A very brief overview of an electronic lock system that I put in the cabinets The house I'm in had an issues with food going missing so I used an arduino mega, sd card reader, and repurposed an old keypad (was from a dollar store door alarm).
Each resident has a code for the front house door and their respective rooms that is unique to them and their code now also works on this cabinet system. all the electronics hideaway inside the wall of the home office, I'm the only live in resident with access to the office.
