Electronic Pet Door - Arduino Nano LCD RFID Security Door

arduinocatdoor

Electronic Pet Door, products and first test

 


How can we easily make an electronic project with Arduino to create a cat flap allowing the exit and entry of your cat but not that of the neighbor!
Objects used for this project:
2 colored LEDs.
RFID card reader induction.
1 servo motor.
1 Arduino development board.
1 ProtoShield extension.
2 decks of experimentation.
Resitors, jump cable and USB power cable 1.

Final product online test
