RFID card door lock
BeginnerBuild time 2 hours· You'll learn: Arduino, RFID, I2C displays
A 13.56 MHz RFID reader recognises cards and key tags. The Arduino checks the card's ID against its list, shows a welcome on the 16 × 2 LCD and swings a servo latch open; unknown cards get a buzz. Extend it into an attendance logger for a classroom or lab.
