Nyob zoo cov!

Peb yog pab pawg ntawm cov tub ntxhais kawm hauv University of Málaga (UMA). Txoj haujlwm no yog ib feem ntawm qhov kev kawm 'Creative Electronics', BEng Electronic Engineering 4th year module ntawm UMA, Tsev Kawm Ntawv Kev Sib Txuas Lus (www.etsit.uma.es).

Peb tes num muaj lub teeb ci. Cov ncauj lus kom ntxaws txog cov khoom siv thiab cov txheej txheem ua raws yuav piav qhia hauv cov theem hauv qab no.

Kauj ruam 1: Kev npaj

Cheebtsam siv:

• Resistors (50Ω thiab 10kΩ)
• Potentiometer 10 kΩ
• Lub hwj chim transistor BDX
• SMD coj 50W
• Coj tsav tsheb (240Vac - 50Vdc)

Peb yuav SMD coj nrog nws tus tsav tsheb hla Amazon (ntawm no).

AB 328 p

Peb yuav xav tau ob lub Arduino cov laug cam (ib ntawm lawv tshem tau microcontroller)

• Pre-drilled Prototype PCB
• DC-DC Buck Converter (LM2596)
• Heatsink thiab thermal paste [yeem]

Ntawm cov duab nyob rau sab saum toj ntawm cov kauj ruam no muaj cov khoom siv uas nws tsis siv rau ntawm thawj lub teeb ntawm lub teeb. Cov khoom siv no yog tus ntsuas qhov ntsuas, peb tab tom npaj yuav suav nrog nws ntawm cov qauv yav tom ntej los tswj kev ntsais ntawm lub teeb nrog kev txav ntawm tes tsis txhob tig lub hwj chim.

Kauj Ruam 2: Schematics & Piav Qhia

Peb tau xaiv BDX transistor vim tias qhov siab DC tam sim no tau txais txiaj ntsig (beta) vim tias peb yuav tsum tswj qhov kev txaus siab thiab txiav tawm lub xeev ntawm transistor tsuas yog nrog lub microcontroller tam sim no (tus neeg tso tawm-emitter tam sim no tuaj yeem mus txog qhov tseem ceeb ntawm 1A).

Peb tes num tau tsim los tswj lub Circuit Court ntawm qhov ntsuas hluav taws xob siab nrog lub microcontroller uas muab cov txiaj ntsig tam sim no qis los ntawm cov txiaj ntsig digital.

Peb tau tso DC-DC tus txo qis (siv qhov tso tawm ntawm AC-DC hloov pauv) rau lub zog ntawm lub microcontroller. Txhawm rau tswj lub luag haujlwm ntawm PWM (uas tswj lub ntsais ntawm lub teeb) peb tau siv lub hwj chim ntsuas hluav taws xob txuas nrog lub microcontroller.

Kauj ruam 3: Codding thiab Uploading Code

Txhawm rau upload cov cai rau hauv lub microcontroller, koj tuaj yeem ua raws cov kauj ruam tom ntej: (los ntawm cov nom arduino webpage)

• Rub tawm cov kho vajtse teeb tsa archive (ntawm no).
• Tsim daim nplaub tshev npe hu ua "kho vajtse" hauv koj phau ntawv Arduino sketchbook.
• Tsiv lub nplaub tshev uas rub tawm ua ntej mus rau "kho vajtse" nplaub tshev.
• Rov pib dua Arduino software.
• Thaum koj rov ua haujlwm dua, koj yuav tsum pom "ATMega 328 ntawm lub khob cij (8MHz lub moos sab hauv)" hauv Cov Cuab Yeej> Ntawv qhia zaub mov.

• Hlawv lub bootloader (koj tsuas yog yuav tsum tau hlawv lub bootloader ib zaug).

  • Xaiv lub rooj tsavxwm thiab chaw nres nkoj txuas los ntawm cov cuab yeej ntawv qhia zaub mov.
  • Hlau txuas rau Arduino board thiab microcontroller zoo li no.
  • Xaiv ATMega 328 ntawm lub khob cij (8MHz lub moos sab hauv) los ntawm Cov Cuab Yeej> Pawg Thawj Coj.
  • Xaiv Arduino ua ISP los ntawm Cov Cuab Yeej> Programmer.
  • Khiav Cov Cuab Yeej> Hlawv Bootloader.

• Xa cov cai: ib zaug koj lub ATMega 328p muaj Arduino bootloader, koj tuaj yeem tso cov program.

  • Tshem lub microcontroller los ntawm Arduino board.
  • Hlau txuas rau Arduino board thiab microcontroller raws li qhia hauv daim duab tom ntej.
  • Xaiv "ATMega 328 ntawm lub khob cij (8MHz lub moos sab hauv)" los ntawm Cov Cuab Yeej> Pawg ntawv qhia zaub mov
  • Upload li qub.

Kauj Ruam 4: Cia Solder Qhov

1. Peb pib soldering transistor thiab resistors.
2. Qhia cov microcontroller hauv pre-drilled PCB thiab txiav cov seem ntawm txoj kab.
3. Cia peb siv lub microcontroller solder.
4. Solder lub potentiometer ze rau cov lus sib piv ntawm microcontroller. Ntxiv cov xov hlau uas tsim nyog tso rau DC-DC reductor module.
5. Solder DC-DC los ntawm lwm sab xub ntiag ntawm PCB.
6. Coj tus SMD coj (nws yog qhov xav tau tso lub rhaub dej kub, peb tau rov siv ib qho ntawm lub tshuab luam ntawv 3D).
7. Solder cov xov hlau uas txuas +Vcc thiab Av (GND).
8. Thaum txhua qhov ntawm qhov muag tau muag lawm, peb tau txiav txim siab tso tag nrho cov kab ke rau hauv qhov qub disco teeb kom cov qauv tsim tseem me me.
9. Tsis txhob hnov qab muab cov laug coj mus rau Vcc thiab lub transistor (peb tau siv lub tshuab txuas hluav taws xob). Nco ntsoov txhawm rau txuas qhov txuas ntawm DC-DC hloov pauv (them sai sai rau cov lej).

Qee qhov kev pom zoo:

• Peb tau txuas cov xov hlau los ntawm Led tsav tsheb kom tau txais kev nplij siab rau nws siv. Qhov kawg ntawm cov xov tooj tooj liab tau muab khi thiab peb tau txuas ob qho kawg. Txhawm rau kom tau txais txiaj ntsig zoo dua thiab zam kev siv luv luv, peb tau siv cov ntawv sov ua kom sov.
• Peb tau ua ob lub qhov nyob rau hauv lub teeb disco kom peb tuaj yeem tau txais cov xov hlau tawm thiab tswj lub zog zoo dua.
