http://ubuntuforums.org – Hi all I want to first say I have no programming experience at all. Goal, I have a need to remotely open/close large doors, horse barn. I am going to be using several Dual H-bridge motor(capable of 2 doors each) controllers with actuator arms operating in push/pull capable of moving these doors. I would also like to add 2 switchable video streams A/B to see this happen. The motor controllers come in both USB and Serial models. I am currently trying to get sample source from the manufacture???(long wait). What I would love to be able to do is control these devices with Linux pc/web server setu (Hardware)
