This project is a prototype smart doorbell system made with an Arduino Uno R3 and various sensors from the ELEGOO Most Complete Starter Kit. This project is being made for a final project for one of my classes here at UVM.
- Setup circuit as shown in schematic
- Download BLE Serial tiny
- When the circuit is connected, run the code in get_rfid_id and copy and paste the tag ID into the acceptedTag variable on line 109 in arduino_doorbell
Optional: Run the code in rename_bluetooth, following the comments to rename your HM-10 Bluetooth Device
