Kuv tau tawm mus rau kuv yawg yawg ua liaj ua teb rau lub asthiv no thiab thaum kawg kuv paub tias kuv xav tau qee yam los them kuv lub xov tooj. Tsuas yog qee yam khoom kuv muaj hauv kuv lub tsev lub tswv yim ntawm lub hnub ci them nyiaj tuaj rau kuv, thiab nws ua haujlwm !!!: D Cov ntaub ntawv koj yuav xav tau: -A 6V hnub ci cell, koj tuaj yeem siv 12v solar cell kuj tau. (Kuv siv ob lub 6v solar cells kom tau txais tam sim no ntau dua)-Voltage regulator 7805-1 poj niam usb txuas, lossis poj niam rau poj niam usb adapter -1 1n4007 diode-two electrolitic capacitors 10nF 16V-1 ceramic capacitor 22pF (yeem) cov cuab yeej: -Solder hlau thiab cov laug-xaim hluav taws xob strippers -en-20-feeb…
Kauj ruam 1: Pinout, nkag siab txog kev sib txuas
Ua ntej peb yuav tsum nkag siab tias txhua qhov sib txuas tau zoo li cas, thiab dab tsi yog txoj haujlwm ntawm txhua tus pin hauv txhua qhov tivthaiv. Tus pinout ntawm 7805 yog hauv daim duab ntawm no. Thawj tus lej suav nrog prom sab laug mus rau sab xis yog qhov hluav taws xob Hauv. Hauv no koj tuaj yeem txuas txhua qhov hluav taws xob los ntawm 6V (7V hauv qee qhov) rau 12V kom ntseeg tau tias koj muaj 5V hauv Vout tus pin. Tus pin thib ob yog hauv av, thiab tus pin thib peb yog tus uas ib txwm yog 5 Volts. Koj tsuas yog yuav tsum txuas lub hnub ci cell rau Vin thiab hauv av rau hauv av. Tus pinout rau usb kuj yooj yim heev. Yog tias koj saib nws cov tooj liab saib thiab suav los ntawm sab xis mus rau sab laug, thawj tus pin yog 5 Volts, thiab tus lej thib 4 yog hauv av. Kuv yuav upload ib daim duab rau koj kom pom meej dua.
Kauj ruam 2: Schematics
kom paub tseeb tias kuv tsis them roj teeb ntau ntawm kuv lub xov tooj Kuv siv lub ntsuas hluav taws xob (7805). qhov no kom ntseeg tau tias qhov hluav taws xob Kuv yuav tsum them lub roj teeb ib txwm yog 5 volts. Tom qab ntawd kuv txuas lub hnub ci xov tooj mus rau tus tswj hwm hauv thiab usb adapter rau tus tswj hluav taws xob tawm. Txhawm rau kom tau txais qhov hluav taws xob txhua lub sijhawm kuv ntxiv cov electrolitic capacitors 100uF 16V, thiab qhov ntawd yog tiag tiag.
Kauj ruam 3: Npaj Mus
Tsuas yog txuas txhua yam zoo li cov phiaj xwm thiab koj tau npaj mus. Yog tias koj nyiam txoj haujlwm no lossis xav saib qhov no hauv lus Mev, thov nkag mus rau hauv kuv lub vev xaib kom pom ntau cov haujlwm zoo li no.: D
