FF Motor + LED: Diagram and Resistor question

[betocas]

Hello,

I am working on my first Saber and I am thinking of adding a force feedback motor, connected to the PC board and a AV switch to turn it on or off as required.

Motor: Cell phone moto razr, I believe it runs at 100mA and its 2V.. not 100% sure but this should be safe (I hope)
AV Switch: Green dot LED. fv: 3.3V @ 20mA
3 rebel star: GGW

I would like to know from the forum experts if this diagram is correct and it meets the Resistance required to drive the motor.

Thank you !!!

Diagram looks fine to me. I'd highly recommend using a potentiometer for the vibration motor, and then measure the resistance once you tweak it to your liking.
