To decrement the timer. and there should be a buzzer that ring when the timer finish. The clock should work on a built in chargeable battery.

It should just be a passthrough design that only monitors the CC lines for attach detection. I'm needing it to know if both ends are connected and not just 1 end of the cable. I have attached an image of my KiCad schematic of what I currently have using the INA219. However, it may be better to use a FUSB302/HUSB238 that's designed to monitor both CC pins so that it dont have to use 2 INA219's for each of my 6 usb-c input/output connectors. I plan on using a Arduino Pro Micro for the i2c communication to the FUSB302. I will be needing only 1 passthrough example that I can turn into the 6 input/outputs that I am needing. ...
