Hello World!! this is my first project in instructables web site I hope you enjoy in this project

Step 1: Arduino UNO WiFi

This step i will introducing the arduino uno wifi this board has work like ESP8266 but in the first use you must to config the network in you board

Step 2: Why I Make This Project

In the school student sometime they has go to school late. And i think this problem can be resolve by 'Sing in system'. It can help them not late and they parents can see time to they child go to in the class room past the web page.

Step 3: Curcit

This step I will show you about the Curcit like in the picture

Tool you need:

1 LCD_I2C

2 RFID-RC522

3 DS3132 Time module

4 Arduino UNO WiFi

Curcit

1)LCD_I2C:

SCL->SCL

SDA->SDA

VCC->5V

GND->GND

2) RFID-RC522:

SDA->10

SCK->13

MOSI->11

MISO->12

GND->GND

RST->9

VCC->3.3V

3) DS3132 Time Module

SCL->A4

SDA->A5

VCC->5V

GND->GND

Step 4: Programing

This step to tell you about programing and how to this project work.

Ok if you have a student and go to school and you have RFID card you come at school and input card in the RFID module and go to web server which publish by arduino uno wifi and click sing in and the arduino uno hsa get a number and send it to program write by c# and the program keep this number to save database.

And student'parents can be look time they child go to school at the web page create by java jsp

Step 5: FORMORE INFORMATION

Okay if you want to do this project like me go to my page on Google+ . and you can see this page has a thai language but i promise you I will translate it to English ps code of this project i will upload ti to github soon
