The Joystick Mixer Node is a single-purpose node that takes x and y axis signals, ostensibly from a [[Joystick Node|Joystick Node]] and mixes them to generate left/right [[wikipedia:Differential_wheeled_robot|differential drive]] motor drive signals that can be passed to [[IO Config Editor#IO Units|H-Bridge IO Units]].

Joystick Mixer Nodes were introduced in [[Firmware Releases|firmware version]] 2.1 along with all basic nodes. It has no configurable settings.

==Inputs==
Joystick Mixer Nodes have two input ports: '''xaxis''' and '''yaxis''', which - just as their counter parts in the [[Joystick Node]]'s output ports - represent a position between (0, 0) and (1, 1) on a dual-axis joystick, where (0.5, 0.5) is the central position - the ''neutral position'' where no motion should occur.

==Outputs==
Joystick Mixer Nodes have two output ports: '''left drive''' and '''right drive''' that reprsent the velocity of a left or right drive motor in a [[wikipedia:Differential_wheeled_robot|differential drive]] robot, from 0 to 1 where 0 is ''fully reverse'' and 1 is ''fully forward'' - just as should be used for [[IO Config Editor#IO Units|H-Bridge IO Unit]] input ports.
