tias lub teeb tau ci ntsa iab thiab tawm 60 zaug ib pliag vim yog lub zog siv hluav taws xob ntau heev! Yog tias koj tseem tsis tau nyob ib puag ncig kom yuav ib qho LED teeb, tseem qhib TV thiab tuav koj lub vaj huam sib luag ze ntawm lub vijtsam. Npaj kom hnov ntau qhov tawg, nrov nrov, thiab tawg thaum lub hnub ci vaj huam sib luag khaws ntawm lub teeb ntws los ntawm tus saib.
Kauj Ruam 7: Mloog hauv
Tam sim no uas peb tau ua tiav ob ntu rau txoj haujlwm no, txhua yam uas tau ua yog kom tua nws thiab mloog. Txuas lub Circuit Court mus rau lub roj teeb, ntsaws thiab qhib koj lub MP3 player, thiab tuav lub hnub ci vaj huam sib luag hauv ob peb ntiv tes ntawm LEDs. Yog tias txhua yam mus tau zoo, koj yuav hnov koj cov nkauj nyiam ua si hla 'lub teeb yoj!' Ib qho ntxiv, nco ntsoov saib lub teeb thaum nrawm dua lossis nrawm ntawm cov nkauj, vim tias lawv tuaj yeem nyem thiab tsaus me ntsis nrog kev sib txawv ntawm lub suab.
Kauj Ruam 8: Nws Ua Haujlwm Li Cas
Qhov tseem ceeb, qhov Circuit no ua rau peb 'encode' cov ntaub ntawv suab mus rau lub teeb nthwv dej.
Rau kev teeb tsa raug, cov LEDs yuav raug siv tawm ntawm lub roj teeb. Txij li tam sim no muab los ntawm roj teeb yog DC (ncaj qha tam sim no), yuav tsis muaj qhov sib txawv kiag li hauv lub teeb ntawm LEDs. Tab sis yog tias peb muab lub suab tso rau nruab nrab ntawm lub teeb thiab lub roj teeb, txhua yam hloov pauv.
Thaum lub suab txuas txuas nrog lub MP3 player, MP3 hla qhov hluav taws xob me me tam sim no los ntawm nws. Feem ntau, qhov tam sim no yuav siv los txhawb koj lub mloog pob ntseg, txij li lub mloog pob ntseg me ntsis ntau dua li cov tshuab hluav taws xob zoo tshaj uas siv hluav taws xob tsawg heev los khiav. Tab sis hauv txoj haujlwm no, peb tab tom yuam lub teeb liab me me no los hloov "cuam tshuam" cov hluav taws xob ntws mus rau LEDs.
Tam sim no, qhov txias tshaj plaws kom nco ntsoov (thiab kev tshawb fawb me ntsis uas ua rau txoj haujlwm no ua tau) yog qhov kev cuam tshuam hauv hluav taws xob ua rau cov LEDs 'nyem.' Ntxiv mus, qhov flashing tshwm sim hauv tus qauv zoo ib yam li kev cuam tshuam. Thiab txij li qhov kev hu ua cuam tshuam yog, qhov tseeb, lub teeb liab nqa cov nkauj, uas txhais tau tias lub teeb tam sim no 'xa tawm' cov ntaub ntawv uas yog MP3 player tab tom tawm.
Nyob rau hauv kev zam zoo ib yam li lub xov tooj cua xov tooj cua tau txais kev tshaj tawm, peb tom qab ntawd siv lub hnub ci vaj huam sib luag los hloov lub teeb ci teeb ci rov qab rau hauv hluav taws xob, uas lub mloog pob ntseg tuaj yeem hloov mus rau lub zog suab. Ka-boom tau! Tam sim no koj tab tom mloog nkauj.
Kauj Ruam 9: Qee Cov Lus Cim Random
Txog "Tshuav Lub Hwj Chim"
Nyuam qhuav pib hauv Cov Lus Qhia no, Kuv tau hais tias peb yuav xav tau lub zog hluav taws xob kom raws nraim 6 volts. Tab sis vim li cas qhov no? Qhov tseem ceeb, nws yog vim peb xav tau 'sib npaug' lub zog hauv Circuit nrog teeb liab los ntawm MP3 player. Los ntawm kev tso lub zog ntau dhau los ntawm LEDs, ib tus yuav xaus kev tsav tsheb hla lub Circuit Court, yog li poob dej tawm lub teeb liab thiab ua suab nrov.
Kuv tau sim qhov kev hloov pauv ntawm txoj haujlwm no ntau lub lis piam dhau los uas kuv tau siv lub vaj huam sib luag LED nrog 12 volt fais fab mov. Tab sis txij li qhov hluav taws xob tau zoo tshaj li qhov LEDs tau ntsuas tus txheej txheem rau, nws tau tso tag nrho qhov tam sim no ntxiv mus ncaj nraim mus rau lub qhov txuas txuas, cuam tshuam lub teeb liab thiab ua suab paj nruag tsis mloog. Nws yog qhov ua tau los ntsuas qhov tsim qauv no, tab sis koj ib txwm xav kom ntseeg tau tias koj lub vaj huam sib luag LED qhov ntsuas hluav taws xob siab dua me ntsis ntawm koj lub zog tso tawm. Hauv peb qhov xwm txheej, peb tab tom ua hluav taws xob 3.3 volt LEDs (6.6 volts thaum ob leeg tso ua ke) los ntawm roj teeb uas tuaj yeem thawb tawm - feem ntau - 6.5 volts. Yog li, tag nrho cov hluav taws xob ntau tshaj tawm los ntawm LEDs, tawm hauv lub teeb liab kom huv thiab huv.
