Power Consumption Record system

This system use ADC of Arduino to get the drop of resistor(10ohm), then use UART transmit to PC,

In PC, I programing in Python to receive data from Arduino, then record and calculate power consumption.

System architecture shows below

Arduino transmit 2 bytes every 343us that is a constant time interval,

So I can know the transmit time on Python, according transmit time I can calculate the accurate power on system
