I'm currently working on a project that is a small rover with six wheels (12V gear motor on each wheel) and I need to find a way to stop the motors when they stuck and in stall. I found a 3 channel current sensor called INA3221 and I thought about using it, but I didn't find any instructions so I thought maybe one of you guys may have better solution to my problem.
Here are the specs of my motors:
12V, 60RPM, Gear Box motor, 130N cm torque.
If you guys need more information I will gladly share
But I didn’t see any thing Arduino
Related ( but it may be out there) You could look at Hall effect devices , a small series resistor could be used to sense current , or maybe detect that the wheels are not revolving
If you feed the current to the motor through a 1 ohm resistor (or smaller if the current is high) you can determine the current by measuring the voltage across the resistor. Some motor drivers have that feature included.
Wawa:
Which motor driver are you using.
Maybe your driver chip already has a current sense output.

The motor driver that i'm using is L298N.
Since I have 6 motors, I use 3 drivers.
outsider:
You forgot the most important spec, current draw at stall torque.
When I checked I think the current draw at stall torque was around 300mA on one motor, but I'm not sure since
It was a while ago, I will check and report again.

That's the driver chip.
The chip has the feature of motor current sensing, but has the board designer implemented it...
Post a link to the driver board.
