Qhov no yog qhov yooj yim siv thiab pheej yig DIY Voltmeter. Tag nrho tus nqi ntawm kev ua txoj haujlwm no tsawg dua INR 200 lossis 2.5 $ nkaus xwb.
Kauj Ruam 1: Daim Ntawv Teev Npe
Cov cheebtsam xav tau rau txoj haujlwm no tau teev tseg hauv qab no -
SIB 4148x3

R 10K X 1
VR 10K X 1
Kauj Ruam 2: Daim duab Circuit Court
Nov yog Circuit Diagram rau qhov haujlwm.
Kauj Ruam 3: PCB Tsim
Nov yog PCB Tsim rau txoj haujlwm no.
Kauj Ruam 4: Ua Tus Txheej Txheem
Kev tsim PCB tau ua los ntawm EasyEDA.com thiab kev xaj xaj yog ua los ntawm jlcpcb.com uas tseem yog tus txhawb nqa txoj haujlwm no. Lawv muab cov kev cai ua tau zoo tshaj plaws pcbs rau tus nqi qis tshaj hauv khw. Evenm lawv txiav lawv tus nqi kom maj nrawm!
Tom qab tau txais pcbs Kuv Soldered txhua yam khoom siv hauv qhov chaw thiab sim nws nrog roj teeb. kuv piv ob qho yuav ib qho thiab ib qho diy. ob leeg yog kwv yees tib yam.
