Tiny circuit to measure amps? Answered
I am going to use a ATTiny43U to obtain the voltage of a 2vdc solar battery, via self powering (0.8-5.5VDC).
Using ohms law I know I can obtain the amps as I will have the voltage and a resistor.
I want to know what resistor to use?
I will feed the amps result back into the ATTiny43U as well as the temperature from another sensor.
Can someone please advise me what tiny circuit I can use to get the amps as I do not know what size resistor to use?
The operating voltage should be between 1.55 and 2.67 vdc give or take a bit.
Thanks and kind regards,
