Hauv kab ntawv no kuv yuav qhia yuav ua li cas thiaj ua Dual Channel Vu meter siv LM3914 IC. Koj tuaj yeem saib cov vis dis aus txuas nrog rau kev tshaj tawm rau kev tsim kho tiav & ua haujlwm ntawm qhov haujlwm lossis txuas ntxiv nyeem cov ntawv

Kauj Ruam 1: Cov Cheeb Tsam Yuav Tsum Tau

Rau qhov haujlwm no koj tsuas xav tau ob peb yam

• 2 * LWM 3914
• 2 * IC Qhov (Socket)
• 2 * 1K hmo
• 2 * 10K Trimmer
• 10 * Ntsuab LED
• 6 * Daj LED
• 4 * Liab LED
• 2 * 3.5mm Suab Jack
• 1 * DC nkaus
• 1 * Hloov

Koj tuaj yeem yuav cov khoom lag luam saum toj no los ntawm cov koom tes hauv qab no txuas uas yuav pab kuv ntau txoj hauv kev.

Kauj Ruam 2: Daim Duab Circuit & PCB Fabrication

Kuv tsim kuv lub voj voog siv KICAD & kuaj lub Circuit Court ntawm lub khob cij & tom qab ntawd tsim kuv li PCB txheej txheem & tsim cov ntaub ntawv gerber & laum rau kev tsim. Txog kev tsim khoom kuv tau siv JLCPCB.com uas muab pheej yig heev & ua tau zoo PCB rau tsuas yog 2 $ (5 daim).

Kev tsim hluav taws xob feem ntau nyob ib puag ncig LM3914. Txog qhov haujlwm no kuv yuav tsum siv ob LM3914 vim kuv xav cais cov kws tshuaj rau txhua tus channel xws li yog & sab laug. Txhua tus kws tshuaj ntsuam sab kuj tseem muab lub tshuab txiav, uas tuaj yeem siv los ntsuas ntsuas. Lub voj voog no xav tau 12 Volts 1Amp zog rau kev ua haujlwm.

Kauj Ruam 3: Sib dhos & Xeem

Tom qab tau txais lub rooj tsavxwm kuv tau teeb tsa tag nrho cov khoom siv raws li lawv cov ntawv sau tseg.

Tom qab kev txhim kho txhua qhov khoom siv, kuv txuas lub Circuit Court mus rau 12v lub zog hluav taws xob & tom qab ntawd txuas nrog lub suab tawm los ntawm lub khoos phis tawj & tseem txuas nrog ib qho ntxiv rau lub suab nrov.

Nco tseg: Tom qab koj ua lub zog hluav taws xob & txuas nws mus rau lub tswv yim yuav tsum tsis muaj LED On. Yog tias muaj ib qho LED nyob tom qab kho lub trimmer xws li txhua qhov LED tau tawm.

Tom qab txhua qhov kev sib txuas & ntsuas ntsuas tau ua tiav, tom qab ntawd yam kawg uas tshuav yog ua nkauj.

Kuj tseem ceeb: thaum koj ua nkauj & yog tias koj lub LED tsis ua haujlwm ces kho lub trimmer kom txog thaum koj pom LED On.
