2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26
Thawj SmartTAG (Malaysia) los nrog LCD tsis muaj lub teeb pom kev, qhov no yog qhov tsis yooj yim los tshuaj xyuas daim npav tshuav nyiaj li cas nyob hauv qhov chaw tsis pom kev zoo. Kuv pom kuv tus phooj ywg BP Tan hloov kho ib chav kom tau txais lub teeb pom kev, nws tau zoo siab qhia kuv thiab muab qee qhov LED rau kuv hloov kho. Saib cov kauj ruam yooj yim raws li hauv qab no. Cov cuab yeej / ntu yuav tsum tau ua:
- - T10 ntsia hlau tsav tsheb
- - Soldering hlau
- - Super kua nplaum
- - LED x 2 po
- - Hlau
- - Txiav
- - Ob daim kab xev (xaiv tau)
Kauj ruam 1:
KAUJ RUAM 1: Tshem lub hau ntswj me me thiab lub roj teeb npog, tom qab ntawd tshem ob lub T10 ntsia hlau raws li qhia.
Kauj ruam 2:
KAUJ RUAM 2: - Nqa lub npog LCD maj mam siv rab riam nyob ruaj ruaj.
- Solder 2 LEDs hauv koob ua ke nrog 470 ohm chip resistor. Tus nqi tiv thaiv tuaj yeem ua kom tau raws li qhov xav tau ci.
Bound LEDs thiab nti resistor ntawm sab laug sab xis ntawm LCD los ntawm kev siv cov kua nplaum super.
Kauj ruam 3:
KAUJ RUAM 3: - Txuas lub dav hlau LED mus rau PCB. - Anode thiab cathode qhov chaw raws li qhia, thawj qhov chaw cathode nyob ntawm ib qho ntawm lub davhlau ya nyob twg, txawm li cas los xij, Kuv tau txav nws mus rau roj teeb tsis zoo.
Kauj ruam 4:
KAUJ RUAM 4: - Qee tus ua npuas ncauj thiab xim xim cim cwj mem tuaj yeem siv los npog qhov tsis xav tau lub teeb xau. - Rov ua dua lub tsev, tam sim no SmartTAG nrog lub teeb pom kev tau npaj los siv. - Qhov zoo nkauj ntawm qhov kev hloov kho no yog lub teeb yuav raug txiav tawm hauv hom standby.
