SmartFreezer yog txoj hauv kev yooj yim los npaj koj lub tub yees. Txoj haujlwm no muaj lub vev xaib uas tau teb zoo yog li nws tuaj yeem siv tau ntawm txhua lub cuab yeej.

Txhua yam ntawm koj cov khoom tau nthuav tawm hauv qhov kev pom zoo. Cov khoom lag luam muaj cov ntaub ntawv hauv qab no:

• Lub Npe
• Icon
• Hnub tsim
• Lub sij hawm tas sij hawm
• Lus tawm ntxiv

Cov khoom tuaj yeem muab ntxiv rau cov npe ntawm peb txoj hauv kev, siv tus kheej, siv tus qauv lossis ntawm tus lej barcode ntawm cov khoom.

Templates yog cov khoom lag luam uas tuaj yeem ntxiv ntxiv thaum xav tau. Yog li koj tsis tas yuav nkag mus rau txhua cov ntsiab lus ntawm cov khoom txhua lub sijhawm koj muab tso rau hauv koj lub tub yees.

Kuj tseem muaj nplooj ntawv ntsuas kub uas qhia txog qhov ntsuas kub tam sim no thiab cia koj hloov nws.

Thiab kawg kuj tseem muaj nplooj ntawv teeb tsa, tab sis qhov no yog nplooj ntawv dag. Tsuas yog cov nplooj ntawv qhia uas qhia tus IP chaw nyob ntawm raspberry pi.

Kauj Ruam 1: Cheeb Tsam

Cov cheebtsam koj xav tau rau txoj haujlwm no yog:

Raspberry Pi 3 B/B+

• Ib lub vijtsam kov
• Barcode scanner
• Kub sensor (ds18b20)
• Lub suab nrov nrov
• 10 k ohm resistor
• 110 ohm tiv thaiv

Yog xav paub ntxaws ntxaws txog tus nqi ntawm kuv qhov project saib:

Kauj ruam 2: Tsim Circuit Court

Txuas txhua yam:

1. Txuas lub barcode scanner mus rau Raspberry Pi siv USB.
2. Cov zaub tseem txuas nrog siv USB tab sis tseem siv hdmi rau Pi.

3. Txuas lub ntsuas kub mus rau gpio pins ntawm Raspberry:

   1. Hlau liab> 3.3V
   2. Dub hlau> GND
   3. Hlau daj> GPIO4
   4. Solder 10k resistor ntawm cov kab liab thiab daj.

4. Txuas lub buzzer mus rau gpio pins:

   1. Tus ncej ntxiv rau 110 ohm resistor thiab los ntawm tus tiv thaiv mus rau GPIO17.
   2. Tus ncej rho tawm mus rau GND.

Kauj Ruam 3: Teeb Kho Raspberry Pi

Txhawm rau pib txuas cov keyboard rau Raspberry Pi thiab txuas lub zog rau pi thiab cov zaub. Koj kuj tseem tuaj yeem siv lwm cov zaub rau theem no zoo li tv lossis lwm yam.

Thawj kauj ruam yog rub tawm cov ntaub ntawv tsim nyog:

wget

Tom ntej unzip cov ntawv:

unzip smartfreezer.zip

Ua kom cov ntaub ntawv teeb tsa ua tiav:

chmod 744 teeb tsa

Pib teeb tsa:

./setup

Tom qab ntawd txhua yam yuav tsum teeb tsa

Kauj Ruam 4: Tsim Kev Tsim Kho

Kuv tus kheej tsis yooj yim heev yog li kuv tsis tsim kho kuv tus kheej tab sis kuv tau pab tsim nws.

Yog li cia koj lub tswv yim ntws thiab tsim qhov xwm txheej tshwj xeeb rau txoj haujlwm no!

Kauj Ruam 5: Xaus

Nov yog qhov haujlwm muaj txiaj ntsig zoo rau cov neeg uas tsis paub dab tsi hauv lawv lub freezer.
