I am trying to piece together the equipment for an industrial project I am working on that uses a Sabertooth DE-05 to control the speed of a DC Motor. In the same project I have a BOT Board II that is only controllling 3 servos. There is a lot of leftover I/O that I would like to put to good use. Could I use one of the servo I/O running 5v as a potentiometer to control the Sabertooth DE-05? Otherwise could I use the BOT Board II to latch on 5v to start the Sabertooth and remove 5v to stop it? I am completely new to Lynxmotion products and robotics in general, but not to basic electronics concepts and programming.
Thanks so much for taking the time to read my post,

You could gut out an R/C servo, removing the motor and electronics, and connecting the center wiper of the pot to the center lead of the servo. Do an A/D read of the pot with the BB II.
(motor could be left in for some drag, if desired).
Thanks very much for the information… especially the drawn out diagram. This will be quite helpful. I am going to look up the SSC-32 to see if it will solve my problem. I will let you all know how it goes.
Also, I went ahead and bought the bot (hahaha) board II and Sabertooth, so once I get it set up, I can run some tests. Dissassembling a Servo probably wont be necessary. Great idea though.
Thanks again you two for the ideas. They drove me down the right path for the solution. I ended up using the bot boards general IO to create a PWM that controlled the sabertooth in analog mode. It is not that fancy and provides no real feedback, but it gets the job done. Next I need to figure out why my hservo commands are not working… but that is going in another post.
