Arduino LiPo Capacity Tester v3

I had many requests to enhance this project and this is the result:

• New Menu system
• Multiple cell LiPo packs up to 4S (use a larger heat sink on the FET)
• Interval Logging from 0 to 60 secs in CSV format via the USB UART port
• Arduino controlled current source
• settable Battery stop voltage
• settable Battery load current
• settable logging interval time
• All settings saved in EEPROM

The new schematic:

And the new sketch:
