I must be using the wrong transistor for a 12 volt dc motor because it is heating up.
What kind of numbers should I have on a transistor?
How much current does it draw at 12V?
Are you sure it gets enough current at the base ?
I have the RFP12N10L mosfet but I am encountering a problem. It is staying constantly on. I am wiring it like the first schematic on this page: http://www.thebox.myzen.co.uk/Workshop/Motors_1.html
