Drive from half speed to full speed toggled by a button

[chubchub5577]

We would like to be able to make the bot go from full speed drive (We are using tank drive) then using a button to toggle it into half speed for fine adjustments then hit the button again to go back into full speed. If you have any questions feel free to ask I will answer ASAP. Thanks for any information!

Many teams have used squaring the input to give better low speed response to the sticks. May try and see if that feels right to the driver.

If using xbox controllers there are buttons on the sticks, so you can use those buttons to give finer control, and square the input.

Perhaps you can code a LabVIEW equivalent of this.
