Kuv nquag ntsib qhov xwm txheej thaum kuv xav sim lub cav, qee zaum rau kuv cov phiaj xwm, qee zaum tsuas yog pom tias nws ua haujlwm. Qhov kev daws teeb meem yooj yim tshaj plaws tsuas yog txuas nws rau roj teeb lossis qee yam khoom siv hluav taws xob thiab qhov ua tau zoo tab sis ua li cas yog tias koj xav tswj lub cav nrawm piv txwv li los ntawm PWM? Koj yuav tsum siv Arduino nrog lub cav tswj, txuas txhua qhov ntawd, ua haujlwm nws thiab tom qab ntawd koj tuaj yeem siv nws, tab sis qhov ntawd yog haujlwm ntau. Yuav ua li cas yog tias muaj kev daws teeb meem yooj yim dua rau qhov ntawd. Yog li kuv pib xav yog tias kuv tuaj yeem siv lwm yam tom qab ntawd microcontroller los tsim PWM teeb liab, thiab kuv xav txog lub ntiaj teb nrov tshaj plaws kev sib xyaw ua ke (IC) 555 lub sijhawm. Kuv twb tau ua ob peb yam nrog 555 timer zoo li kuv lub tshuab tsis siv, yog li kuv xav tias nws tseem tuaj yeem siv los tsim 555 PWM lub cev muaj zog tswj. Tom qab tshawb fawb nrawm hauv is taws nem kuv pom yuav ua li cas thiaj tsim tau cov xwm txheej zoo li no, nws nyuaj me ntsis vim tias nws tsis yog tus qauv teeb tsa ntawm 555 timer. Ua tsaug rau txoj haujlwm me me no kuv tuaj yeem sim kuv lub cav thiab tsim cov phiaj xwm tshiab ntawm kev mus txhua qhov chaw kuv nyob. Yog li koj puas tau npaj saib seb kuv ua nws li cas? Cia peb dhia mus rau nws!
Sau ntawv ceev los ntawm tus neeg txhawb nqa ntawm txoj haujlwm no:
JLCPCB 10 cov laug cam rau $ 2:
Kauj Ruam 1: Qhov Chaw
Txog qhov haujlwm no koj yuav xav tau ob peb yam xwb, koj tuaj yeem yuav lawv hauv khw hauv online lossis hauv online, ntawm no yog cov txuas mus rau banggood, koj tuaj yeem yuav lawv tiag tiag. Feem ntau ntawm cov kev txuas yog qhov loj dua ntawm cov ntsiab lus tab sis koj yuav pom qhov siv rau lawv hauv cov phiaj xwm yav tom ntej.
- 555 hnub tim
- IRFZ44N MOSFET
- 10 k potentiometer
- Diodes
- 5mm ntsia hlau davhlau ya nyob twg
- DC lub qhov (socket)
- 1,2k tus tiv thaiv
- 10 nF capacitors x2
Kauj Ruam 2: Schematic, PCB thiab Breadboard
Saum toj no koj tuaj yeem pom cov txheej txheem ntawm kab lus no yog tias koj xav txuas qhov ntawd ntawm lub khob cij. Yog tias koj xav ua PCBs koj tseem tuaj yeem pom muaj. ZIP nrog txhua cov ntaub ntawv suav nrog schematic, txheej txheem PCB thiab cov ntaub ntawv gerbel. PCB no tau tsim los hauv KiCAD - software dawb rau tsim PCBs. Yog tias koj xav yuav PCB rau txoj haujlwm no koj tuaj yeem tshawb xyuas kuv lub khw Tindie, muaj PCB rau txoj haujlwm no thiab ob peb lwm PCBs rau kuv cov phiaj xwm. Nov yog qhov txuas rau kuv lub khw:
Kauj ruam 3: Soldering
Tsis muaj ntau yam ntawm cov khoom siv los txhuam, txhua tus ntawm lawv yog THT yog li txoj haujlwm no yog pib ua tus phooj ywg, zoo tshaj yog tias koj xav kawm soldering. Tsuas yog pib nrog cov khoom me tshaj plaws thiab txiav tawm ob txhais ceg ntawm lawv yog tias lawv ntev dhau lawm ces txav mus rau cov khoom loj thiab ntxiv rau. Soldering yuav tsum tsis txhob siv sijhawm ntau tshaj 20 feeb. Ceev faj thaum siv cov hlau txuas, nws kub heev, koj tsis xav kov nws.
Kauj Ruam 4: Txuas Lub Cev
Thaum ua tiav qhov ua tiav koj tuaj yeem txuas lub cav mus rau lub hau ntswj ntawm PCB. Yog tias koj tsis muaj lub cev muaj zog nrog cov xov hlau koj yuav tsum txuas ob lub xov hlau rau nws cov khoom sib txuas thiab tom qab ntawd ntswj lwm qhov kawg ntawm cov xov hlau mus rau lub dav hlau ntsia hlau. Siv lub hau ntswj ncaj rau qhov ntawd thiab ua siab mos siab muag nws yooj yim los rhuav cov khoom me me.
Kauj Ruam 5: Yuav Ua Li Cas Fais Fab?
Qhov zoo tshaj ntawm 555 timer yog tias nws tuaj yeem siv hluav taws xob los ntawm 4, 5V txog 16V. Rau cov tshuab loj dua Kuv tab tom siv 12V lub zog xa khoom nrog DC jack (tus qauv DC nkaus, zoo ib yam uas tau siv hauv Arduino UNO), koj tuaj yeem siv qhov me me thiab loj dua qhov hluav taws xob hauv qhov no, tab sis nco ntsoov txog qhov ntsuas hluav taws xob ntawm koj lub cav. Yog tias kuv yuav tsum muaj lub zog me dua kuv siv lub roj teeb lossis kuv lub chaw tso khoom siv hluav taws xob hauv lub lab.
Kauj Ruam 6: Ua Si Nrog Nws
Kauj ruam kawg yog qhov zoo tshaj plaws! Tsuas yog muaj kev lom zem nrog koj txoj haujlwm tshiab:) Kuv vam tias nws muab kev lom zem rau koj thiab yuav muaj txiaj ntsig zoo rau koj. Kuv yuav twv yuav raug siv nws ua cov cuab yeej hauv kuv lub rooj cob qhia. Tsis txhob hnov qab tawm lus tawm hauv qab no thiab yog tias koj nyiam kuv qhov project. Yog tias koj yuav tsim ib qho, qhia nws hauv social media thiab tag kuv! Ua tsaug rau kev nyeem:)
