Retro Rotary Dial Internet Connected Lock
Category : Electronics Internet of Things
I’ve had this old retro telephone rotary dial lying around for many years, and my son has asked me over those years if we could make an electronic push button combo lock. So after recently teaching him the basics of C programming, we decided it was time to whip up a crazy project at 1am that made use of this old rotary dial instead of a push button keypad. It’s just so satisfying to dial in a number, and hear the wheel whir counter-clockwise after each digit.
