2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:30
Micro PSU txhawm rau lub zog rau lub khob cij nrog 5 volts.
Txuas mus rau 9V roj teeb, 12V lossis lwm lub zog DC los ntawm 8 txog 18 volts.
Kauj Ruam 1: Cheeb Tsam
Txhawm rau tsim qhov no koj xav tau:
- Qee qhov txuj ci hluav taws xob. Soldering, paub yuav ua li cas ua raws daim duab qhia chaw thiab lwm yam..
- 1 qhov ntsuas hluav taws xob LM 7805
- 1 10uF capacitor
- 1 1000uF capacitor (koj tuaj yeem siv ib qho loj electrolyt capacitor ntawm no, tsis tas yuav yog raws nraim 1000uF)
- 1 100 nF capacitor
- 1 LED rau lub zog ntawm qhov taw qhia
- 1 tus tiv thaiv kom coj qhov hluav taws xob nqis los ntawm 5V mus rau qhov koj lub LED khiav ntawm
- 1 lub dav hlau ntsia hlau rau qhov hluav taws xob nkag
- 1 hloov rau cov tswv yim hluav taws xob qhib/tua
- 1 perfboard, hom nrog tooj liab qhov muag, tsis yog kab txaij
- 1 2-tus pin txuas rau ntsaws chav nyob rau hauv lub khob cij
Resistor xam R = ohm ntawm resistorV = qhov hluav taws xob rau LED (Koj tuaj yeem pom qhov no hauv cov ntawv teev tseg rau koj li LED) Kuv = tam sim no rau LED (tseem tuaj yeem pom hauv daim ntawv teev npe) R = (5-V) / Tom qab ntawd tus nqi tiv thaiv ze tshaj plaws uas koj tuaj yeem pom.
Kauj ruam 2: Tsawg
Muab tag nrho cov khoom siv tso rau ntawm daim tawv nqaij kom pom qhov me me uas koj tuaj yeem ua tau.
Kuv yuav tsis muab cov lus qhia ntxaws ntawm no, vim qhov loj thiab teeb tsa ntawm cov khoom koj siv yuav txawv ntawm kuv. Muab cov khoom sib dhos kom nruj raws li koj tuaj yeem ua tau, thaum txheeb xyuas qhov tseeb koj tuaj yeem ua tiav qhov Circuit Court nyob hauv qab ntawm lub rooj tsavxwm yam tsis ntxiv cov xov hlau. Thaum koj tau pom koj qhov loj me me, txiav tawm daim uas koj xav tau.
Kauj ruam 3: Cov laug cam
thaum koj tau txiav txim siab txoj hauv kev los nyem koj cov khoom sib xyaw ua ke, nws yog lub sijhawm siv lub tshuab ziab khaub ncaws.
Txheeb cov duab kom pom tias kuv tau ua li cas.
Kauj ruam 4: Txaus siab rau
Txuas nws rau hauv koj daim ntawv qhia zaub mov thiab pib siv

Bling Tawm Koj Cov Ntawv Cij (yuav ua li cas Ntxiv LED Qhia Qhov Taw Qhia rau Solarbotics Pob Zeb Breadboard): Cov pob zeb ci pob tshab no zoo ib yam li lwm yam khoom siv hluav taws xob, tab sis lawv meej! Yog li, ib tus tuaj yeem ua dab tsi nrog daim ntawv qhia zaub mov kom meej? Kuv xav tias cov lus teb pom tseeb yog ntxiv lub zog LEDs
Me me Breadboard 5v PSU (nrog Ob Txoj Kev Tawm): 5 Kauj Ruam
Me me Breadboard 5v PSU (nrog Ob Txoj Kev Tso Tawm): Qhov me me sib cais 5 volt PSU yog qhov zoo tshaj plaws rau cov phiaj xwm phiajcim.
