Hall sensor overload and failure What can I do to fix this??
I am using an arduino nano, TB6612FNG and Hall effect sensor to turn on and off two motors.The entire system works just fine the first 3-5 times it is turned on and off. But eventually the hall effect sensor indicator LED turns on and stays on regardless if there is a magnetic field or not. under normal operations the led turns on when the sensor is near a magnetic field but remains off when it is away from the field.
What is happening to cause the hall sensor to go bad?
I don’t understand why there is a failure. The hall sensor is connected to the +5V, D2, and GRND of the arduino board. I amusing a single power source for both the arduino and TB6612FNG
TB6612FNG and Arduino connections are shown in this picture.
