When you are getting married, the last thing you want to think about is where the guests are seated. While this is normally handled by name tags on the table, hacker and newlywed Gabrielle Martinfortier decided to automate things with an RFID-enabled chart.

In this setup, guests received a mysterious card that they were “encouraged” to keep on them for the big event. When they arrived, they were presented with a seating chart on a large board, with a TFT screen and an RC522 RFID reader. Scanning the reader shows the table were they were located, revealed by an LED assembly that lights it up on the chart. Per the video below, it appears that everything worked smoothly at the event, though the bartender had a backup seating chart in case guests arrived without a card, or if something was to go awry.

The device was prototyped on an Arduino Uno, but since each LED assembly is controlled by an individual output, the project was eventually upgraded to a Mega to accommodate every table. While the system certainly has hacker credentials, the 3’ x 4’ wood canvas used looks quite professional, blending in with what appears to have been a very elegant wedding day!
