  • schedule- Time frame Task 1 - 2 hours Design layout for doorbell mechanism including where the elements (camera and button) will be placed withing the weatherproof box and how the simplest connections with be. Also plan where cuts will have to be made to minimise compromising the case 3 - 4 hours Complete the connections from each element to the raspberry pi, the button needs to be securely wired, the camera needs to be connected via USB and USBC cable and the speaker via Bluetooth. 10 hours Configure the program should run. When the button is pushed, a ring to the computer should sound. Optional, the user can access the camera and if needed, speak to the button pusher 3 - 4 hours Implement functioning circuit into the case by measuring and cutting out pieces desired places and gluing down the pi, camera, and speaker. Install button and place seal or glue around cable hole to seal waterproofing. 1 hour Test final product and trouble shoot any problems
