Cov lus qhia no yog cov lus qhia ib kauj ruam los ua kom muaj cua nkag mus siv Raspberry Pi. Nov yog txoj haujlwm rau tsev kawm ntawv, Kuv kawm MCT (Media thiab kev sib txuas lus thev naus laus zis) ntawm HOWEST Kortrijk, qhov uas peb yuav tsum tau siv tsawg kawg 3 qhov sib txawv, tus actuator thiab zaub.

Qhov ntsuas qhov ntsuas cua sab nraud thiab sab hauv, qhov av noo thiab feem pua ntawm lub teeb. Cov ntaub ntawv no raug xa mus rau lub chaw khaws ntaub ntawv. Cov txiaj ntsig tau tshwm rau ntawm lub vev xaib me Kuv tau ua qhov twg koj tuaj yeem ntxiv qhov koj nyiam. Sab nraub qaum yog khiav ntawm Raspberry Pi.

Kauj Ruam 1: Cov khoom siv

• Raspberry Pi 3 B+ nrog lub hwj chim thiab SD-daim npav
• 9V roj teeb
• DHT11 av noo thiab ntsuas kub
• 29v qw
• OLED zaub
• Ib lub xov tooj cua kub sensor
• L293D ua
• YWB 3008
• Lub teeb nyob ntawm tus tiv thaiv
• Dhia xov hlau (txiv neej-poj niam thiab txiv neej-txiv neej)
• 4.7k Ohm tus tiv thaiv
• 10 k Ohm resistor
• Breadboard Enclosure
• Multiplex (18mm thiab 3mm)
• Plexiglass (4 hli)
• Ntsia Hlau
• Xim
• Ntoo nplaum
• Laum

Kauj ruam 2: Circuit Court

Nov yog qhov Circuit Court rau kuv qhov project. Nws muaj ntau cov xov hlau tab sis nws tsis nyuaj rau tsim. Nco ntsoov ua kom muaj kev cuam tshuam hauv qab no ntawm koj li Raspberry Pi

• SPI: rau MCP
• I2C: rau OLED zaub

Kuv siv cov tsev qiv ntawv hauv qab no:

• DHT lub tsev qiv ntawv: https://learn.adafruit.com/dht(Nco tseg: Lub ntsuas cua no tsis yog qhov tseeb, yog tias koj xav tau nws yog, Kuv xav kom nrhiav lwm yam.)
• L293D lub tsev qiv ntawv:
• Nruab Adafruit_SSD1306 lub tsev qiv ntawv los ntawm pob khoom
• Nruab Adafruti_DHT lub tsev qiv ntawv los ntawm pob khoom

Kauj ruam 3: Cov ntaub ntawv kaw

Tom qab ua qhov Circuit Court, kuv pib tsim lub thaiv. Kuv xav muab txhua yam tso rau hauv chav ua noj me me. Kuv siv MDF 3mm, 18mm thiab plexiglass 4mm. Kuv tau ua ntau qhov nrog laum kom muab cov xaim hla.

Cov duab kos tau ua ntawm qhov ntsuas ntawm 1: 3 cm thiab 1 lub thawv muaj qhov ntev ntawm 0, 5cm rau kev siv.

Kauj ruam 4: Database

Kuv siv cov ntaub ntawv no rau tus lej kuv txuas hauv cov kauj ruam tom ntej. Nws tau ua nrog MySQL thiab tuav ntawm Raspberry Pi nrog MariaDB.

Kauj ruam 5: Code

Kuv muab txhua txoj cai tso rau hauv ib lub chaw cia khoom github, koj tuaj yeem pom pem hauv ntej-kawg nrog rau sab nraub qaum nyob ntawd. Code: Kuv github repository lossis rub tawm thiab unzipped cov ntaub ntawv kuv upload ntawm no.
