Help with 2 speed dc motor

I wanna run a dc motor 2 speeds and off , hi low off, manually switching between two speeds with spdt switch. How do use the Arduino to do this?

Have Arduino control a simple relay.
(forum might some extra characters on the beginning and end of the link)

I would use PWM to achieve the two speeds . Drive a transistor from an analog output to switch the motor.

Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.,148850.0.html .

A spdt switch only has two positions, how do you aim to get two directions and OFF.
The spdt switch will have to have a centre OFF position.

Can you post a link to specs/data of the motor please?

Can you tell us your electronics, programming, arduino, hardware experience?

Thanks... Tom... :slight_smile:

A single pole, double throw, center off switch and a resistor will easily accomplish that. Why post on an Arduino forum????
