Cov cuab yeej xav tau

Laum

Peb yuav pib yooj yim nrog lub npov saum toj. Nov yog lub npov uas koj tso arduino thiab raspberry pi.

ps: Kuv pom zoo kom muaj rooj plaub rau koj arduino thiab raspberry yog li koj yuav tsis ua rau lawv puas tsuaj

1. Coj koj tus Pi thiab arduino tawm ntawm lawv rooj plaub
2. Muab ob rooj plaub tso rau hauv tib lub ces kaum ntawm lub npov
3. Laum 4 qhov hla qhov rooj thiab lub thawv, nco ntsoov tias lawv yuav xav tau kom haum rau cov ntsia hlau m4
4. Muab cov ntsia hlau m4 ntsaws rau hauv lub qhov thiab kaw lawv nrog cov ntsia hlau haum

5. Thaum kawg koj yuav tsum ua lub khob cij nplaum rau ntawm lub thawv qhov no tuaj yeem ua tiav hauv 2 txoj hauv kev:

   1. yog tias koj muaj lub hauv paus hlau, koj tuaj yeem nqa cov hlau hlau thiab laum 4 qhov hauv cov hlau kom koj tuaj yeem siv cov ntsia hlau
   2. tshem cov ntawv nplaum tom qab thiab lo rau ntawm lub npov

Kauj ruam 3: Cov laug cam

Qhov yuav tsum tau ua:

• 2x lis led
• 4x load cov
• coj
• ultra siab sonic sensor
• 2 x 4m utp-kab

• Thaum tshav kub kub ntsws tubing

Cov cuab yeej xav tau:

cam khwb cia hlau

Koj tuaj yeem yuav luag tsim cov kab hluav taws xob tab sis ua ntej koj yuav tsum tau muab cov khoom sib txuas txuas rau utp-cable yog li koj muaj cov kab hluav taws xob uas mus txog rau saum. Nco ntsoov khaws ib daim ntawv nrog cov xim xim;

Ib qho luv luv ntawm yuav ua li cas txhawm rau: Yuav ua li cas txhawm rau hauv 5 cov kauj ruam yooj yim

1. Nqa cov 2 utp-cables thiab txiav lawv ib nrab
2. Nqa 2 loadcells thiab muab cov hlua txuas txuas, 2 zaug
3. Nqa cov kab ntawv coj mus thiab muab lawv txuas rau ib daim kab xev
4. Nqa cov coj thiab ultra-sonic sensor thiab muab nws txuas rau ib daim ntawm cable

Kauj ruam 4: Circuit Court

sau ntawv:

txuas 2 kab ntawv coj mus rau lub hwj chim

txuas arduino nrog pi los ntawm usb

txuas mcr012 barcode nrog usb rau pi

Kauj ruam 5: Mysql

forward engineer no schema li thiab koj muaj koj cov database al teeb tsa

xa cov ntawv no mus rau hauv cov ntaub ntawv pov tseg qhib cov ntaub ntawv pov tseg thiab luam cov cai

Kauj Ruam 6: Nruab Koj Raspberry Pi

thawj nruab raspian ncab: Raspbian ncab

tom qab ntawd siv cov lus txib hauv qab no teev hauv https://github.com/NMCT-S2-Project-I/Project-I readme file

koj tshem tag nrho cov ntaub ntawv project1 los ntawm kev siv

rm -r project1

yog tias koj tau ua qhov no ntawm koj tus pi koj tuaj yeem clone tis repo:

git clone

mus rau maria db thiab dhau los cov cai peb muaj los ntawm cov ntaub ntawv pov tseg
