joystick2tank

Intro

Takes X & Y co-ordinates from a joystick and converts them into Left and Right values for a tank-drive system.

Usage

npm install joystick2tank

var j2t = require('joystick2tank');
var values = j2t(-30, 100); // { left: 70, right: 100 }

See example.js to see how to handle scaling values from joysticks that don't operate from -100 to 100.
