user18805: I need a motor controller for a 24v motor and I want to control it using än Arduino Uno. Suggestions?
The motor needs to run both directions and is going to draw about 5A

user19513: try this Arduino Compatible Mega Motor Shield. Specs:

Low-cost robust H-bridge ''shield'' for Arduino
Provides the ability to control up to 30A of current at up to 28V
Supply voltage: 5V to 28V (24V max battery rating)
Continuous output current: 13A
Have, a look:
