I've been around robotics and controls all my life but the gray hair is getting ahead of the gray matter. I know there is an h bridge joystick controller out there at Radio Shack or somewhere... I want to steer a wire controlled device left and right through a 9.5 volt geared motor and do it by reversing polarity and running through a pot. Is a device such as this available overnight from anybody?
What I have in my hands is an older Radio Shack RC car and we have lost the transmitter so I need to fake a servo type control to the steering and drive motor of the toy.
