Electronics novice here :-)
I'm attempting to connect a two wire servo (need more torque) to EZ. Is this possible?
Thanks,
D.Scott
It sounds like what you have is a DC motor, not a servo. A servo needs three wires, ground and positive to supply power, and a signal wire to get the information it needs to turn in which direction, and how far.
With a DC motor (which I suspect you have), you will need a motor controller or H-Bridge. This allows the motor to go in either forwards or reverse directions, and controls the speed (if the motor controller or H-Bridge has a speed control option). This connects to the EZ-B digital pins and the two motor wires connects to the two motor output on the motor controller. Below is a very good tutorial a member wrote which explaines what a H-Bridge does and how to connect it.

I've worked with H-Bridges so that's not a problem.
Thanks,

Like the others asked, post a pic if you can, and let's see what you've got.
There are 3 wires. Last year I had separated them, installed the servo in it's bracket, and the third wire got tucked out of sight. Lesson learned. Start a step, finish a step.
Thanks everyone,
Daniel
