What motor shield do i need if i want to run up to 4 dc motors, 4 servos.
Please reply with product link from ebay.
for arduino uno.
I'm a big fan of this controller: http://www.robotgear.com.au/Product.aspx/Details/555
It doesn't support servo control but that can easily be done from Arduino's PWM pins.
That's a great controller board. I've talked to the designer and I'm planning to source it on YourDuino.com
