A Pico Python powered device with mechanical bells.

This is V2 of a project I did a few years ago. The IKEA DEKAD is a pretty package that makes a nice project case and comes with awesome mechanical bells. The Freemometer replaces the clock mechanism with a Servo and adds a couple status LEDs. A microcontroller is added to run the servo, LEDs, and the motor that drives the alarm bells. It is really the alarm bells that make the project.
