Good day all.
As per the title name, I am looking to measure current with microcontroller.
My basic understanding of how to measure current with microcontroller, is that you use a shunt resistor in line of the load, and measure the voltage across the shunt.
Most of the shunt resistors I have seen on eBay at 75mv at max current.
Now the question is how would I use one of the 75mv shunt resistors so that I can measure current both ways (-10A to +10A) with microcontroller?
Thanks for time.
Best Regards.
