How to wire Digital Inputs and Outputs and Analog Inputs?

I'd use it as a SPST (single pull single throw) switch, because you're just looking to alternate between on and off. This means wiring one side (the 'on' side) to a signal pin of a DIO port. The middle of the switch should be wired to ground.

A potentiometer is a variable resistor. Here is a resource on how to wire a potentiometer. Wire the output wire to the signal pin on the RoboRIO.

For the Switch, the Signal wire will either be connected to Ground (0) or + (1).

For the Pot, the Signal wire will read the distance the pot is rotated.

You will want to adopt a convention on which side is Ground vs +.

I believe the Ports on the Robo Rio are: Ground, +, Signal. With + always in the middle, you don't damage your equipment if you accidentally plug in the connector backwards.

BTW: An easier way to control Autonomous is the Smart Dashboard. Put a field on the screen that the Driver can change. Read the value at the beginning of Autonomous.

Thank you both for your help!
