So I need to control a 12 volt servo using an outside power source. I'm assuming I need an H-bridge to handle the power but I can't wrap my head around the wiring specifically the signal wire. I have standard Pololu H-bridges (see below). I've worked with H-bridges and EZ before.
If my assumption is wrong could it be as easy as wiring my servo to my 12 volt power source (with a common ground to the EZ) but use a fuse (for protection) and then use a signal wire to my EZ for control? I've seen postings here that seem to say that. The action is to raise and lower a robot head. It will require 12 volts.
Any advice is always welcome.
Thanks,
Daniel
If it is stiff/stuck when no power is applied then I assume it's seized for some reason (12v may be different, I've not used 12v servos yet, so check with others or take their word over mine if they say I'm wrong).
If that's the case, open it up and check the gears inside to make sure they are all aligned nicely. I had a few Tower Pro MG90s which were stuck and needed to be opened up and reassembled before they wanted to work.
Thanks Rich. You've bee a tremendous help as always.

I had one explode on me once. It was like a shotgun. It went through the ceiling. I was seeing if you could charge an Alkaline Energizer. But, it was a regular one, not a re-chargeable one.
I was very lucky.
