5Records each time a USB port is powered on/off and logs the data for 365 days before it resets automatically.
6
7Press the SELECT button to switch between total on/off and total time. 
8Press the LEFT button to reset the program. 
9
10Use this project to log usage times for any device that has an on/off USB port (wi-fi router, 3D printer, computer, etc.).
