I am very new at this so forgive my lack of knowledge. I've researched beforehand but everything I find doesn't quite make sense.
I'm using the arduino uno starter kit. I set up the circuit shown in project 9 of the starter kit, the motorised pinwheel. Which works fine, my problem is that I attempted to modify the circuit by using the battery and motor from an old electric screwdriver, which is a 3.6v motor powered by essentially 3 AA batteries. Reason for this being that I want to combine the knock knock lock and the motor and gearbox from the screwdriver to open a door on my TV stand.
My problem is that when all hooked up, the mosfet gets hot after 10 - 15 seconds and the motor does not turn, only vibrates (or that's what it feels like)
The mosfet I'm using is that supplied with the starter kit.
I'm sure it's a fairly simple answer but I'm struggling. Any help would be appreciated.
