About the WeDo
--------------

The `Lego WeDo`_ is a tethered-over-USB sensing and robotics toolkit produced by Lego for the educational market.

It's gotten lots of press, including a favorable review on the One Laptop Per Child blog, on `deployments and training in Peru`_.

It's supported by Scratch(on Windows and OSX) and by Lego's proprietary software(on Windows.)

It prominently features the LB1836_ motor driver and the LM358_ op-amp, as well as an epoxy blob with USB support.

The digital communication protocol used by the Power Functions system is documented on `Philo's Awesome Page`_.

Requirements
------------

- Python 2.7+
- pyusb (setup.py should take care of installing the dependency)

Installation
------------

From pypi:

    pip install wedo

From the source tree:

    ./setup.py install


How to Use it
-------------

    >>> from wedo import WeDo
    >>> wd = WeDo()
    # Activating the first motor full forward:
    >>> wd.motor_a = 100
    # Activating the second motor half speed/force backward:
    >>> wd.motor_b = -50
    # Current value of the tilt sensor:
    >>> wd.tilt
    # Current distance value in meters of the distance sensor:
    >>> wd.distance
