# Type of inputs
-### :x: Disabled input(0)
+### :lock: Disabled input(0)
This type of input has to be used if you don't need one of the inputs and want it to be ignored. The ouput will always be 0.
The [skateboard](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Variant-SKATEBOARD) variant for example is only using one input.
-### :arrow_right: Normal pot(1)
+### :level_slider: Normal pot(1)
This type of input will be mapped to a positive ouput(voltage/speed/torque) only.
0----------> INPUT_MAX(1000)
The [hovercar](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Variant-HOVERCAR) variant for example is using such inputs (throttle/brake handles or pedals)
-### :left_right_arrow: Mid-resting pot(2)
+### :joystick: Mid-resting pot(2)
This type of input will be mapped to a positive and negative ouput(voltage/speed/torque) on each side of the resting/middle position.
