Kauj Ruam 2: Tso Tawm Cov Khoom Siv Hluav Taws Xob

Txhawm rau kom Txoj Haujlwm no ua haujlwm, peb yuav tsum txuas tag nrho cov khoom siv hluav taws xob.

Cov ntaub thaiv npog LoRa tuaj yeem tso tau yooj yim. Tsuas yog ua tus pin nrog tus pin ntawm koj Arduino.

Lwm qhov kev sib txuas tau piav qhia hauv kuv cov phiaj xwm Fritzing. Uas tuaj yeem rub tawm ntawm no:

Kauj Ruam 3: Tsim Tus Database

Yuav kom khaws tau txhua qhov kev ua si thiab cov ntaub ntawv ntsuas, kuv tau ua ob peb lub rooj:

Kev ntsuas los ntawm cov ntsuas pom, pom hauv cov ntxaij sensor. Nws muaj qhov siv rau lub ntsuas, tus nqi ntawm kev ntsuas (piv txwv li coördinates: 51.123456; 3.123456) thiab xaiv tus lej game (yog tias muaj kev ua si thaum lub sijhawm ntsuas).

Cov npe neeg uas ua ntawv thiab UID ntawm lawv daim npav cim npe RFID. Xaiv tus neeg saib xyuas thaj tsam ntxiv, tus neeg no tuaj yeem hloov kho qhov kev ua si (piv txwv li tso tseg nws ua ntej lub sijhawm).

Cov ntaub ntawv game (pib thiab sijhawm kawg).

spel_has_speler Kev sib raug zoo ntawm spel thiab speler. Nov yog qhov chaw uas cov players tau muab tso rau hauv qhov kev ua si.

bezit Hauv cov lus no, cov qhab nia tau txais kev cawmdim. Nws suav nrog tus lej game, tus lej player, lub sijhawm nws nyiag lub thawv thiab lub sijhawm nws poob nws (thaum lwm tus nyiag nws lossis thaum qhov kev ua si xaus). Los ntawm kev rho tawm lub sijhawm pib los ntawm lub sijhawm kawg, koj tuaj yeem xam cov qhab nia nws tau txais los ntawm kev ntes ntawd.

Kev xa tawm ntawm cov ntaub ntawv tuaj yeem pom ntawm kuv GitHub (https://github.com/BoussonKarel/CaptureTheBox)

Qhib sql hauv PHPMyAdmin / MySQL Workbench thiab khiav nws. Tam sim no lub database yuav tsum tau ntshuam.

Kauj Ruam 4: Teeb Tus lej ntawm TTN

Kauj Ruam 1: Sau npe rau tus as khauj ntawm TTN thiab tsim daim ntawv thov
