Hauv cov lus qhia no kuv yuav qhia koj yuav ua li cas thiaj ua DIY hnab tshos loj DC qhov ntsuas hluav taws xob nrog piezo buzzer rau kev tshuaj xyuas ntawm koj tus kheej. Txhua yam koj xav tau yog kev paub pib hauv tshuab hluav taws xob thiab siv sijhawm me ntsis.

Yog tias koj muaj lus nug lossis teeb meem koj tuaj yeem tiv tauj kuv ntawm kuv tus email: [email protected]

Qee qhov khoom siv tau muab los ntawm DFRobot.

Yog li cia pib

Kauj Ruam 1: Lub Tswv Yim Tswv Yim

Lub tswv yim tom qab txoj haujlwm no yooj yim heev, txhawm rau ntsuas DC qhov ntsuas hluav taws xob uas haum rau hauv hnab tshos nrog piezo buzzer rau tshuaj xyuas cov kab hluav taws xob.

Kauj ruam 2: Cov ntaub ntawv

Cov ntaub ntawv xav tau rau txoj haujlwm no tuaj yeem yuav ntawm ebay, amazon lossis koj lub khw hluav taws xob hauv ib cheeb tsam.

Rau qhov haujlwm no koj yuav xav tau:

-DC ntsuas hluav taws xob

-9V roj teeb

-tsis buzzer

-2-txoj kev toggle hloov, koj tseem tuaj yeem siv 2-txoj kev swb swb

-9V roj teeb txuas

-PLA filament

Banana qhov (liab thiab dub)

Kauj Ruam 3: Vaj Tsev

Ua ntej kuv xav tau los ntsuas txhua yam khoom, yog li kuv tau pom kwv yees li cas lub tsev loj kuv yuav tsum tau ua.

Medidas: 60 x 20 x 85 mm

Tom qab ntawd kuv tau tsim cov duab kos hauv qhov program rau ua qauv 3D, STL cov ntaub ntawv ntawm ob tus qauv 3D no tau txuas nrog.

Vaj tse tau luam tawm 3D nrog cov PLA dawb filament. Nws tau ua los ntawm ob ntu, rooj plaub tseem ceeb thiab npog. Tom qab ntawv npog nrog plaub tus ntsia hlau rau ntawm rooj plaub tseem ceeb. Ntawm sab xub ntiag muaj ib qho qhib rau ntxig lub ntsuas hluav taws xob thiab ob lub qhov me me rau cov txiv tsawb.

Ntawm sab laug yog qhib rau lub toggle hloov lossis swb swb.

Kauj ruam 4: Kev thaiv kab

Rau cov khoom siv kuv tau siv 9 V roj teeb, feem ntau yog vim nws qhov sib piv ntawm qhov loj thiab muaj peev xwm. Feem ntau ntawm cov cuab yeej ntsuas digital siv 9 V roj teeb raws li khoom siv.

Roj teeb txuas nrog toggle hloov, uas koj tuaj yeem xaiv ntawm ntsuas DC voltage lossis ntsuas qhov Circuit Court nrog piezo buzzer.

Kuv tau txuas daim duab kab xev kom koj tuaj yeem pom yuav ua li cas txuas txhua yam.

Kauj ruam 5: Xeem

Tom qab thaum tag nrho cov xov hluav taws xob tau ua tiav, Kuv ntsia ua qee qhov kev sim. Kuv tau siv Velleman digital multimeter rau ntsuas ntsuas kev sib piv. Peb yuav tsum paub tias qhov ntsuas hluav taws xob DIY no tsis muaj ntsuas ntsuas cov xov hlau, yog li peb tuaj yeem cia siab tias qee qhov yuam kev hauv cov txiaj ntsig.

Rau kev xa khoom Kuv tau siv Li-Ion roj teeb (li 4.2V). Tom qab ntawd kuv tau ntsuas qhov hluav taws xob nrog DIY qhov ntsuas hluav taws xob thiab Velleman digital multimeter. Cov txiaj ntsig tau tshwm sim tsis txaus ntseeg, vim tias kuv tau cia siab tias ua yuam kev ntau dua hauv kev ntsuas ntsuas.

1.test:

Velleman digital multimeter -> tshwm sim = 4.12 V

DIY digital voltmeter -> txiaj ntsig = 4.17 V

Raws li nws tuaj yeem pom los ntawm qhov tshwm sim, qhov sib txawv hauv 1.test yog li 0.05 V.

2. kev xeem

Velleman digital multimeter -> tau = 4.02 VDIY digital voltmeter -> tshwm sim = 4.06 V

Qhov tshwm sim thib ob yog qhov zoo me ntsis, 0.04 V sib txawv.

Hauv qhov kev xaus peb tuaj yeem pom qhov ntawd, qhov sib txawv hauv cov txiaj ntsig yog kwv yees li 0.045 V. Rau kev sib piv zoo dua, nws yuav xav tau los ntsuas ntau ntxiv (min. 10) thiab tom qab ntawd suav cov lej nruab nrab.
