This is an example of remotely unlocking a door lock using RF24L01! The RF24 library is required!
Below is a video of the final result! Sorry, it's in Korean!
- The door lock and Arduino Uno are connected using a relay!
- Connect the nRF24L01 to the Arduino Uno!
- Connect the nRF24L01 and the button to the remote control board!
- Press the button on the remote control board to unlock the door lock!
- The LED turns on depending on the success or failure of the command transmission!
