Best Transistor/Mosfet option for a PIC controlled motor help, please ^_^

[Mellowed]

Hi guys, (First Time posting)

I'm trying to build a pic controlled Fish feeder.
So far everything works fine except i'm not sure what my best options would be for controlling the motor.
At the moment it only needs to run in one direction, on off (figured no need for PWM). The motor is a 1.5V-3V motor and i'v been using a power transistor but it seems to not always run.
I' Found a 75N08 Mosfet which i figured could work but would like some input and i'm not to sure if i'v set my circuit up correctly for it.

I'v attached a schematic diagram of the circuit.

Any help or suggestion would be greatly appreciated.

Regards

why not use an N channel logic level mosfet like the IRL540(N) ?

hmm thanks!, never knew such a component existed ^_^

Would i still need to use a resistor between it and the PIC? 

[Simon]

that depends on the frequency, if your turning it on and off as a switch then you could not worry although some people will tell you to. You should have a resistor in parallel with the gate from gate to source

I've just Googled for the datasheet for the 75N08 and it should be fine with a V_GS of 5V.

How much current does the motor use?

[Mellowed]

Well it say's 0.3Amps at No Load and 1.05Amps @ MAX Eff.

Do you rate the layout i'm using in the schematic for the motor is correct, and should i add a Diode over the motor's ports? (I'v never worked with motors before)

[Zero999]

Yes, a diode is good practise, although it's very unlikely a 3V motor is going to generate enough back-EMF to kill a 75V MOSFET.

The current is low and well within the capabilities of the MOSFET.

How are you assembling this? Have you made a proper PCB or are you just using a breadboard?

[Mellowed]

It was originally made on Veroboard but i'll be making a PCB tomorrow using the Mosfet and begin testing.

Thanks for the help!
