Nov yog qhov piv txwv rau ua lub USB them nyiaj thaum muaj xwm ceev nrog lub hnub ci cell.
Hauv qhov no kuv siv lub hnub ci 12V. Kuv rov ua dua lwm cov khoom siv los ntawm lub khoos phis tawj qub.
Nws tau tswj hwm ntawm 5V 1A nrog qhov kev tsim no, rau kev siv tam sim no siab dua LM1084 (5A) hloov LM7805.
Kauj Ruam 1: Daim Ntawv Teev Npe
Txhawm rau ua qhov no koj xav tau:
-12V lub hnub ci vaj huam sib luag
- Veroboard 7cm*5cm https://fr.aliexpress.com/w/wh Wholesale-veroboard.ht…
-330uF 25V capacitor electrolytic https://www.aliexpress.com/w/wh Wholesale-capacitor-…
-100uF 10V capacitor electrolytic https://www.aliexpress.com/w/wh Wholesale-capacitor-…
-LM7805 tus tswj hluav taws xob
-270 ohm resistor https://www.aliexpress.com/w/wh Wholesale-resistor-k…
- 3mm Led Green
- Headers txuas (rau arduino project siv hauv kuv kis)
-USB txuas https://www.aliexpress.com/w/wh Wholesale-usb-female…
Kauj ruam 2: Schematic thiab Soldering
Fwm cov txheej txheem thiab cov khoom sib txuas ntawm qhov chaw zoo
Siv C1 capacitor nrog qhov hluav taws xob siab dua qhov input voltage! (25V zoo rau kuv)
Ua ntej soldering hnub ci cell, tig rov qab lub vaj huam sib luag rau tsim 0V.
Soldering nyob rau hauv qhov hluav taws xob tuaj yeem ua rau lub zog puas
Nws yog ib qho yooj yim schematic.
Kauj Ruam 3: Xeem Nrog Hnub Ci Ci
Muab koj lub vaj huam sib luag tso rau pem hauv ntej ntawm lub hnub kom pom cov coj ci ci.
Koj lub hnub ci them nyiaj thaum muaj xwm ceev tuaj yeem ua haujlwm.
Nws nyob ntawm seb hom vaj huam sib luag hnub ci rau them lub sijhawm.
Tsis tas li koj tuaj yeem txhawb lub phiaj xwm vaj tsev arduino.
LM7805 yog txwv ntawm 1A max yog li rau qhov siab dua tam sim no. (LT1086 rau 1.5A lossis LM1084 rau 5A)
