Programable motor control

Projects General Guidance

Hello,
Im building a B9 lost in space robot that I would like to do some small animations or movements. The main torso has a 12vdc wiper motor that I'd like to make turn clockwise and counter clockwise so the torso will turn left, right, stop centered, etc.

Need to know what boards I need to buy.
Also, does the control board need to be always conected to computer or can it be stand alone once programed?

Thanks

Yup! Just connect a battery (7-12V) across the Vin and GND pins.

What type of wiper motor? Is it a DC motor? Do you have a link to a manual or manufacturer's website?

12 dc 1 to 2amps tops

Not nearly enough detail. Again, is it a DC motor? Where is the datasheet?

Yes it is a DC motor.
12 volts DC
1 amp

Cool, in that case you will need an H-bridge driver. This one can handle two DC motors. There are many tutorials online on how to use an H-bridge driver.

You will also need an Arduino. You probably can get away with an Uno or Nano (depending on your size requirement).

Are there any other actuators or sensors other than the wiper motor?

Here is a pic of the motor. It drives a round ring with bearings and is very smooth. Problem is its so smooth that it travels 2 to 3 inches after power is removed. Are there position sensors that can tie into the nano or uno? Should I replace the wiper motor with a DC motor with an encoder?
