So I want to monitor the current drawn from a DC motor.
This is the circuit I had in mind: https://www.dropbox.com/sh/etny3sgyzmgrn9e/HMYVGX15Rm
This way, the current would be (aprox.):
int current = (2 * analogRead(A0)) / 3;
However, I’m fairly sure this will blow the 3 Ohm resistor in seconds. So I am wondering wether there’s a better way to safely measure the current?
