Using servo tester to control esc project help please
Hi, I'm trying to directly control an esc and motor, using a tester. Supplying 5v, everything's good, I can adjust signal to esc.
But what I would like to do, is use the tester to set the gain of the esc, and use another doo-dad as the control.
This is all going in a power wheels type thing. Ill use the tester as a governor, or master adjustment.
It's all worked out except the Doo-dad that will be for input, or an actual throttle .
Can I use another rheostat to vary the input, no, because that would vary my 5v, right??
Any ideas

The usual servo tester can generate a control signal for one channel. This is assumed to be the throttle signal when the pulse train signal is connected to an ESC.
There are other ways, such as using one of the Raspberry Pi micro computers and a "servo hat", and/or a "Hat that has both servo control outputs and motor drive outputs. I'm not sure what you mean by gain, since that is usually a function of a gyro.
The ESC governor mode is intended for heli use, and sets a desired rpm. Other than throttle control, most ESC settings are made via programming before use, not during it.
