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 (have called their customer service (ha, ha) clerks and got nowhere)... I want to steer a wire controlled device left and right through two 9.5 volt geared motors 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.
All I want to do is buy a joystick from somebody, hook up the four wires, and start testing some concepts. These are really small motors and really rev up with any kind of voltage.
