What methods can be used to detect the current drawn by a 12V 5A motor? (This is so that I can tell whether there is full load, no load in the system) I would like to be able to get some sort of voltage output which corresponds to the current drawn and feed it into the ADC of a PIC.
From my searches, I saw some mosfet drivers with current sensing...but they seem to just shut off the output when it's above a certain current level.....they don't generate an output that I could use to feed into a microcontroller. Am I not searching for the right component?
Could somehow measure the voltage on both the + and - sides of the motor, and somehow get a current out of it?
I am out of ideas..........
