Driving a ride on toy car motor

Hi folks,

As part of a project I'm building I need to create a rotating platform and I recently salvaged a DC motor and its gear train from a ride on toy car, so I thought if it can scoot a child around it should have enough torque for this application. The problem is that I'm not sure how to drive it.

Advice on building a pan/tilt robot arm

 

Hello LMR folks,

I am in need of some advice over a robot project I plan to build. I have a small amount of experience with using an Arduino, soldering and general circuit making, but I've never used motors yet.

What I plan to do is to have a "robot arm" attached to the ceiling with a camera at the end of it. The arm need to be able to rotate the camera around and depending on some conditions tilt it at different angles.
