Topic: serial port disappears when a servo is connected (Read 2257 times) previous topic - next topic


plzz help me iam new to arduino ...i wanted to control a servo through serial port .the problem is that when the servo is connected i cant use the com port the following error is coming and the port is working after the servo is removed ....



Most likely your servo is drawing more then the 500ma max that a usb connection allows. Power your servo with an external regulated +5vdc supply or four AA batteries and see if the problem does not go away. Be sure to also make a wire connection from the external ground to the arduino ground.


tanx @retrolefty  i will try it and post the result


thanks again retrolefty  the problem is resolved :D
