Tom qab Christmas koj yuav tau txais qee lub teeb tawg uas tsis ua rau pom kev ntxiv lawm. Koj tuaj yeem siv lawv rau ntau qhov haujlwm cuam tshuam zoo li piv txwv qhov no. Nws 1.5V Roj teeb ntsuas uas siv tsob ntoo Christmas teeb ua cov zaub.

Kauj Ruam 1: Yam Yuav Tsum Tau Ua

Txoj haujlwm no tsis xav tau ntau qhov, ntawm no yog cov npe ntawm lawv:

-Prototyping Board (lossis tej zaum txawm tias ob daim Prototyping Boards)

-ULN2003 IB

-2 LM324 ICs

-2 DIP14 IC Qhov (Socket)

-DIP16 IC Qhov (Socket)

-6 1KΩ Resistos (xim av, dub, liab, kub)

-10KΩ Resistor (xim av, dub, txiv kab ntxwv, kub)

-33KΩ Resistor (txiv kab ntxwv, txiv kab ntxwv, txiv kab ntxwv, kub)

-7 Christmas Ntoo Teeb

-Qee cov xov hlau

Kauj ruam 2: Schematic

Schematic yuav zoo li nyuaj tab sis nws tsis yog.

Circuit siv 2 LM324 OP-AMP ICs los sib piv cov tswv yim hluav taws xob nrog cov ntsuas hluav taws xob tau teeb tsa los ntawm tus tiv thaiv ntaiv, tom qab ntawd cov ICs tawm mus rau ULN2003 IC. IC no muaj 7 lub transistors uas tuaj yeem ua haujlwm tam sim no ntawm cov teeb (nws nyob ib puag ncig 200mA).

Kauj Ruam 3: Npaj Teeb

Qhov no yog txheej txheem yooj yim heev.

Kauj Ruam 1: Siv lub teeb tawm koj yuav tsum xaus nrog ib lub teeb zoo li nws tau qhia hauv daim duab sab xis.

Kauj Ruam 2: Khoov cov leeds zoo li hauv nruab nrab daim duab.

Kauj Ruam 3: Maj mam rub lub teeb los ntawm nws rooj plaub ntsuab.

Kauj Ruam 4: Xuab zeb daim ntawv leeds, lawv muaj kev sib cais uas ua rau siv tawv tawv heev.

Kauj ruam 5: Nws ua tiav.

Kauj Ruam 4: Solder ULN2003 thiab Teeb

Kev teeb lub teeb yog ib qho nyuaj tab sis nws ua tau, tsuas yog xyuas kom nws ua kev sib cuag tau zoo thiab koj tsis ua dab tsi luv. Kuv tau ua qhov Circuit Court no ntawm ob lub rooj sib cais yog li kuv tau siv cov xim muaj hlau uas tau qhia ntawm daim duab sab xis. Thaum kawg ntawm kab ntawv kuv tau siv GOLDPINs kom tshem tawm pawg thawj coj no thiab tuaj yeem siv nws hauv qee qhov haujlwm. Yog tias koj tab tom tsim cov kab hluav taws xob no ntawm ib lub rooj tsav xwm koj tsis xav tau cov kab no.

Kauj Ruam 5: Xeem Pawg Thawj Coj

Txuas lub rooj tsavxwm rau 5V Cov Khoom Siv Hluav Taws Xob, Nws yuav tsum muaj peev xwm xa yam tsawg kawg yog 1.4A vim tias teeb teeb ntau tam sim no (ncig 0.2A). Peb muaj 7 lub teeb yog li 7 zaug 0.2A sib npaug 1.4A. Thaum koj txuas 5V rau cov tswv yim ntawm IC teeb yuav tsum teeb.

Kauj Ruam 6: Ua kom Pawg Neeg Saib Xyuas Ntev Dua

Ntxuav lub rooj tsavxwm nrog PCB huv. Ruaj lub teeb nrog Kub Glue zoo li nws tau qhia hauv daim duab thiab ruaj ntseg hauv qab ntawm pawg thawj coj nrog daim kab xev hluav taws xob zoo li nws tau qhia hauv daim duab.

Kauj Ruam 7: Solder Second Board

Pawg thawj coj no yooj yim rau sib sau ua ke tab sis nws tuaj yeem cuam tshuam zoo li hauv kuv qhov xwm txheej. Ntawm daim duab koj tuaj yeem pom qhov tshawb pom loj ntawm cov xov hlau. Feem ntau thaum tsis muaj dab tsi txuas nrog rau cov tswv yim txhua lub teeb yuav ci, yog tias koj xav kom xiam cov yam ntxwv no solder 1kΩ resistor ntawm roj teeb ntxiv rau xaim thiab hauv av.

Kauj Ruam 8: Ruaj Ntseg Pawg Thib Ob

Ntxuav lub rooj tsavxwm nrog PCB kom huv thiab nyab xeeb hauv qab ntawm pawg thawj coj nrog daim kab xev hluav taws xob zoo li nws tau qhia hauv daim duab. Zoo li nrog pawg thawj coj yav dhau los.

Kauj Ruam 9: Kuaj Ob Pawg

Yog tias koj ua txhua yam zoo ob yam tuaj yeem tshwm sim. Txhua lub teeb yuav qhib lossis kaw. Yog tias koj tau siv cov tshuaj tiv thaiv ntxiv 1kΩ lawv yuav tsum tau tawm thiab yog tias koj tsis yog lawv yuav tsum nyob. Txij ntawm no nws ua haujlwm thiab koj tuaj yeem sim qee lub roj teeb.

Kauj Ruam 10: Kuaj Ob Pawg Thawj Coj Ua Ke

Yooj yim heev koj tuaj yeem siv cov kua nplaum kub lossis qee daim kab xev lossis txhua yam uas koj xav tau. Yog tias koj siv ib lub rooj tsavxwm koj tuaj yeem hla cov kauj ruam no.

Kauj Ruam 11: Txuas Cov Hlau

Nco ntsoov tias koj txuas nws hauv txoj cai polarity tab sis yog koj ua yuam kev koj yuav tsis ua kom puas tsuaj dab tsi. Tom qab ntawd khawm cov xaim thiab ruaj ntseg nws nrog qee daim kab xev lossis qee yam.

Kauj Ruam 12: Txaus Siab Rau Koj Tus Kheej Tshiab

Ua tsaug rau kev nyeem kuv cov lus qhia, thov txim rau txhua qhov kuv ua yuam kev.
