Arduino motor sheild

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.

Can you post a link to the specs/data of the motor sheild please?
There are many "motor shields" on the market, all different.

Did you disassemble your project and then re-assemble it, and now its giving you problems?

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?

A picture of your project will help also.

Thanks.. Tom.. :slight_smile:
