Re: Controlling motor speed with joystick scroll

- read the value of that axis (Axis 3 I think)
- convert it to a number between 0 and 1 (y=mx+b, yay algebra)
- Multiply your other joystick inputs by this number (or your motor outputs)

It may not be useful to have the bottom of the throttle act as 0. Maybe make it 20% (0.2 to 1 is now the output of y=mx+b)

let's look at how this works. At full throttle, and max joystick input, the motor will get (joystick * throttle) = (1 * 1) = 1
If you bring the throttle back to 50% (0.5), then the motor gets (1 * 0.5) = 0.5, which is half speed.
