Access Control with Arduino

Project that integrates Arduino, RTC display with I2C, RFID reader and SD card module.

Each RFID card is registered, and is recognized by the reader, freeing access to official and marked the date and time of each employee entrance.

I decided to do this project to help a friend who does not have access control system in your company.

In the future, I want to know the Microsoft Azure platform for sending data to the cloud, eliminating the use of the SD module.
