I'm trying to make project 9.

When I press the switch the motor starts.
When I unpress it, the motors continues running decreasing its speed really slowly. Even if I stop the motor (with a finger), it will start again.
If I unplug the battery the motor stops directly.

So, it seas that the mosfet, when I send LOW to gate, the connectivity between the drain and the soruce, instead of stopping, is decreasing gradually.

Any thoughts on what may be happening?

Thanks.

Hi mateuyabar

What type of MOSFET are you using?  What is its part number?
