This project is about employee time attendance system based on Arduino & RFID. The Ethernet shield is added to make the Ethernet connectivity with Arudino.
The author is addicted to the Arduino things. So when his company needed a replacement of employ time attendance system, he started with Arduino. In the true hacker spirit he designed his own superior time clock system using Arduino and a Stronglink SL018. The SL018 is an RFID reader/writer that interfaces via I2C. Conveniently, it has a ready made Arduino library.
Though initially designed to work in conjunction with a connected PC, he expanded the system to use micro SD card logging and Ethernet connectivity (by adding Arduino Ethernet shield), along with an DS3232 RTC in order to make the project a standalone unit.
Below is the BOM for this system. (very simple)
The author has documented this project’s development in part 1 ~ 4 of his posts. Interesting, practical project. We’d like to see a link to the code/schematic.
