Good day all.
I am looking at doing some voltage and current monitoring with my Arduino Uno.
The voltage range is 0-15vdc, and 0-5amp.
I know I can monitor the voltage by just using simple voltage divider into the Arduino ADC port.
Regarding monitoring the current I know I can buy current/voltage monitoring ic's that I can interface with the Arduino, but I would like to keep away from that.
So what I would like to know is how do I go about sizing the right current shunt resistor vavlue for a 0-5amp load, so that I can use the Arduino adc port.
Looking in my used parts bin, I have found a bunch of "DALE LVR-3 0R01 1% 3W" Resistors.
Would this be suitable?
Thanks for your time.
Best Regards.
