Hi there

You are doing it absolutely right by measuring the voltage drop across a low value resistor. Now this value will help you measure current using ohm's law:

V=I*R; here, R and V are known to us thus, I can be easily calculated. Make sure to conver the ADC value you get back to its voltage reading by some mathematical operation and then use this V to calculate I.

Hope this helps :)
