Kuv yog tus nyiam guitar thiab yog tus nyiam ua si. Feem ntau ntawm kuv cov phiaj xwm tshwm sim ib puag ncig cov khoom siv guitar. Kuv tsim kuv tus tswv amps thiab qee qhov kev ua kom muaj zog.

Yav dhau los kuv tau ua si hauv pab pawg me thiab ntseeg kuv tus kheej tias kuv tsuas xav tau lub amp nrog lub suab nrov, cov channel huv thiab cov kuab av qias neeg, thiab lub raj lub suab nrov nrov pedal los txhawb kuv lub guitar rau soloing. Kuv zam kev muaj ob peb tus pedals vim tias kuv tsis meej pem thiab tsis koom nrog qhov raug, Kuv tsis paub yuav ua li cas ntaus nkauj.

Lwm qhov teeb meem uas tshwm sim nrog muaj ob peb tus pedals hauv txoj saw yog tias qee qhov ntawm lawv tsis yog qhov tseeb dhau los. Raws li qhov tshwm sim, yog tias koj tsis siv qhov tsis zoo koj yuav plam qee qhov kev txhais hauv lub teeb liab, txawm tias thaum lub pedals tsis koom nrog. Qee qhov piv txwv ntawm cov ko taw yog: kuv Ibanez TS-10, Crybaby Wah, Boss BF-3 Flanger, koj tau txais lub tswv yim.

Muaj cov pedalboards digital uas tso cai rau koj teeb tsa cov khawm ib tus rau ua ntej txhais ua ke ntawm digitally simulated teebmeem. Tab sis, cuam tshuam nrog kev tsim lub platform digital, thauj thaj ua rau thaj, teeb tsa, thiab lwm yam cuam tshuam rau kuv lub sijhawm loj. Dhau li, lawv yeej tsis yog qhov tseeb hla dhau.

Thaum kawg, Kuv twb muaj tus ko taw thiab kuv nyiam lawv tus kheej. Kuv tuaj yeem teeb tsa tus pedal Kuv xav tau thiab hloov nws cov presets yam tsis xav tau lub khoos phis tawj (lossis kuv lub xov tooj).

Txhua yam ntawm no tau tshawb nrhiav ntau xyoo dhau los, Kuv pib nrhiav qee yam uas yuav:

1. Saib zoo li lub tsheb kauj vab nrog txhua tus khawm khawm muab rau ua ke ntawm kuv cov pedal analog.
2. Hloov tag nrho kuv cov pedals kom hla dhau qhov tseeb thaum lawv tsis siv.
3. Siv qee qhov teeb tsa thev naus laus zis uas yuav tsis xav tau kev siv midi thaj ua rau thaj, khoos phis tawj, lossis lwm yam txuas nrog.
4. Nqi pheej yig.

Kuv pom cov khoom lag luam los ntawm Carl-Martin hu ua Octa-Switch uas yog qhov kuv xav tau, ntawm yuav luag $ 430 nws yog thiab tseem tsis yog rau kuv. Txawm li cas los xij, nws yuav yog lub hauv paus ntawm kuv tus qauv.

Kuv xav tias nws tuaj yeem tsim lub platform nrog kuv cov kev xav tau, tsawg dua li peb lub hlis twg dua li yuav nws los ntawm lub khw. Kuv tsis muaj Octa-Hloov, tsis tau muaj ib tus, lossis ua si nrog nws, yog li kuv tsis paub dab tsi yog sab hauv. Nov yog kuv tus kheej coj.

Txog cov lej, teeb tsa thiab tsim PCB Kuv yuav siv ob qho tib si DIYLC, thiab Dav dawb hau. Kuv yuav siv DIYLC rau cov qauv thaiv uas tsis xav tau PCB, Dav dawb hau rau kev tsim qauv zaum kawg thiab PCB.

Kuv vam tias koj txaus siab rau kuv txoj kev taug.

Kauj Ruam 1: Yuav Ua Li Cas Thiaj Li Ntaus Tus Ntaus Guitar Bypass Pedal ntawm Chain of Pedals (Tseeb Bypass)

Qhov kev sib tham yooj yooj yim no tso cai rau koj hla tus pedal siv 9-pin 3PDT Taw Hloov thiab 4 lub qhov nkag (1/4 mono). Yog tias koj xav ntxiv rau/tawm LED, koj yuav xav tau: ib qho LED, 390 Ohms 1/4 watt resistor, lub roj teeb rau 9V, thiab 9 volts roj teeb.

Siv cov khoom pheej yig tshaj plaws pom hauv Ebay (lub sijhawm sau cov lus qhia no), tus nqi tag nrho yog:

Kauj Ruam 2: Siv Relays Hloov ntawm On/Off Switch

Siv Relays

Nthuav tawm ntawm qhov yooj yim qhib/tawm lub tswv yim hloov pauv, Kuv xav kom muaj peev xwm hla dhau ib txhij ntau dua 1 tus pedal. Ib qho kev daws teeb meem yuav yog siv kev hloov taw uas muaj ob peb DPDT ua ke, ib qho hloov ntawm ib tus ko taw kom ntxiv. Lub tswv yim no tsis muaj txiaj ntsig rau ntau dua 2 lub pedals, yog li kuv muab pov tseg.

Lwm lub tswv yim yuav ua rau ntau qhov hloov pauv DPDT (ib tus pedal) tib lub sijhawm. Lub tswv yim no yog qhov nyuaj vim tias nws txhais tau tias ib tus yuav tsum tau qhib ua ke kom muaj ntau tus footswitches raws li lub pedals xav tau. Raws li kuv tau hais ua ntej, Kuv tsis zoo ntawm kais seev cev.

Lub tswv yim thib peb yog kev txhim kho ntawm qhov kawg no. Kuv txiav txim siab tias kuv tuaj yeem ua rau lub teeb liab qis DPDT txuas (txhua qhov xa tawm ua raws li DPDT hloov), thiab sib txuas ua ke nrog DIP hloov. Kuv tuaj yeem siv DIP hloov nrog ntau tus neeg hloov pauv raws li kev xa khoom (pedals) xav tau.

Hauv txoj kev no kuv yuav tuaj yeem xaiv qhov txuas uas kuv xav qhib thaum twg los tau. Hauv qhov kawg, txhua tus neeg hloov pauv hauv DIP hloov pauv yuav txuas rau lub kauj ntawm Kev Sib Txuas. Ntawm qhov kawg, DIP Hloov yuav txuas rau ib leeg ntawm qhov hloov pauv.

Daim duab 1 yog ua tiav cov txheej txheem rau 8 Kev Tshaj Tawm (8 tus ko taw), Daim duab 2 yog cov ncauj lus kom ntxaws ntawm ntu hloov pauv ntawm Relay 1 (K9), thiab daim ntawv thib 3 yog Eagle Schematic.

Nws yog qhov yooj yim pom tias hla ntu (Daim duab 2) yog qhov zoo ib yam hauv Circuit Court raws li tau tham hauv Kauj Ruam 1. Kuv khaws tib lub npe rau lub jacks (X1, X2, X3, X4), yog li cov lus piav qhia yuav ua li cas hla kev ua haujlwm yog tib lo lus los ntawm lo lus dua li ib qho rau Kauj Ruam 1.

Qhib cov relays:

Hauv qhov ua tiav cov lej rau 8 qhov xa tawm (Daim duab 1) Kuv tau ntxiv hloov transistors (Q1-Q7, Q9), polarization resistors los teeb tsa transistors ua On-Off keyboards (R1 rau R16), 8 hloov DIP Hloov (S1-1 rau S1-8), qhib/tawm hloov (S2) thiab LEDs uas qhia tias qhov txuas txuas tau zoo li cas.

Nrog S1-1 txog S1-8 tus neeg siv xaiv qhov kev sib txuas yuav qhib li cas.

Thaum S2 ua haujlwm, cov transistors xaiv los ntawm S1-1 rau S1-8 tau saturated los ntawm polarization Resistors (R1-8).

Hauv qhov saturation VCE (DC voltage nruab nrab ntawm tus neeg sau thiab tus xa tawm) yog kwv yees li "0 V", yog li VCC tau siv rau qhov kev xaiv txuas xa lawv.

Ib feem ntawm txoj haujlwm no tuaj yeem ua tiav yam tsis muaj lub transistors, siv DIP Hloov thiab S2 rau VCC lossis hauv av. Tab sis kuv txiav txim siab siv qhov kev ua tiav hauv Circuit yog li tsis muaj qhov xav tau kev piav qhia ntxiv thaum lub logic ib feem ntxiv.

Cov diodes rov qab, sib npaug rau cov xa hluav taws xob coils, tiv thaiv lub Circuit Court los ntawm kev hloov pauv tau tsim nrog kev ua kom/ua kom tsis muaj zog ntawm kev xa tawm. Lawv paub tias ya rov qab lossis flywheels diodes.

Kauj Ruam 3: Ntxiv Kev Sib Txuas Ntxiv (AKA Ntau DIP Hloov)

Cov kauj ruam tom ntej yog xav seb yuav ntxiv ntau yam ntxiv rau lub tswv yim li cas. Thaum kawg kuv xav kom muaj ob peb qhov ua tau ua ke ntawm cov pedals uas tau xaiv los ntawm kev nias sib txawv taw taw. Piv txwv li kuv xav kom muaj tus ko taw 1, 2 thiab 7 ua haujlwm thaum kuv nias ib txhais taw hloov; thiab kuv xav tau pedals 2, 4 thiab 8 thaum kuv nias lwm tus.

Kev daws yog ntxiv DIP Hloov thiab lwm txoj kev hloov taw, Daim duab 3. Ua haujlwm tau zoo nws yog tib lub Circuit Court dua li qhov tau piav qhia hauv KAUJ RUAM dhau los.

Txheeb xyuas lub Circuit Court yam tsis muaj diodes (Daim duab 3) ib qho teeb meem tshwm sim.

S2 thiab S4 xaiv qhov hloov pauv DIP yuav ua haujlwm li cas thiab txhua qhov hloov DIP uas ua ke ntawm kev sib txuas yuav nyob.

Rau 2 qhov kev xaiv piav qhia hauv thawj kab lus ntawm KAUJ RUAM DIP Hloov yuav tsum tau teeb tsa raws li hauv qab no:

• S1-1: ON; S1-2: ON; S1-3 rau S1-6: OFF; S1-7: ON; S1-8: TUAJ
• S3-1: OFF; S3-2: ON; S3-3: OFF; S3-4: ON; S3-5 TO S3-7: OFF; S3-8: YOG

Thaum nias S2, cov hloov pauv S1-X uas yog ON yuav qhib qhov raug xa mus, tab sis S3-4 thiab S3-8 kuj tseem yuav raug qhib los ntawm kev hla S1-2 // S3-2. Txawm hais tias S4 tsis yog av S3-4 thiab S3-8, lawv tau tsaws ntawm S3-2.

Kev daws teeb meem no yog ntxiv diodes (D9-D24) uas yuav tawm tsam ib qho kev txiav luv (Daim duab 4). Tam sim no hauv tib qho piv txwv thaum S2-2 nyob ntawm 0 V D18 tsis ua. Nws tsis muaj teeb meem li cas S-3 thiab S3-8 tau teeb tsa, D18 yuav tsis tso cai rau txhua qhov ntws ntawm tam sim no. Q3 thiab Q7 yuav nyob twj ywm.

Daim duab 5 yog ntu ntu txuas ntxiv ntawm kev tsim qauv suav nrog 2 DIP Hloov, 2 Hloov Hloov Taw, thiab diodes.

Eagle Schematic rau ntu no kuj suav nrog.

Kauj Ruam 4: Ntxiv Logic thiab Momentary Hloov (Pedalboard)

Txawm hais tias qhov yooj yim Circuit piav qhia kom deb li deb tuaj yeem txuas nrog ntau DIP hloov pauv raws li kev sib txuas ntawm cov pedals xav tau, tseem muaj qhov tsis zoo. Tus neeg siv yuav tsum tau qhib thiab deactivate footswitches ib los ntawm ib qho raws li kev sib xyaw ua ke.

Hauv lwm lo lus, yog tias koj muaj ob peb DIP Hloov, thiab koj xav tau cov pedals ntawm DIP Hloov 1, koj yuav tsum qhib lub ko taw hloov pauv thiab tshem tawm lwm qhov kev hloov pauv. Yog tias tsis yog, koj yuav suav nrog cov teebmeem hauv ntau DIP hloov pauv raws li koj tau ua haujlwm ib txhij.

Qhov kev daws teeb meem no ua rau tus neeg siv lub neej yooj yim dua hauv qhov kev nkag siab tias tsuas yog 1 tus footswitch koj tuaj yeem qhib ob peb lub pedals tib lub sijhawm. Nws tsis xav kom koj qhib txhua lub zog pedal ib tus zuj zus. Tus qauv tsim tseem tuaj yeem txhim kho.

Kuv xav qhib DIP cov hloov pauv tsis yog siv lub taw taw uas ib txwm qhib lossis tawm, tab sis nrog qhov hloov pauv ib ntus uas "nco qab" kuv qhov kev xaiv kom txog thaum kuv xaiv lwm DIP Hloov. Ib qho hluav taws xob "latch".

Kuv txiav txim siab tias 8 qhov sib txawv sib txuam ua ke ntawm 8 tus pedals yuav txaus rau kuv daim ntawv thov thiab nws ua rau txoj haujlwm no piv rau Octa-hloov. 8 qhov sib txawv ntawm kev teeb tsa ua ke txhais tau tias 8 tus hloov pauv, 8 tus ntiv taw txhais tau tias yog 8 qhov txuas thiab cuam tshuam nrog kev sib txuas.

Xaiv lub latch:

Kuv xaiv lub Octal ntug ua rau D hom Flip Flop 74AC534, qhov no yog tus kheej xaiv thiab kuv xav tias yuav muaj lwm yam IC's uas yuav haum rau daim nqi.

Raws li cov ntawv teev tseg: "Ntawm qhov hloov pauv ntawm lub moos (CLK) cov tswv yim, Q cov lus tso tawm tau teeb tsa ua kom tiav ntawm cov qib kev xav uas tau teeb tsa ntawm cov ntaub ntawv (D) cov tswv yim".

Qhov tseem ceeb txhais rau: txhua zaus tus pin CLK "pom" tus mem tes mus los ntawm 0 txog 1 IC "nyeem" lub xeev ntawm 8 cov ntaub ntawv nkag (1D txog 8D) thiab teeb tsa 8 cov ntaub ntawv tawm (1Q/ rau 8Q/) raws li qhov ua tiav ntawm cov tswv yim coj.

Hauv lwm lub sijhawm, nrog OE/ txuas nrog hauv av, cov ntaub ntawv tso tawm khaws tus nqi nyeem thaum lub sijhawm kawg CLK 0 rau 1 kev hloov pauv.

Cov tswv yim Circuit Court:

Rau qhov hloov pauv kuv xaiv SPST Momentary Switches ($ 1.63 hauv eBay), thiab teeb tsa lawv raws li qhia hauv daim duab 6. Nws yog qhov yooj yim Rub tawm hauv Circuit Court, nrog lub de-bounce capacitor.

Thaum so, tus tiv thaiv rub cov zis 1D rau VCC (Siab), thaum lub sijhawm hloov pauv tau qhib 1D raug rub mus rau hauv av (Tsawg). Lub tshuab hluav taws xob tshem tawm qhov hloov pauv cuam tshuam nrog kev ua kom/deactivation ntawm qhov hloov pauv ib ntus.

Muab cov khoom ua ke:

Qhov kawg ntawm ntu no yuav yog ntxiv Schmitt-Trigger inverters, uas yuav: a) muab cov mem tes zoo rau Flip Flop cov tswv yim, b) qhia meej ntxiv ib qho ntxiv uas tau tsim thaum lub sij hawm hloov mus. Daim duab ua tiav tau qhia hauv daim duab 7.

Thaum kawg kuv ntxiv teeb tsa ntawm 8 LED's hauv Flip Flop outputs uas mus "ON" qhia qhov DIP Hloov tau xaiv dab tsi.

Eagle schematic suav nrog.

Kauj Ruam 5: Kev Tsim Tsa Kawg - Ntxiv Lub Sijhawm Teeb Meem thiab DIP Hloov Qhov Taw Qhia LEDs

Mloog Teeb Meem Tiam

Txog lub moos teeb liab kuv txiav txim siab siv "LOS YOG" rooj vag 74LS32. Thaum ib qho ntawm cov inverters 'cov txiaj ntsig yog 1 (hloov nias) tus pin CLK ntawm 74LS534 pom qhov kev hloov pauv los ntawm qis mus rau siab tsim los ntawm cov saw ntawm LOSSIS lub rooj vag. Cov saw ntawm cov rooj vag no tseem ua rau qeeb me me ntawm lub teeb liab mus txog CLK. Qhov no paub tseeb tias thaum CLK tus pin ntawm 74LS534 pom lub teeb liab los ntawm qis mus rau siab, twb muaj Lub Xeev Siab lossis Tsawg hauv cov tswv yim.

74LS534 "nyeem" dab tsi inverter (hloov pauv ib ntus) raug nias, thiab tso "0" hauv cov khoom sib xws. Tom qab kev hloov pauv los ntawm L mus rau H hauv CLK lub xeev ntawm 74LS534 cov zis raug kaw kom txog thaum mus txog rau lub hlis tom ntej.

Tsim kom tiav

Kev ua tiav tiav kuj suav nrog LED's uas qhia tias lub pedal ua haujlwm li cas.

Daim duab 8 thiab schematics suav nrog.

Kauj Ruam 6: Pawg Tswj Xyuas Logic - Tsim Dav Hlau

Kuv yuav tsim 3 pawg sib txawv:

Kauj Ruam 8: Hloov Pawg Thawj Coj

Kwv yees tus nqi polarization resistors

Txij ntawm no mus kuv yuav tsum xam tus nqi ntawm cov polarization resistors uas txuas rau transistors. Rau transistor yuav tsum tau saturated.

Hauv kuv qhov kev tsim thawj zaug kuv tso cov LEDs uas qhia tias lub pedal tau ua haujlwm li cas ua ntej lub transistors uas qhib qhov txuas, ua li no lawv yuav ntws tam sim no ncaj qha los ntawm 74LS534. Qhov no yog tsim tsis zoo. Thaum kuv paub qhov kev ua yuam kev no kuv tso cov LEDs ua ke nrog Relay coils, thiab ntxiv qhov tam sim no rau kev sib hloov transistor polarization.

Cov kis uas kuv siv yog JRC 27F/005S. Cov kauj siv 200mW, cov yam ntxwv hluav taws xob yog:

Naj Npawb	Chev Voltage VDC	Txais Voltage VDC (Max.)	Tawm Tawm Voltage VDC (Min.)	Chev Kuj ± 10%	Tso Voltage VDC (Max.)
005-TSO	5	3.75	0.5	125	10

IC = [200mW / (VCC-VCEsat)] + 20mA (LED tam sim no) = [200mW / (5-0.3) V] + 20mA = 60 mA

IB = 60mA / HFE = 60mA / 125 (yam tsawg kawg HFE rau BC557) = 0.48 mA

Siv lub Circuit Court hauv daim duab 9:

R2 = (VCC - VBE - VD1) / (IB * 1.30) -> Qhov twg VCC = 5V, VBE yog qhov hluav taws xob ntawm Base -Emitter txuas, VD1 yog Voltage ntawm Diode D1 ntawm ncaj qha. Cov diode no yog cov diode uas kuv tau ntxiv kom tsis txhob qhib kev ua haujlwm tsis raug, piav qhia hauv Kauj Ruam 3. Kom ntseeg tau tias kuv yuav siv qhov siab tshaj VBE rau BC557 uas yog 0.75 V thiab nce IB tam sim no 30%.

R2 = (5V - 0.75V - 0.7 V) / (0.48 mA * 1.3) = 5700 Ohms -> Kuv yuav siv qhov qub 6.2K tus nqi

R1 yog rub tawm tus tiv thaiv thiab kuv yuav coj nws li 10 x R2 -> R1 = 62K

Relay Board

Txog rau pawg thawj coj saib xyuas kuv tau zam kev ntxiv 1/4 jacks rau hauv nws yog li kuv tuaj yeem ua qhov seem hauv qhov chaw ua haujlwm ntawm dawb version ntawm Eagle.

Kauj Ruam 9: Ua tiav Pedal Board thiab Xaus

Ua tiav Pedal Board

Ua tiav cov txheej txheem ntawm lub rooj tsav tsheb nrog daim ntawv lo ntxiv rau txhua ntu (cov laug cam sib tham hauv cov kauj ruam dhau los) txuas nrog. Tsis tas li kuv ntxiv-p.webp

Qhov kev ntsuas zaum kawg yog qhov tso tawm jacks txuas ob qho tib si ntawm lawv thiab mus rau pawg thawj coj saib xyuas.

Xaus

Lub hauv paus ntawm tsab xov xwm no yog txhawm rau tsim Txoj Haujlwm Muaj Tseeb Bypass Guitar Effect Looper Station Siv Dip Hloov uas:

1. Saib zoo li lub tsheb kauj vab nrog txhua tus khawm khawm muab rau ua ke ntawm kuv cov pedal analog.
2. Hloov tag nrho kuv cov pedals kom hla dhau qhov tseeb thaum lawv tsis siv.
3. Siv qee qhov teeb tsa thev naus laus zis uas yuav tsis xav tau kev siv midi thaj ua rau thaj, khoos phis tawj, lossis lwm yam txuas nrog.
4. Nqi pheej yig.

Kuv txaus siab qhov khoom kawg. Kuv ntseeg tias nws tuaj yeem txhim kho tau tab sis tib lub sijhawm kuv ntseeg tias txhua lub hom phiaj tau them thiab qhov tseeb nws pheej yig.

Kuv tam sim no paub tias qhov yooj yim Circuit no tuaj yeem siv los xaiv tsis yog cov pedals nkaus xwb tabsis tseem yuav qhib thiab kaw lwm yam khoom siv, Kuv yuav tshawb nrhiav txoj hauv kev ntawd ib yam.

Ua tsaug rau koj taug txoj kev no nrog kuv, thov koj xav qhia kev txhim kho.

Kuv vam tias tsab xov xwm no yuav ua rau koj sim.

Kauj Ruam 10: Cov peev txheej ntxiv - DIYLC Tsim

Kuv txiav txim siab los ua 1st tsab qauv ntawm kev siv DIYLC (https://diy-fever.com/software/diylc/). Nws tsis muaj zog li Eagle, qhov tsis zoo yog qhov koj tsis tuaj yeem tsim cov phiaj xwm thiab tsim cov phiaj xwm phiaj xwm los ntawm nws. Hauv daim ntawv thov no koj yuav tsum tsim PCB txheej txheem los ntawm txhais tes. Tsis tas li yog tias koj xav kom lwm tus los ua cov laug cam, feem ntau cov tuam txhab tsuas lees txais Eagle cov qauv. Qhov kom zoo dua yog tias kuv tuaj yeem tso tag nrho DIP hloov pauv hauv 1 lub rooj tsavxwm.

Kuv siv ob txheej txheej Copper Clad PCB rau cov logic board thiab ib txheej tooj liab clad PCB rau DIP Switch Board thiab Relay Board.

Hauv pawg thawj coj saib kuv tab tom ntxiv ib qho piv txwv (ncig) ntawm yuav ua li cas txuas cov LEDs uas yuav qhia tau tias DIP Hloov Li Cas yog ON.

Txhawm rau ua PCBs los ntawm DIYLC koj yuav tsum:

1. Xaiv lub rooj tsavxwm los ua haujlwm (Kuv tab tom muab 3 lub laug cam ua ntej) thiab qhib nws nrog DIYLC
2. Hauv cov ntawv qhia zaub mov, xaiv "File"
3. Koj tuaj yeem xa cov phiaj xwm txheej rau PDF lossis PNG. Ib qho piv txwv ntawm Logic Board teeb tsa xa tawm rau PDF suav nrog.
4. Txhawm rau siv txoj kev hloov pauv mus rau koj tooj liab clad PCB, koj yuav tsum luam tawm qhov no yam tsis ntsuas. Tsis tas li koj yuav tsum hloov xim ntawm cov khoom sib xyaw txheej txheej los ntawm ntsuab rau dub.
5. Tsis txhob hnov qab tsom iav cov khoom ib sab ntawm pawg thawj coj los siv txoj kev hloov pauv.

Hmoov zoo 1:)

Kauj Ruam 11: Annex 2: Xeem

Kuv txaus siab nrog txoj kev uas cov laug cam tawm los siv txoj kev hloov pauv. Tsuas yog lub ntsej muag ob lub ntsej muag yog lub logic board thiab txawm hais tias qee qhov ua tsis raug nws nws tau ua haujlwm zoo xwb.

Rau thawj qhov kev hloov pauv yog thawj qhov teeb tsa raws li hauv qab no:

• DIP hloov 1: hloov 1 ON; keyboards 2 txog 8 OFF
• DIP hloov 2: hloov 1 thiab 2 ON; key 3 txog 8 OFF
• DIP hloov 3: hloov 1 thiab 3 ON; lwm yam hloov OFF
• DIP hloov 4: hloov 1 thiab 4 ON; lwm yam hloov OFF
• DIP hloov 5: hloov 1 thiab 5 ON; lwm yam hloov OFF
• DIP hloov 6: hloov 1 thiab 6 ON; lwm yam hloov OFF
• DIP hloov 7: hloov 1 thiab 7 ON; lwm yam hloov OFF
• DIP hloov 8: hloov 1 thiab 8 ON; lwm yam hloov OFF

Kuv yuav muab tso rau hauv av cov tswv yim 1 txog 8 hauv DIP hloov lub rooj tsavxwm. LED 1 yuav ib txwm nyob, thaum seem yuav ua raws ntu.

Tom qab ntawd kuv tig ob peb qhov hloov pauv thiab sim dua. Ua tau zoo!
