About

Turtle Storm is a turtleblocksjs plugin for the lego mindstorms NXT. It supports the motors, color sensor, touch sensor and ultrasonic sensor.

Setup

  1. Install deps

     yum install pyusb
     pip install nxt-python
    
  2. Start the NXT server

     python server.py
    
  3. Start turtle art (this plugin does not work with t.sl.o, as it is causes https mixed content warnings):

     git clone https://github.com/walterbender/turtleblocksjs
     cd turtleblocksjs
     python -m SimpleHTTPServer
    
  4. Load nxt.json plugin and have fun!
