Arduino RFID time clock

Posted on Sunday, April 8th, 2012 in Arduino, project logs, RFID by the machinegeek

FRIC at ivoidwarranties has developed an Arduino addiction. So when his company needed a replacement time clock he wasn’t content to settle for a substandard commercial unit. 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, along with an DS3232 RTC in order to make the project a standalone unit.

FRIC has documented this project’s development in Part 1 and Part 2 of his posts and promises more details. Interesting, practical project. We’d like to see a link to the code/schematic.
