Yav dhau los kuv tau siv qhov ruaj khov 3.3v/5v tswj lub rooj tsav xwm rau kuv daim ntawv qhia zaub mov noj. Txawm li cas los xij, tsis ntev los no kuv tau muaj xwm txheej qhov xwm txheej pib ua rau muaj kev tswj hwm ntau dhau ua rau cov khoom siv sab hauv 5v tswj kom luv Circuit Court, thiab muab cov hluav taws xob ntau dua 12v.. Qhov xwm txheej no tsuas yog kuaj pom thaum cov khoom pib pib kub hnyiab, ouch! Cov no tsis zoo tagnrho rau cov kab hluav taws xob hauv daim phiaj, vim tias lawv TSIS YOG luv luv tiv taus. Yog tias cov kab hluav taws xob tsis raug, lawv tuaj yeem raug puas ntsoog thiab mus rau qhov qhib hluav taws xob lossis tseem phem dua, luv Circuit Court. Thaum sim nrog cov kab hluav taws xob, nws feem ntau tuaj yeem nyuaj rau kev saib xyuas tas li cov khoom siv hluav taws xob thiab tam sim no tau siv. Nws yuav zoo dua yog tias lub hwj chim muab:* Qhia tawm qhov hluav taws xob tso tawm* Qhia tam sim tam sim no* Muaj qhov hloov pauv tau qhov hluav taws xob* Yog luv luv tiv taus kab mob* Muaj qhov hloov pauv ntawm/lub zog hloov pauv* Kev cog lus me me, tsis yog lub rooj zaum saum toj kawg nkaus Qhov no tsis ruaj khov …

Kauj Ruam 1: Tsim

Kuv pom qhov tsim nyog DC-DC kho qhov hluav taws xob muab nrog LCD zaub rau volts/amps thiab rooj plaub, ntawm eBay rau qis dua £ 4: Inpur: 5-23v Tso Tawm: 0-16.5v ntawm 3Avoltage poob: 1 volt Nws muaj qhov loj nyeem tau yooj yim xiav backlit LCD zaub thiab los nyob rau hauv kev cai tsim cov ntaub ntawv perspex nrog nce/nqis kho cov nyees khawm thiab hauv/tawm cov ntsia hlau. Tam sim no qhia rau 2 qhov chaw sib luag (tsawg kawg 10mA). Qhov kawg teeb hluav taws xob kuj tseem khaws cia ntawm lub zog nce. Kuv npaj siv nws nrog 12v cov khoom siv hluav taws xob thiab feem ntau tswj hwm mus rau 3.3v/5v/9v mov. Yog li cas, nws tsis muaj lub zog hloov pauv. Yog li kuv txiav txim siab koom ua ke hloov hluav taws xob sab hauv los ntawm kev tso nws ua ntu nrog cov khoom siv hluav taws xob nkag, thiab teeb tsa nws ntawm rooj plaub.

Kauj Ruam 2: Qhov & Cov Cuab Yeej

Qhov: Kho lub hwj chim LCD module nrog rooj plaub. Hloov me me rau/tawm (thawb hom toggle). Kev Txuas Hluav Taws Xob Qhov hloov kuv siv tau tuaj yeem daws tau txog 1A ntawm 30 volts DC, uas txaus rau kuv xav tau. Yuav los ntawm banggood. Optional: Hlau pwm DC qhov cuab yeej: Drill. Sharp khoom siv tes ua riamSoldering hlau Kub kua nplaum phomDigital multimeter

Kauj ruam 3: Sib dhos

Siv 2 lub xov hlau rau lub toggle switch. Idrilled 2 qhov rau cov xov hlau kom pub los ntawm qhov hloov mus rau ntawm lub vaj huam sib luag sab saum toj. Dhau cov xov hlau hla thiab kub kua nplaum hloov pauv hauv nws txoj haujlwm. Cut txoj kab los ntawm cov khoom siv nkag mus rau lub diode, siv rab riam ntse. Cov kab no pom ntawm cov khoom siv sab ntawm lub rooj tsavxwm. Muaj ob txoj hauv kev nyob ib puag ncig no, txiav ib qho ze tshaj plaws ntawm lub davhlau ya nyob twg zoo tshaj, nyob ze ntawm ntug ntawm pawg thawj coj saib xyuas nws tawg los ntawm kev ua txuas mus xyuas ntawm lub davhlau ya nyob twg thiab sab laug ntawm qhov saum toj no diode (ze ze ntawm pcb). solder ib txoj hlua hlau hloov mus rau lub davhlau ya nyob twg hauv qab PCB, thiab lwm qhov mus rau sab laug ntawm lub diode saum toj no (ze ntawm pcb ntug) Ntsuas qhov hloov pauv ua haujlwm Kuv txuas nrog lub qhov (socket) DC molded mus rau qhov txuas txuas kom yooj yim txuas ntawm kuv sab nraud 12v khoom. Rau qhov tso tawm qhov hluav taws xob, Kuv sib tw ua ke ob khub liab/dub cov tub ntxhais hlau xaim kom yooj yim txuas rau lub rooj sib tham. Lub rooj sib txig sib txuas nrog cov khoom siv 2 lub taub hau ntsia hlau. Koj tuaj yeem ntsuas lub LCD module siv digital multimeter thiab nias sab laug ntawm lub zog. Tom qab ntawd yooj yim kho cov nyees khawm nce/nqis kom txog thaum 5v qhia tawm ntawm lub ntsuas qhov tso tawm. Ua haujlwm tiav!

Kauj Ruam 4: Cov txiaj ntsig

Cov khoom siv hluav taws xob no txias heev! Nws kuj tseem siv tau rau kev sim ua haujlwm nrog qhov sib txawv ntawm qhov hluav taws xob. Piv txwv li koj qhov phiaj xwm zaum kawg tuaj yeem ua haujlwm los ntawm roj teeb lithium nrog cov khoom siv nruab nrab ntawm 3.3 thiab 4.2 volts. Qhov xwm txheej no tuaj yeem sim tau yooj yim. Tsuas yog khaws lub qhov muag ntawm lub vijtsam thiab hloov lub hwj chim hloov tawm. Kuv zoo siab ua qauv!
