I am using Arduino motor shield and Arduino UNO to control two 12 volts 990 mA motors.
Last week, the motors were controlled with the shield with no issues.
Now, when I tested the program again the controller is making a continuous sound (beep)
and they motors are not moving.
What could be the issue ?
I connected the motors directly to the battery and they are moving meaning the battery is not empty.
Please advise.
