Motors and GPIO Port Choice!

Tue Mar 05, 2013 6:47 pm

Hey All,
I am planning on making a remote control robot with a webcam, it will be controlled remotely and will run on battery power. I need to have two motors running at the same time and they need to go backwards and forwards in order for the robot to be able to turn. I was wondering what motors you would recommend and also what GPIO ports I can use to power the motors effectively.
Thanks in advanced.

Get a https://www.sparkfun.com/products/10825 magician chassis or similar.

Search for a good deal where you live.

You'll need 4 gpios, 2 per motor. There are 8 undedicated gpios on the Pi. Ignore the gpios for now. That part is simple.

Thank You,
That has cleared up a few things, do you know of anywhere I may find the code as I am not very good at python coding, I would like arrow keys to control the motors.
