Runtime Counter v. 2.0

Uptime counter v 2.0

This is a remake of B-labz Runtime counter v1.0 witch was made for use with FM25L16B Fram chip.

The purpose of this project is to make a Runtime counter for your machines like a 3D-printer or Laser module on a CNC machine or whatever kind of working time you wish to count and save. The power comes from a 6-24V pin of one of the machines, this is converted by the mini 360 stepdown buck converter to 5.5V for the microcontroller (connect at RAW pin) , other components are powered by the VCC pin of the Pro Mini. The advantage of the Fram is that it keeps the saved data even when there is no power to it. And will do this for about 10 billions times. When the power returns it starts where it stopped before, so no loss of time even by a power failure.


What is changed:
- The Fram FM25L16B-GTR is replaced by an Adafruit breakout board with a
MB85RC256V chip. This requires a new adapted Arduino code.
- The wiring is now placed on a secondary print that will
