Actually, you can use more than one h-bridge, you just have to use scripts to control the second one. It's a matter of turning on and off ports. There's an example in the EZ-Cloud somewhere.

Check my tutorial on H-Bridges. It explains how they work. You can use this to have more than 1 H-Bridge.

H-Bridge Project from the cloud with some useful info for you.

Multi H-Bridge project which explains how you use more than 1 H-Bridge in a project.

There are topics which go along side those two project files however since they were not my topics I am unable to find them quickly. Have a search for multi h-bridge and I'm sure they will be somewhere.

@Daniel, How are you planning to animate and move your B9? I have mine running totally on scripts. I don't have a lot of personality or reaction scripts set up yet, only basic functions like waist, hip, radar, ears and bubble movements activated by voice. Also, I've got the personality generator installed with a few basic movements that gives him some appearance of stand alone life. However if you plan to move him like a puppet you'll need to set up an external controller like a Wii or an RC controller. I haven't looked into either or how to do it or use them but I do know it's doable through ARC and will also require using scripts. This is something I plan to add later though.

Hi Dave I have no scripting experience at all but would like to get into it. I'm still fumbling with basic connections and settings. As you know the H-Bridge power was finally resolved. This is for my waist control. I still need H-Bridge functionality for my soil actuator, radar section and bubble lifter. I'll try Rich's tutorials. I currently control the board via my laptop.
