yes, just a bit of fun.
Okay! I have tried as hard as I can to follow along, but you guys with your "bits of fun" are giving me a serious headache now.
This forum really needs a Genius Free Zone
so guys like me can still come out to play safely.
If you fellows don't mind indulging me, please let me restate and summarize what I think is happening, and anyone please tell me where I'm right and explain to me where I'm wrong. Bear in mind that I don't know the full capabilities/purposes of all the goodies that Lynxmotion and BasicMicro provide:
1. The Master provides control signals to position the Slave in a manner somewhat analogous to the way an indoor control rotor used to control an outdoor TV antenna rotator. (Little history lesson there for you young guys.
2. There are many ways matched motor-like combinations can control each other: stepper motors, motor-dynamo, etc. In this case, continuous rotation is ruled out, and reversability is required. So the matched combinations are pairs of servomotors in which one of the servos is modified to act like a potentiometer. This pot servo is in the master.
3. The pot servo modifies an output voltage which becomes the input signal that tells the servo in the slave what to do.
Here's where I start getting shakey, so watch me carefully.
4. The master and the slave can have completely separate power supplies of differing voltages. So to avoid power conflicts, the signal wire between them should probably be isolated somehow, perhaps through an optoisolator.
And now I am completely lost.
5. How does the signal wire connect? Can it go directly to the signal pin on the slave servo? Or can it go to an input pin on an SSC-32? Or must it go first to an input pin on a BotBoard II before going to the servo or to an SSC-32?
6. Where does isolation occur? Do the BBII and/or SSC-32 provide it, or must there be an additional component?
Thanks to all who help. And remember, the fact that some of us don't understand all this immediately does not diminish the lustre of those of you who do.
